To enable the use of new functions, the ROMs on the operation ROM board, main board, paper feed control board, and ADF main control board have been changed. This modification has been applied from the March ’92 production machines. (The old type ROMs were used only for the five machines of the February ’92 production.) To use each new function, the new type ROMs are required as shown in table 2.

NOTE: 1. The ROMs on each PCB must be replaced as a set.

2. The part number of each PCB is not changed because the old and new PCBs are interchangeable individually (interchangeability o/o). (Their suffixes, which are described on each PCB, are changed as shown in table 1 for identification.) The new ROMs are required only when the new functions are required.

3. The part numbers of each ROM are not changed, except for the ADF main board ROM (see table 1). (Their suffixes, which are described on each ROM, are changed as shown in table 1 for identification.)

4. A sorter stapler will be produced for this model. To control this unit, the ROMs for the operation ROM board and main board will be changed again. Because those ROMs will completely cover all functions of the sorter version machine, the ROMs for the sorter version machine will no longer be supplied as service parts. We will inform you of details next month. (The ROMs for the sorter stapler version machine are not available yet.)

Description Necessary

Modification

The [81/2" x 13"] key is displayed by selecting user tool no. 3 (copy/original size selection) to use 81/2" x 13" (F4 size) paper and originals.

* Paint this surface white.

Item No. 1, 2, 3, and 4 in Table 1 (All items)

Note

1. A4 originals and paper cannot be used when the [81/2" x 13"] key is pressed, and 81/2" x 13" originals and paper cannot be used when the [A4] key is pressed.

2. When the [81/2" x 13"] key is pressed, the [Tray 4] key in user tool no. 7 (disable unit) is automatically pressed and the LCT cannot be used. (This is because 81/2" x 13" paper cannot be set in the LCT.) When the [A4] key is selected again, the [Tray 4] key must be manually turned off to use the LCT.

Fuser Oil End Detection

The message display indicates "Add silicone oil" when no fuser oil is detected.

Modified Item No. 1 and 2 in table 1

3. The machine detects an 81/2" x 13" original when the original length sensor is activated by the gear on the front of the original stopper (A0287907). To ensure this, the side of the gear, which is detected by the sensor, must be painted white (see illustration in the left). This has been applied from the March ’92 production. Therefore, this procedure is required for the 5 machines of the February ’92 production or when the gear is replaced with a service part.

The silicone oil sensor (P/N-52055258) and sensor bushing (P/N-5446 4278) are required. (They have been installed from the March ’92 production machines.)

Limit

Duplex Side Fence Width Adjustment

Description Necessary

Modification

The number of the exit tray copy limit can be selected from 300, 350, 400, or "no limit" using service tool 2-15 (initial setting: 300).

The initial setting for the duplex side fence width (service tool 5-02) is changed from 0 mm to -0.6 mm. This allows adjustment of the fence width not only in the narrower direction, but also in the wider direction in the field. (It can be made 0.6 mm wider from the production setting.) The adjustable range is still the same (0 to

-1.8 mm in 0.6 mm steps).

Modified Item No. 1 and 2 in Table 1

Modified Item No. 3 in Table1

Note

Even when "no limit" is selected, "Remove copies from the copy tray" is also displayed without stopping the copy run.

NOTE: 1. If only the operation ROM board is replaced with the new type:

* The [A4] and [81/2" x 13"] keys will be displayed in user tool no. 3, but they

cannot be pressed.

* The [300], [350], [400], and [No] keys for the exit tray copy limit are displayed in

service tool 2-15, but only the [300] key can be pressed.

2. If only the ADF main control board is replaced with the new type, the machine will stop the operation when an 81/2" x 13" original is used. To recover that condition, the main switch must be turned off then on.

3. If only the ADF main control board is the old type, 81/2" x 13" originals cannot be detected.

4. If only the paper feed control board is the old type, the duplex side fence width for 81/2" x 13" paper cannot be adjusted by service tool 5-02.

Action Required Troubleshooting Retrofit Information

To enable the use of the A372 sorter stapler, the ROMs on the operation ROM board and main board have been changed as shown in table 1. This modification has been applied from the July ’92 production machines. The differences between the sorter version software (old ROMs) and sorter stapler version software (new ROMs) are listed in table 2.

NOTE: 1. The ROMs (10 pieces for the operation ROM board and 6 pieces for the main

board) must be replaced as a set.

2. The new ROMs completely cover all functions of the sorter version machine. Therefore, the ROMs for the sorter version machine will no longer be supplied as service parts. (NRG ITS had already received 2 sets of the master ROMs.)

3. The old and new operation ROM board and main board are interchangeable with one another (interchangeability o/o) for the A458 sorter version machines. (The old PCBs can still be used for the A458 sorter version machines.)

1. UNIQUE FUNCTIONS OF THE FINISHER VERSION MODEL

The major differences between the sorter version and finisher version of the F5 are as follows:

1. Permits the installation of the optional finisher (with the original recirculating motion of the RDH).

2. Permits the installation of the optional key counter bracket and printer connector unit.

3. New or modified user and service tools.

4. Advanced cover and chaptering modes.

5. Enables the use of the normal accounting mode and of the security accounting mode.

6. Satisfies the German electromagnetic field interference standard (VDE 243).

2. FUNCTIONAL DETAILS

2.1 COPY MODES

There are two copy modes: sort and stack. In the stack mode copies of the same page are grouped together. When this mode is selected with user tool number 10, the originals set in the stack original feed table of the RDH are copied just like with the sorter or sorter/stapler version machine. The originals are fed and returned to the table just once (ADF mode).

On the other hand, in the sort mode the copies are assembled as sets in sequential order. This mode is always selected when originals are set in the stack feed table of the RDH, except when the stack mode is selected. In this mode, the RDH performs the original recirculating motion (RDH mode).

The following explains the differences in original and copy paper motions when simplex or duplex copies are made from the simplex or duplex originals in the sort mode:

Technical Bulletin No. RTB-005

SUBJECT: Finisher Version Information DATE: July 15, ’93

PAGE: 4 of 23

1. Simplex original to simplex copy mode

One original feeding cycle makes one set of copies. To make more sets of copies, originals recirculate in the RDH accordingly. (Copies are always collated into sets.)

When copy delivery to the finisher is selected, the copies are inverted in the finisher in order to stack the copies with the image side down on the shift tray. The copies are stacked in page order.

When one original is set in the stack original feed table, the original is recirculated once, as usual. Then, the machine detects that only one original has been set. The original is again fed from the table, then the machine enters the original non-recirculating mode (ADF mode) to complete copying. The original stays on the exposure glass until the copy run finishes.

2. Simplex originals to duplex copy mode

In case of the other RDH and finisher systems, usually two cycles of the simplex original feeding makes one set of duplex copies. The first cycle of the original feeding is to make copies of the odd pages of originals. The copies are stacked in the duplex tray. Then, for the second original feeding, the even pages of originals are copied onto the reverse sides of the copies from the duplex tray. This motion is repeated until all the desired sets of copies are completed.

For this copier, the alternate paper feeding system is used to speed up the simplex to duplex copy job. The first original feeding is just like the other RDH and finisher systems. The odd pages of originals are copied and the copies are stacked in the duplex tray. However, the second original feeding and the following steps are different.

Unlike the other RDH and finisher systems, from the second original feeding, both the odd and even pages of originals are copied in one original feeding cycle. (This means that originals are copied in sequential order.) The alternate paper feeding system allows this.

When the odd page of originals is copied, paper is fed from the normal paper tray. The copy is stacked in the duplex tray. When the next original (the even page of originals) is copied, the copy, which was made and stacked in the duplex tray during the previous cycle of the original feeding, is fed from the duplex tray. The original image is copied onto the reverse side of the copy then the copy is delivered. The copier repeats feeding the paper from the normal paper tray and from the duplex tray alternately. This is called the alternate paper feeding. For more details, refer to the "Alternate Paper Feeding Timing Chart".

The copier repeats the above motion until the desired sets of copies are completed. (During the final original feeding cycle, only the even pages of originals are copied and all the copies in the duplex tray are fed out.) As a result, the copier can complete the copy job in the same number of original feeding cycles as the desired number of copies, plus one. On the other hand, in the other RDH and finisher systems, the original feeding cycle is repeated twice the desired number of copy sets.

Technical Bulletin No. RTB-005

SUBJECT: Finisher Version Information DATE: July 15, ’93

PAGE: 5 of 23

The duplex copies are automatically delivered to the finisher shift tray, not to the copier copy tray. The copies are stacked in page order on the tray without the inversion of copies unlike the simplex original to simplex copy mode.

NOTE: When the simplex originals to duplex copy mode is selected, if a margin of 15 mm

or more is entered in the margin adjustment mode, the copying speed is set at 61 cpm, whatever size of original or copy paper is used. Copies are made using the OPC segment for A3 size copy. (The images of 3 originals are produced for one rotation of the OPC belt.) If the difference in the selected margin between the front and reverse side of the copy image is 15 mm or greater, e.g. 5 mm margin at the left on the front side and 10 mm margin at the right on the reverse side, the copying speed is also set at 61 cpm.

This is because the originals copied on the front and reverse side are alternately copied due to the alternate paper feeding system. As the margin can be adjusted by changing the original flash (exposing) timing, the original stop on the exposure glass must correspond to the adjusted flash timing. (If a margin is created at the left, the flash timing is advanced. If a margin is created at the right, it is delayed.) When the margin is created on the front and rear of copies separately, two different flash timings alternate with each other. If the difference in the flash timing between two originals becomes greater, i.e. 15 mm or more in the margin, the original transportation cannot correspond to the alternate two different flash timings due to the limit of the original transportation speed.

For example, if a margin is created at the left on the front side of copies, after an original for which no margin is created, the original which has the margin must be transported to the exposure glass faster than usual in order to catch up with the advanced flash timing. If the margin is 15 mm or greater, the original cannot catch up with the advanced flash timing.

This copier has one more copying speed: 81 cpm. However, this is not used in case of a slow down in the margin adjustment mode. To enable 81 cpm, the copy mode for B4 size paper (B4 size copy mode), where the images of 4 originals are produced for one rotation of the OPC belt, must be used. In the A4 size copy mode three originals are fed into the RDH from the stack original feed tray before the first original is flashed. For the B4 size copy mode, it is two originals. Due to this, the original transport speed in the B4 size copy mode is almost the same as that in the A4 size copy mode, even though the copying speed of the B4 size copy mode is 81 cpm. Therefore, even if A4 size copies are made using the B4 size copy mode, there is not enough margin in the original transportation speed.

3. Duplex original to duplex copies mode

The front side of originals is copied during one cycle of original feeding. The copies are stacked in the duplex tray. At the same time the originals are inverted and returned onto the original table. Due to this, the reverse side of the originals is copied during the next cycle of the original feeding. The images are copied on the reverse side of the copies from the duplex tray and the duplex copies are automatically delivered to the finisher shift tray, not to the copier copy tray. The copies are stacked in page order on the tray without the inversion of copies as in the simplex originals to duplex copy mode.

To make more sets of copies, the above motion is repeated. (Copies are always collated into sets.) This means that the original feeding cycle is repeated twice the desired number of copy sets.

4. Duplex original to simplex copies mode

One cycle of original feeding makes one set of copies. For each original feeding, the front side image is copied and the copy is stacked in the duplex tray. Then the original is inverted in the RDH and the reverse side image is copied onto the copy from the duplex tray. After the images on both sides of the original are copied, the original returns to the original table. To make more sets of copies, originals recirculate in the RDH accordingly. (Copies are always collated into sets.)

When copy delivery to the finisher is selected, the copies are inverted in the finisher in order to stack the copies with the image side down on the shift tray. The copies are stacked in page order.

2.2 ALTERNATE PAPER FEEDING TIMING CHART

Technical Bulletin No. RTB-005

SUBJECT: Finisher Version Information DATE: July 15, ’93

PAGE: 8 of 23

*1 to *8 on the charts in the previous page show the key points for understanding the alternate paper feeding. Refer to the explanation below for each key point. The timing charts are based in the following copy mode conditions:

Upper One: Two sets of copies are made from 10 originals in the simplex original to duplex copy mode.

Lower One: A large number of copy sets are made from 20 originals in the simplex original to duplex copy mode. The timing chart shows only part of the copy run.

*1: "Original Feeding Timing" shows when each original feed starts from the stack

original feed table. The numbers 1 to 10 identify the originals. The chart means that the 10 originals are recirculated three times.

*2: "Paper Feed Timing" shows the timing when each paper is fed from the LCT. The

numbers correspond to the number of the original which will be copied on the front side of the paper.

The chart shows only odd number because the even numbered originals are copied on the reverse side of the paper.

The paper feed start timing is different when paper is fed from the LCT, 1st tray, 2nd tray, and 3rd tray. This is because paper transportation takes more time depending on where the paper feed starts and where images are transferred to the paper. The time for the LCT is the longest and that for the 3rd tray is the shortest. If the paper is fed from a station other than the LCT, the paper for the first original starts being fed as shown in the dotted lines. The following paper feed intervals are the same as that for the LCT.

*3: "Duplex Tray Entry Timing" shows when the paper activates the duplex entrance

junction sensor and is delivered to the duplex tray. The number on top of each entry timing corresponds to the number of the original which has been copied on the front side of the paper.

*4: "Duplex Feed Timing" shows when the paper for each original is fed from the

duplex tray. The number on top of each duplex feed timing correspond to the number of the original which will be copied on the reverse side of the paper.

As the timing chart shows, during the first original feed cycle only the odd numbered originals are copied onto the paper fed from the paper tray. During the 2nd cycle the odd numbered originals are copied as in the first cycle, and also even numbered originals are copied onto the paper fed from the duplex tray. Copying for the front and reverse sides is done alternately in this period. (This is the alternate paper feeding.) For the 3rd original feed cycle (i.e. the last original feed cycle) only the even numbered originals are copied onto the paper from the duplex tray, completing the copy run (two sets of five duplex copies are completed).

Technical Bulletin No. RTB-005

SUBJECT: Finisher Version Information DATE: July 15, ’93

PAGE: 9 of 23

*5: When the LCT is used the original to be copied starts being fed from the stack

original feed table and the paper for it starts being fed from the LCT right away. During the first original feeding cycle, the 2nd original (and also the following even

numbered originals) is just fed and returned without being copied. During the 2nd cycle, all originals are copied. Finally during the last original feed cycle, only the even numbered originals are copied.

*6: The copy of the first original enters the duplex tray just after the 10th (last) original

starts being fed and before the first original starts being fed for the 2nd feed cycle. This duplex tray entry timing for the first copy does not depend on the paper being fed from the LCT, first tray, 2nd tray, or 3rd tray. This is because the time for the paper to enter the duplex tray after images are transferred to the paper is constant no matter where paper is fed from.

Just after the 3rd paper has entered the duplex tray, the paper which first entered in the duplex tray starts being fed from the duplex tray in order to match with the copying for the 2nd original during the 2nd feeding cycle.

*7:‘ The 2nd copy of the first original enters the duplex tray just before the first original

starts being fed for the last original feed cycle. When this happens, the last copy in the duplex tray just starts being fed. This means that

a) when the first copy made during the next original feed cycle enters the duplex tray and b) if the number of originals is 10 or less (as in this case) then c) the duplex tray is empty even in the alternate paper feeding motion.

*8: The lower timing chart shows simplex original to duplex copying using 20 originals.

There are copies remaining in the duplex tray (approximately 6 copies in this case) when the first copy made during the next original feed cycle enters the duplex tray.

This chart also shows that the copy of the first original enters the duplex tray just after the 10th original starts being fed, as in the upper timing chart.

2.3 ACCOUNTING MODES

There are two types of accounting mode: security accounting mode and (normal) accounting mode. In the normal accounting mode, all of the operators can use the user access code mode in user tool number 9. In the security accounting mode, only key operators whose user access codes are registered by their service representative can use all the user access code mode. (For the user access code mode, refer to the operating instructions.)

1. How to enter the copy mode in the accounting mode

Enter one of user access codes by pressing the Number keys.

2. How to leave the copy mode in the accounting mode

Press the Clear/Stop key while pressing the Clear Modes key.

3. How to set the accounting modes

1. Normal Accounting Mode Press the "Access Code" key in service tool 2-08. Then enter appropriate user access codes with user tool number 9.

2. Security Accounting Mode (1) Be sure that the "Free Use" key is selected with service tool 2-08. Then enter an appropriate user access code with user tool number 9. The user access codes entered in this condition will be the codes for the key operator.

(2) Press the "Access Code/Super User Mode" key with service tool 2-08. Then return to the normal screen.

(3) Enter appropriate user access codes with user tool number 9. This will be the codes for normal operator.

4. How to enter the copy mode in the accounting mode for servicing

The accounting mode is canceled when DIP switch 101- 2 on the main control board is ON. Note that DIP switch 101-2 is commonly used to enable accessing the service tool password "999900." DIP switch 101, 102, and 103 on the main control board must be kept at the initial setting, except 101-1 and 101-2 which have the same functions as the sorter and sorter stapler versions.

CAUTION: When the main control board is replaced with a new one, all data in user tool number 9 must be cleared in order to reset RAM on the main control board and start up the use of the user access code mode. (This is the same as the data in service tools 3-01 to 3-07. All data must be cleared when the main control board is replaced.)

2.4 COVER SHEET AND CHAPTERING MODES

The following are different from the cover sheet and chaptering modes of the sorter stapler version model. They are features unique to the finisher version model.

1. With user tool number 8 " Select Special Tray," the 1st paper tray can be designated as only for the cover sheet, and one of the 1st, 2nd and 3rd paper tray can be designated as only for the slip sheet for the chaptering mode. Two paper trays can be designated separately for the cover and slip sheets at the same time.

When no paper tray is designated, the paper in the 1st paper tray is automatically used for the cover and slip sheets, just like in the sorter stapler version model.

2. In the chaptering mode with the simplex originals to duplex copies mode, the original designated as the first page of each chapter is automatically copied onto the front side of the copy. For example, when the 4th original is designated, the reverse side of the 2nd copy will be blank and the 4th original is copied onto the front side of the 3rd copy.

In this mode, users can select to have the designated original copied onto special paper (slip sheet) or normal paper.

3. When the back cover is selected in the cover mode, it can be selected with user tool number 10 "User Utility/Reverse Back Cover Sheet." In this case, the setting decides if the image of the back cover faces inside of the copy set (normal) or outside.

4. In the chaptering mode, up to 15 originals can be designated by pressing the "Next" key, although for the sorter stapler version model, up to 10 can be.

5. Even in the duplex copy mode, the copy for the original which is designated as the cover and slip sheets does not enter the duplex tray. This is to enable the use of copy paper up to 163 g/m2 of paper weight. It is usually up to 120 g/m2 for duplex copies. Therefore, the cover and slip sheets have images only on one side. Refer to the following explanation for understanding how this is done. (In the chaptering mode with the simplex originals to duplex copies mode, if the copy for the designated original to normal paper is selected, the copy will enter the duplex tray and have images on both sides as usual.)

1. How the copies are collated into sets in the duplex copy mode with the cover or chaptering mode

In the simplex originals to duplex copy mode, the original next to the designated one is copied on the front of the copy next to the cover or slip sheet, resulting in having the reverse side of the cover and slip sheets blank. In the duplex original to duplex copy mode, the reverse side of the designated original is not copied, resulting in having the reverse side of the cover and slip sheets blank. (Therefore, the reverse side of the designated original should be blank.)

Technical Bulletin No. RTB-005

SUBJECT: Finisher Version Information DATE: July 15, ’93

PAGE: 12 of 23

In the simplex or duplex original to duplex copy mode, the duplex copies are automatically delivered to the finisher shift tray, not to the copier copy tray. The copies are stacked in page order on the shift tray without being inverted. However, as the copy image on the cover and slip sheets is made while the reverse side copies are made, in order not to enter the cover and slip sheets into the duplex tray, only the cover and slip sheets are inverted in the finisher to stack all copies in page order.

2. How the designated original is copied in the duplex original to duplex copy mode

In the duplex original to duplex copy mode, although the original designated with the cover or chaptering mode is always copied on the front side of the cover or slip sheet, it is copied during the second original feeding cycle, not during the first one. This is because the cover or slip sheet must enter the duplex tray if the designated original is copied during the first original feeding cycle. To allow this, the original recirculating motion in this mode is different from that in the duplex original to duplex copy mode without the cover or chaptering mode, as follows:

1. During the 1st Original Feeding Cycle: The front side of the originals set in the RDH is copied as usual. However, the designated original is not copied during this cycle. Before the designated original feeds out to the stack feed table, it is not inverted. As a result, the front side (image side) of the designated original only faces the direction of the reverse side of the other originals and stacked in the stack feed table.

2. During the 2nd and the Following Original Feeding Cycle: During the 2nd cycle, the reverse side of the originals is copied. The designated original is copied during this cycle. The completed duplex copies are delivered to the shift tray. As the copy image on the cover or slip sheet is made while the reverse side of the other originals is copied, only the cover or slip sheet is inverted in the finisher to stack all copies in page order.

For the following cycles, both sides of the originals, including the designated original, are copied as usual in the duplex original to duplex copy mode until all the desired copy sets complete. Even during this period, only the cover or slip sheet is inverted in the finisher to stack all copies in page order.

3. During the Last Original Feeding Cycle: After completing the copy run, one more original feeding is done. This is to return the designated original, which had been made side down during the first original feeding cycle, into the original setting. (The designated original is inverted before it feeds out to the stack feed tray, and the other originals are not.)

As a result, the original feeding is twice the desired number of copy sets plus, one.

2.5 DIFFERENCES IN MECHANISM BETWEEN THE ADF AND RDH

[ADF Type]

1. Recycle Arm Solenoid

The ADF feeds originals just once for each copy job. On the other hand, the RDH recirculates originals according to the desired copy set number. Due to this, in the RDH, the recycle arm is repeatedly placed on the original stack and repeatedly returned for each copy set. If the existing type of the solenoid is used, it will malfunction due to heat generated by the repeated on and off operation.

To cope with this, a new solenoid has been used to operate the recycle arm. It is a two-way solenoid, which is the same as the one used for the finisher junction gate, and once the position of the solenoid plunger is changed according to the signal from the CPU, this solenoid keeps its position until a different signal is generated. This works using a permanent magnet installed in the solenoid.

2. Original Transport Drive Motor

[RDH Type]

There are three dc motors (#AX060027) to drive the original transport rollers. In the RDH, the motors have been changed to more durable ones. There is a groove for an E-ring in the shaft of the existing motor, but the motor for the RDH (#59365501) does not have such a groove.

3. Instruction Decal

There is a decal (#AA000114), which instructs how originals are set, in the stack original feed table. There is no problem with the ADF system, but it has been found that electrostatic charges are generated in the decal due to the recirculating motion of originals. As a result, the bottom original stacked in the original table tends to stick to the decal and misfeed.

To cope with this situation, the decal has been moved to the right end of the original table cover.

A wait or busy signal from the finisher stays generated for more than 25 seconds. After the copier CPU sends a status request signal to the finisher, there is no response signal from the finisher for more than 10 seconds. A status that the finisher cannot make copies in both shift tray and staple modes due to a defective motor is detected. A status that the finisher cannot make copies in shift tray mode due to a defective shift motor is detected. A status that the finisher cannot make copies in staple mode due to a defective motor is detected.

Action Required Troubleshooting Retrofit Information

Even when the oil path is cleaned at every PM visit as described in the service manual, fuser oil might overflow from the oil receiver (in the main body side).

If inside of the oil tube going to the oil tank (P/N-A0284904) becomes very dirty, the tube might clog and oil might overflow from the oil receiver.

If the oil does not pass through smoothly, replace the tube with a new one. At the same time, clean or replace the oil tank with a new one to prevent dirty oil from generating circulating.

If paper generating a lot of paper dust is used, it is recommended to replace the tube and oil tank every 1,000,000 copies.

CLASSIFICATION:

Action Required Troubleshooting Retrofit Information

Theory

A constant current cleaning power pack is used. –20µA for the cleaning roller bias and –10µA for the scavenging roller bias are applied. The larger negative bias for the scavenging roller attracts the positively charged toner from the cleaning roller to the scavenging roller.

To make the cleaning roller bias constant, a varistor is used. The bias is approximately –83 volts, and excessive current is discharged through the varistor.

FROM: 2nd Technical Support Section

MODEL: F5 (Gestetner 25101/ nashuatec 53101)

Varistor

As the cleaning carrier wears out, the electrical resistance of the carrier increases. Because a constant current power pack is used, the scavenging roller bias increases. If the carrier is new, the scavenging roller bias is approximately –340 volts. (If the varistor is removed, the cleaning roller bias is approximately –170 volts.)

For the cleaning roller bias, if the varistor is not used and the cleaning carrier wears out, too much bias voltage will be applied to the toner collected by the cleaning roller. Because a high negative voltage is applied to the positively charged toner, the collected toner on the cleaning roller might be re-attracted to the OPC surface which is given a positive charge by the PCC. This will appear on copies, especially on the leading edge, as a faint dirty background. The varistor prevents this.

NOTE

If the copy volume is extremely low and if often only a few copies are made from an original, the period of the main motor rotation for each copy becomes longer. This motor also drives the cleaning unit and the cleaning carrier wears out faster than usual. In such a case, no cleaning bias voltage is applied around the end of the cleaning carrier life time (400,000 copies) because all current is discharged through the varistor due to too high resistance of the carrier. As a result, a dirty background appears on copies.

If this occurs, replace the cleaning carrier with new one earlier than usual. Otherwise, remove the varistor from the cleaning unit. For such a low copy volume customer, the toner re-attraction to the OPC does not occur even without the varistor.

Cleaning power pack

PAGE: 2 of 3

Checking the cleaning and scavenging bias

Pull out the cleaning unit. Remove the varistor.

NOTE

Although the cleaning power pack is a constant current type, the varistor makes the bias voltage to the cleaning roller constant. Removing the varistor allows for adjusting the amperage.

Varistor

Remove the rear left cover and set an ammeter to the cleaning power pack as shown.

NOTE

To measure the cleaning roller side, disconnect the wire from the "CL" terminal

CL S

(indicated on the power pack). Then, set an ammeter between the wire connector and

terminal. To measure the scavenging roller side, use the "S" terminal.

WARNING

Ammeter

When the main switch is ON, never touch anything inside the rear left cover to avoid possible injuries.

Turn on the main switch. After the copier enters the stand-by condition, access the service tools.

Select [5-04] "I/O Test". Press the "Motor" key, then press the "Main" and "OPC" keys. Press the "Lamp/Sol" key, then press the "QL" key.

NOTE

This procedure is necessary to avoid OPC deterioration.

Press the "P. Pack 2" key, then press the "Cleaning Bias" key to measure the amperage. It must be –20 ± 0.5 µA.

Set an ammeter to the "S" terminal side, then press the "Scav. Bias" key. The amperage must be –10 ± 0.5 µA.

If the values do not meet the standards, adjust the amperage by turning the VR above each terminal.

When inch size originals are used, make a slot as shown to stop the original stopper at the 81/2 inch position.

CAUTION

When the slot is made, operating cautions must be instructed to operators, so that operators can adjust the original stopper position correctly according to the original size set in the ADF. The A4 position and 81/2 inch position are very close. If the original stopper position is not proper, original misfeeds will occur.

Action Required Troubleshooting Retrofit Information

The following contains remarks for common situations. Be sure to follow all warnings, cautions, and notes described in the service manual, including those not described in the following.

1. Machine Installation

1. Select the environment conditions as described in "1.2.2. Environment."

2. To avoid unnecessary service calls, explain the items described in "1.6 User Guidance

Items" to the customer before installing the machine.

3. Use the following cautions for the copier installation:

• When the optional finisher is not used, the sub-tray must be ordered and used.

MODEL: F5 (Gestetner 25101/ nashuatec 53101)

• Distribute the cleaning carrier evenly by turning the knob. The cleaning unit has no agitation mechanism as the development unit does.

• Be sure to return the developer from the development roller to the inside of the unit before pulling out the OPC unit. Do this by turning the development knob.

• Never remove the oil supply unit from the fusing unit to prevent oil marks on copies. It can be removed only when the oil blade, metering blade, and oil supply felt are replaced with new ones.

• The machine is set up for a 400 volts 3-phase power supply (European version) or 240 volts single phase power supply (U.S.A. version) at the production line. To install the machine in areas where the power supply is 380 or 415 volts (220 or 230 volts single phase), be sure to follow steps 28 to 32 described in "1.3 Main Body Installation."

• Using a level gauge, level the machine flat on the floor. This is mainly to prevent affecting the tracking operation of the OPC belt.

• When inch size originals are used, make a slot to stop the original stopper at the 81/2 inch position. When the slot is made, operating cautions must be instructed to operators, so that operators can adjust the original stopper position correctly according to the original size set in the ADF. If the original stopper position is not proper because the A4 position and 81/2 inch position are very close, original misfeeds will occur.

SUBJECT: Service Remarks DATE: Feb. 15, ’94

PAGE: 2 of 9

• Before making copies, carry out forming for the developer, OPC belt, and cleaning carrier (in this order) using service tool [3-04].

• Before checking copy image quality, check the toner density control data in the service tool [4-02] screen. Perform setting C if the data is not correct. Also, check the AID reference voltage in the [4-03] screen using the PC-1 chart. Perform setting A if the value is not correct. (If the AID reference voltage is within the standard, you do not have to perform setting A.)

• The side-to-side registration must be checked for all paper trays.

• The erase margin and duplex side fence width must be checked for all paper sizes.

• If the erase margin is not sufficient, thin black lines may sometimes appear on copies

(especially on the side edges of copies in the ADF mode). This is because the side-to-side registration varies slightly on each copy if an operator does not set the original side guides securely. You have to make more than 10 copies and check that all of them are within specifications after the adjustment.

• Check the side-to-side registration of the back side of the copy in the duplex mode before installing the peripherals. If the value is outside specifications, you have to remove the copier right cover.

• Explain all user tool items and some of the service tools to the customer. Then, listen to the customer’s requests and set the copier accordingly. Keep the set items using the format described in "1.7 Setting User and Service Tools." (If the main control board is replaced, you can set all items again using the format.)

4. Use the foolowing cautions for the peripheral installations:

• When you install the horizontal transport unit (LCT accessory) in the copier, while holding down the small white roller of the upper left guide plate, tighten the lock lever assembly. Be sure that the lock lever bracket pushes down the upper left guide plate when it is locked.

• Align the position of the LCT and finisher with the copier. This is to prevent paper misfeeds where the units connect. For details, refer to their installation procedure explanations.

• The optical fiber cable connectors must be set to the sockets properly as they have the setting direction.

• The printer interface board, printer harness, 2 connector joint studs, and 4 nylon studs, which are the copier’s accessories, are required for the printer connector unit installation.

2. Paper Feed Section

• Do not touch the feed, reverse, and pick-up roller surfaces with bare hands.

• Install the feed roller in the correct direction as it has a one-way clutch built-in.

• Because the torque limit pressure is properly adjusted, do not loosen the torque limiter

stopper screws.

• Because the side-to-side registration adjustment mechanism is also provided on the original side (ADF and SADF), make adjustments for each tray on the basis of the platen cover mode.

• When you adjust the leading edge or side-to-side registration, be sure to set the paper side guides of the paper tray securely.

3. Optics Section

• Every 200K and at every visit, clean the exposure glass using glass cleaner or alcohol. Then wipe with silicon oil. Wiping the exposure glass with silicon oil helps transport originals more smoothly and prevent original misfeeds caused by static electricity. Wipe the mylar strips on the original transport path for the same reason.

• If the cooling air flow to the xenon lamp and flash power supply unit becomes low, the flash voltage step will exceed 28 earlier than normal. Be sure to clean the air filters every PM.

• Working near the lamp is dangerous. Never work near the lamp without turning off the main switch and waiting at least 1 minute for discharge.

• To avoid wiring problems of high voltage parts, never disassemble the connector going to the xenon lamp.

• Take care and check the position of the harness going to the xenon lamp.

• To avoid xenon lamp damage, firmly fit the xenon lamp connectors to the sockets. Push

each connector end with your fingers, then tighten two screws.

• Be sure to wire the three flash power source lines correctly, the white wire (from the trigger transformer), red line and black line from the top. If wired incorrectly, the lamp may burn up.

• When reinstalling the xenon lamp in the unit, position the lamp exactly. If the position is not correct, the life time of the lamp might be reduced. Insufficient light intensity will increase the lamp voltage repidly due to process control.

• Normally adjusting the uneven illuminance is prohibited. It seems difficult to return the illuminace to the original setting if you change the position of the front and rear reflectors.

4. Safety Notices for Flash Power Supply

High voltages of 1,070 to 2,000 V are applied to the xenon lamp (flash lamp) to produce light immediately. Therefore, working near the xenon lamp is dangerous after removing the exposure glass. Never work near the lamp without turning off the main switch and waiting at least 1 minute for discharge.

Conditions for discharge of the flash power

For safety purpose, the power charged to light the xenon lamp is discharged under the following conditions:

(1) When a "Service Call" or "Error Reset" condition is detected and the machine is stopped during copying or operating with the free run mode in the service tools.

(2) When an original or copy paper jam occurs and the machine is stopped during copying or operating with the free run mode in the service tools.

(3) When any doors are opened and the machine is stopped during copying or operating with the free run mode in the service tools.

NOTE

When the above three conditions happen, the machine is stopped after an extra flash. The flash power is discharged immediately.

(4) When the main switch is turned off.

(5) When the "Dis" (the flash discharge) key in service tool [5-04] "I/O test mode" is pressed.

NOTE

When the above two conditions happen, the flash power is discharged by the discharge circuit built-in the flash power supply unit. In this case, it takes approximately 1 minute to complete discharging.

CAUTION Even in the copy stand-by condition, if the flash power is manually charged using

the "Charge" key in service tool [5-04] "I/O test mode" or the charge key (blue push switch ) installed in the flash power supply unit, be sure to discharge it by turning off the main switch or using the I/O test mode before accessing the xenon lamp.

5. OPC Unit

• Set the OPC belt so the home mark is on the far side.

• Put far side of the OPC in the OPC sensor and set it in the center.

• Never touch the OPC surface, and position the OPC belt carefully to prevent bending it.

• Do not expose the OPC belt to daylight for more than a few minutes. When not

installed, keep the OPC belt in its case and store it in a cool, dark place. If copying is done while the exterior covers are off and in slight daylight, even after it is set in the copier, the copy image becomes extremely light.

• Never use alcohol or other chemicals to clean the OPC.

• Because the slide guides have sharp edges, keep them in the main body while servicing.

6. Potential Sensor

• Blow air to remove toner and dust from the electrode of the potential sensor. To prevent clogging or jamming, do not use a rag.

7. Charge, Pre-cleaning, and Transfer/Separation Corona Units

• Clean the unit casings with water first to remove NOx. Then clean them with alcohol if any toner still remains on the casings.

• The corona wires can be cleaned only with a dry soft cloth. Using water or alcohol might damage the coating of the wire surface.

Technical Bulletin No. RTB-014

SUBJECT: Service Remarks DATE: Feb. 15, ’94

PAGE: 6 of 9

8. Cleaning Unit

• When you pull out the cleaning unit and turn the cleaning knob, toner will fall from the toner exit pipe of the unit. When you do this, place a sheet under the toner exit pipe to prevent the OPC unit from becoming dirty by toner.

• Never put in cleaning carrier on the left side (scavenging roller side).

• The air filters have a setting direction. Be sure that the side with a red line on the edge

is facing the inside of the unit.

• Because the slide guides have sharp edges, keep them in the main body while servicing.

• Lay paper in place where the cleaning unit is put. Be sure there is no metal debris

present that can cause damage. Metal screws, paper clips, etc. attracted by the cleaning roller can scratch the roller and blade.

• Because the cleaning unit has no horizontal agitating roller, do not tilt the unit when the cleaning carrier is in the unit.

• When the cleaning carrier is in the cleaning unit, do not turn the unit up side down.

9. Development Unit

• When you use a vacuum cleaner to clean the development unit, heavy electrostatic will occur. To avoid damage of electrical parts, be sure to do the following:

(1) Pull out the toner density control board.

(2) Disconnect the harness from the ID sensor board and ground the board using the development unit grounding harness (copier accessory).

• Collect the developer by turning the development knob before pulling out the unit. It might scatter, or damage the OPC.

• The air filter has a setting direction. Be sure that the side with a red line on the edge is facing the inside of the unit.

• Clean the developer around the air filter case as the place is very close to the OPC surface. If t his is n ot done, the OPC may b e damage d.

• Do not lubricate the sleeve gears and the other gears in the development unit to avoid toner adhering to the gears. Lubricate the two projections of the unit drive joint roller with a small amount of G-40M when the unit does not slide in the main body smoothly.

• No developer should be allowed to fall on the toner density control board. Otherwise the board migh t be damage d.

• Because the slide guides have sharp edges, keep them in the main body while servicing.

SUBJECT: Service Remarks DATE: Feb. 15, ’94

PAGE: 7 of 9

10. Fusing Unit

• After the oil supply unit is removed and reinstalled, oil marks might appear on copies. This is due to the toner built up on the edges of the blades. If this occurs, replace the fusing blade, metering blade, and oil supply pad with new ones as a set.

• To avoid spilling the silicon oil, do not tilt the unit.

• Fit the oil supply pad and soak it with silicon oil so its surface is coated sufficiently. If

coating is not sufficient, the fusing roller will be damaged.

• Clean the oil pan using a dry cloth every 200K copies. At the same time, check the oil hoses, drains in the oil pan, oil exit from the unit, and oil receiver of the main body side to make sure that the oil passes through smoothly.

• If inside of the oil tube going to the oil tank becomes very dirty, the tube might clog and oil might overflow from the oil receiver. If the oil does not pass through smoothly, replace the tube with a new one. At the same time, clean or replace the oil tank with a new one to prevent dirty oil from circulating. If paper generating a lot of paper dust is used, replace the tube and oil tank every 1,000K copies.

• To prevent damage of parts, grasp the front grip and rear upper edge of the unit frame when you lift the unit.

• Be careful as there is a projection for the oil returning guide at the bottom of the unit. Set the oil returning guide aside from the work table.

• Do not touch the heater glass surface and handle it carefully to prevent damage.

• Do not adjust the fusing temperature when referring the value displayed on the service

tool [5-03] screen. It does not shown the actual fusing temperature. The displayed value shows what fusing temperature the CPU takes at the moment. The displayed value will return to the standard value a few minutes later.

• Because the slide guides have sharp edges, keep them in the main body while servicing.

11. Duplex/Exit Unit

• Do not move the side fences manually. The timing belt behind the fences might slip out of the pulleys.

• Avoid touching the surface of new duplex feed and reverse rollers.

• Because the torque limit pressure is properly adjusted, do not loosen the torque limiter

stopper Allen screws.

• When reinstalling the lock lever assembly of the horizontal transport unit, be sure that the assembly completely locks the upper guide plates and that the lock lever bracket pushes down the upper left paper guide plate of the unit. Otherwise, paper misfeeds might occur there.

• Before this adjustment, you should finish the adjustments of the side-to-side registrations in the front side copy for all paper trays.

12. ADF

• The ADF rear cover is made of metal. So, the cover may touch electric elements on the boards shoring them out when you remove the cover. Be sure to turn off the main switch when you remove the ADF rear cover.

• Before adjusting the side-to-side registration in the ADF/SADF modes, adjust the side-to-side registrations for all paper trays and for the front and back side copies.Before adjusting the leading edge registration in the ADF/SADF modes, adjust the leading edge registrations in the platen (not ADF and SADF) mode.

13. User and Service Tools

• The data for the user and service tools will be cleared if the main control board is replaced. Write down the set data and use it in that case. The data in user tool [1] "Total sheets copied", [9] "User access code", service tools [3-01] to [3-07] must be cleared in order to reset RAM on the main control board and start up the use of these modes.

• The "Actual Target T.D." value shown in service tool [4-02] is changed in a range of ±

0.74 volts from the "Setting Target T.D." value according to the ID sensor output. Therefore, if the "Setting Target T.D." is abnormal, a proper level of the target to control the toner density might not be obtained. Do not press the "Developer Forming "key in service tool [4-02] without carrying out setting C. (The "Developer Forming" key in service tool [3-04] does not change the "Setting Target T.D.")

• Since the utility mode functions are not standard to the machine, the customer’s approval is required when they are set.

• Do not set any modes not mentioned in the utility mode table. The machine might not work properly.

14. LCT

• Do not touch the surface of the new rollers with bear hands.

• Be sure that the feed roller has the setting direction.

• Check the side-to-side registration of the copies from the LCT when the LCT is removed

and installed. The side-to-side registration will be changed in that case.

15. Others

• Golden screws (zinc plated) in all locations show a location adjusted during assembly. Therefore, pay attention to how the screw is set originally before you start working. When the screw is loosened, adjustment is required.

• The Key-operator Only key has been added in user tool [9]. The key can be used only when the security accounting mode is selected with service tool [2-08], and is displayed after pressing the Set Code key in user tool [9]. (In the security accounting mode the Set Code key cannot be pressed when the machine is operated by inputting the normal user access codes, but can only be operated by the key-operator’s user access codes.)

By selecting the Key-operator Only key, only selected key-operators can disable the use of the normal user codes.

• When a copy run finishes using the simplex to duplex copy mode and RDH, and if the number of originals is odd and the reverse side of the last copy becomes blank, the beeper sounds and a message of "The reverse side of the last copy is blank." is displayed.

• "Chaptering" and Chapterization" keys, which are displayed when the simplex to duplex copy mode then the chaptering mode are selected, have been changed to "Special sheet" and "Normal paper."

2. Main Board ROMs

• Allows to select the 1st paper tray when in the APS mode. (The 1st paper tray is not selected with the auto tray switching mode.)

• The user code counter in user tool [9] counts 2 sheets for each A3 or 11"x17" copy side, if the A3 double copy count mode is selected with service tool utility 6-5-9. The counter also counts 2 for 1 sheet of copies when in the duplex copy mode.

For example, when 1 duplex copy is made on A3 or 11"x17" paper, the counter counts 4 for 1 copy. With the old ROMs, the counter counted 1 regardless of the paper size and copy modes. The new way of counting matches that of the mechanical (total) counter.

• Service tool utility 13-5-10 "Automatic accounting mode selection by auto reset" has been added. When this is selected and security or normal accounting mode is selected with service tool [2-08], the copier automatically leaves the copy mode and requires a user access code after the period set with service tool [2-13] (the auto reset time).

• When the Exit originals to tray mode is selected with user tool [10], the Stack mode is automatically selected. The selected Stack mode returns to the Sort mode whenever the Exit originals to tray mode is canceled. With the old ROMs, the Stack mode had to be selected separately to use the Exit originals to tray mode.

Originals

1st Transport Sensor

Right Turn Roller

RDH Software Modification

In case of A4 originals, after the original is fed from the original table, the original is stopped once at the entrance of the intermediate transport section as soon as the 1st transport sensor detects it. Soon after this, the original starts being transported again at the next original’s feed timing.

It was found that the original stop position at the entrance of the intermediate section tends to be delayed. If this happens, the following problems might occur:

When the original is stopped, the previously fed original is stopped at the exit of the intermediate transport section. Usually, the leading edge of the original is just in front of the right turn roller. However, if the stop timing is delayed, the leading edge of the original will reach the right turn roller as illustrated above.

The right turn roller (also the original feed roller, and 1st and 2nd relay rollers) is rotated by the original feed motor. At the original stop timing the motor stops. However, as the pulley that drives the right turn roller has a built-in one-way clutch, the right turn roller still turns just slightly even after the motor stops.

As a result, the original which has reached the right turn roller will continue to be transported a bit. At that moment, the original rubs against the 2nd relay roller as the roller is stopping. This will make the reverse side of the original dirty (small rubber roller mark) after many original recirculations. Also, if the original is accidentally transported too far by the right turn roller after the stop timing, it will be detected as a misfed original during the following original transportation.

To prevent original misfeeds and dirty reverse sides, the ROM on the ADF control board has been modified. With the new ROM, the original stop timing by the 1st transport sensor is strictly controlled.

The copying speed is reduced in the following 3 cases. Explain the following if the customer is unfamiliar with the subject items.

1. In the case of selecting a margin of 15 mm (5/8") or more using the margin adjustment mode with the simplex originals to duplex copy mode and RDH mode, the copying speed is set at 61 cpm, whatever size of original or copy paper is used. (The images of 3 originals are produced for one rotation of the OPC belt.) If the difference in the selected margin between the front and reverse side of the copy image is 15 mm (5/8") or greater (e.g. 5 mm (2/8") margin at the left on the front side and 10 mm (3/8") margin at the right on the reverse), the copying speed is also set at 61 cpm.

REASON

FROM: 2nd Technical Support Section

MODEL: F5 (Ricoh FT9101/ nashuatec 53101/ Gestetner 25101)

The originals copied on the front and reverse side are alternately copied due to the alternate paper feeding system in the simplex originals to duplex copy mode. As the margin is adjusted by changing the original flash (exposure) timing, the original stop on the exposure glass must correspond to the adjusted flash timing. (If a margin is created at the left, the flash timing is advanced. If a margin is created at the right, it is delayed.) When the margin is created on the front and rear of copies separately, two different flash timings alternate with each other. If the difference in the flash timing between two originals becomes too great (i.e. 15 mm (5/8") or more in the margin), the original transportation cannot correspond to the alternate two different flash timings due to the limit of the original transportation speed.

For example, if a margin is created at the left on the front side of copies, after an original for which no margin is created, the original which has the margin must be transported to the exposure glass faster than usual in order to catch up with the advanced flash timing. If the margin is 15 mm (5/8") or greater, the original cannot catch up with the advanced flash timing.

This copier has one more copying speed: 81 cpm. However, this is not used in case of a slow down in the margin adjustment mode. To enable 81 cpm, the copy mode for B4 size paper (B4 size copy mode), where the images of 4 originals are produced for one rotation of the OPC belt, must be used. In the A4 size copy mode three originals are fed into the RDH from the stack original feed table before the first original is flashed. For the B4 size copy mode, it is two originals. Due to this, the original transport speed in the B4 size copy mode is almost the same as that in the A4 size copy mode, even though the copying speed of the B4 size copy mode is 81 cpm. Therefore, even if A4 size copies are made using the B4 size copy mode, there is not enough margin in the original transportation speed.

2. In the case of selecting the back cover sheet mode with the RDH mode, the copying speed speed, whatever size of original or copy paper is used. (The originals are alternately fed only for the first feed cycle.)

REASON

At normal copying speed, the copier cannot catch up with the switching to a cover sheet from the normal paper when the last original in the RDH is detected. When the last original is detected while the paper is being fed, the paper for the last original is already fed.

The reduction of the copying speed enables the copier to stop feeding the paper after the last original is detected. It switches to a cover sheet. After the first original feed cycle, the number of originals is known. For a continuous copy run, the copying is done at normal speed because the copier can stop feeding the normal paper and feed a cover sheet for the last original.

becomes half of normal copying

3. When with the simplex originals to duplex copy mode and RDH mode the paper near end condition is detected (the paper end indicator in white letters, not in red, appears in the paper tray selector key) while the paper is being fed from the first tray or LCT, the copying speed becomes 2/3 of normal copying speed, whatever size of original or copy paper is used. (One in three original feedings is skipped.)

REASON

In the simplex originals to duplex copy mode, the alternate paper feeding system is used. The copier repeats feeding paper from the normal paper tray for an odd page of originals and from the duplex tray for the even page of originals alternately.

Due to the difference of the paper transportation length, when the paper in the normal paper tray runs out during copying, the copier cannot stop feeding the paper from the duplex tray because it is already fed. If this occurs, a paper misfeed condition detected (for at the normal paper tray) and the jam indicator will be indicated prior to detecting the paper end condition. To prevent this, after feeding paper from the normal paper tray, the original feeding for the copy from the duplex tray is paused when the paper near end condition is detected while the paper is being fed from the first tray or LCT.

Technical Bulletin No. RTB-018

SUBJECT: Restriction of copying speed (F5 finisher version only) DATE: Apr. 15, ’94

PAGE: 3 of 3

Therefore, after the original feeding for the copy from the duplex tray is carried out, the original feeding for the copy from the normal paper tray is continuously done. Then original feeding pauses for one original. This process continues until the copy run completes. (The copying speed becomes 2/3 of normal copying speed.) If a paper end condition is detected, the copier stops feeding paper from the duplex tray and the paper end indicator appears in red letters. If the auto tray switching mode is selected and there is the same size paper in anther paper tray (except for the first paper tray because it is not selected by the auto tray switching), the paper tray is automatically switched and then the copying speed recovers to normal and the copy run will continue.

When the second or third paper tray is used, this slow down of the copying speed is not necessary. With the second and third paper trays approximately 50 sheets of paper remains even after the paper end condition is detected, due to the difference in the paper end detection mechanism from the first paper tray or LCT. Therefore, even when the paper end condition is detected during copying, the copier can stop feeding paper from the duplex tray after feeding one extra sheet of paper from the second or third paper tray.

Original Table

Vacuum Belt Unit

Bearing

Vacuum Belt Unit

It was found that the vacuum belts slightly overrun even after their drive force from the original feed motor is cut by the original feed magnetic clutch. Some originals at the bottom of the original stack are slightly transported by the vacuum belts while the other originals stay in the correct position on the original table due to the air knife air. During the continuous copy run, some originals at the bottom tend to feed-in together or the distance between two originals tends to become narrower, resulting in multiple-feeding or a jam.

SUBJECT: Modifications to minimize original jams DATE: Apr. 15, ’94

PAGE: 2 of 7

Logically, the vacuum air stops just before the vacuum belts stop. However, electrostatic charge generated on the vacuum belts attracts the bottom sheet of the original stack even after the vacuum air stops. (The electrostatic charge is easily generated when the vacuum belts are not cleaned for a long time. Also, cleaning the vacuum belts increases the friction force between the vacuum belts and vacuum belts unit surface and prevents the vacuum belts from overrunning.)

To increase the friction force to stop the vacuum belt after their drive is cut, replace the 4 ball bearings (Ball Bearing - 6 x 12 x 4 mm: P/N-07413506) with dry bearings (Bushing - 6 x 12 x 4 mm: P/N-A4221078) for the 2 belt drive rollers. (Remove the original table and then vacuum belt unit as shown in the illustration on previous page. The ball bearings can then be replaced.) This stops the vacuum belts immediately after their drive is cut. As this modification is very effective, it is recommended to replace the bearings for all field units. (The cut-in serial numbers for this modification will be informed by an MB.)

NGOK

NOTE: Monitor the condition of the original stack during original feeding. If the condition is

as shown in the illustration above (the right side), multiple-feeding or a jam will easily occur. Even after the modification mentioned above is done, this will occur if the originals are not suitable for the RDH mode. Especially if the originals curl as sown below (the right side), like originals made by a laser printer, this problem is likely. In this case, instruct the operator to make one set of copies of the originals and use them as the originals to set in the RDH.

Grounding Plate

When the originals are fed-out onto the original table, the trailing edge of the originals are sometimes caught by the grounding plates for the anti-static brushes (although this is very rare). In most cases, the original that is interfered with by the grounding plate returns to the original stack when next original is fed-out but it is stacked unevenly. When the original is fed from the original table the next time, multiple-feeding or a jam tends to occur.

To prevent this problem, move the grounding plates outward as shown above, so that they do not interfere with the A4 or 11" x 8

SADF Exit Gate

Resulting in a jam or skew

The SADF exit guide is made of plastic with embedded glass fibers. Therefore, due to part variation or when its surface wears out due to the repeated original transportation, the glass fibers make the surface coarse. When this occurs, the leading edge of the originals tends to be caught by the surface of the gate as shown above.

To prevent this problem, a sheet of mylar (Mylar - 442 x 21.3: P/N-A1127546) has been added on the gate. The part number of the gate has also been changed from A0287500 to A1127545 (Gate Plate) which includes the new mylar. (The cut-in serial numbers for this modification will be informed by an MB.) For the field units, be sure to install the mylar in the correct position as shown below.

4. To prevent original jams caused by electrostatic charge

Every 200K PM and at every visit, clean the exposure glass using glass cleaner or alcohol. Then, wipe with silicon oil. Also wipe the mylar strips on the original transport path.

Wiping the exposure glass and mylar strips with silicon oil helps transport originals more smoothly and prevents original jams caused by electrostatic charge that is generated due to the repeated original transportation. Note that the exposure glass must be replaced with new one when the glass surface resistance becomes too low and original jams caused by electrostatic charge tend to occur. (An electroconductive coating is used on the surface of the exposure glass to prevent electrostatic charge from being generated.)

ROMs on the operation ROM board, main board, and ADF control board have been changed as described below. Note that the 4 main control ROMs on the main board (M0, M1, M2, and M3) have been changed three times (Suffix B to C, Suffix C to D, then Suffix D to E).

• To detect double-feeds of the originals in the RDH mode, new software has been

added. For each cycle of original feeds while in the RDH mode, the number of the originals that have been fed-in is counted and compared with that of the previous cycle.

FROM: 2nd Technical Support Section

MODEL: F5 Finisher Version Only (Ricoh FT9101/ nashuatec 53101)

If the number of originals in the last and previous feed cycle does not match, the copier detects an abnormal condition. The original feed and copying is stopped immediately after the last original has been fed-in. (If A4 size originals are used, the last 3 originals do not return to the original table and are stopped inside the RDH.)

After the above, the copier displays the misfeed indicator for the copy paper feed station that was in use (location "A" or the 4th paper tray), although a real copy paper feed jam has not occurred.

This indication is unnecessary and unusual because the actual problem is that an original double-feed has occurred. However, to use existing software sequences for job recovery, this misfeed indication could not be removed. (We are still trying to develop new software to remove this indication, but it is not available yet.)

To reset the above condition of the copier, the front door of the copier must be opened then closed. (This is normal operation to reset the indicator for the copy paper misfeeds although no jammed paper will be found because the indicator was not due to a real copy paper misfeed.)

(The operating instructions will be changed to P/N-A112 8607A when the current operating instructions in stock are finished.)

CAUTION: When you install the new ROMs in the old type machine, if the speeds of the transport and reverse motors in the RDH are rather slow, an original double-feed might be detected and the copying is stopped without an actual original double-feed.

• With the U.S.A. version operation ROMs, values of the margins that are adjusted with

the Margin Adjustment mode are represented in inch size. With the old ROMs, the display for the Margin Adjustment mode is indicated in inch, but the actual adjustment values (margins) change only in millimeter size as follows:

Display (inch) 1/8 1/4 3/8 1/2 5/8 3/4 7/8 Actual Margin (mm) 1 2 3 4 5 6 7

• Therefore, with the old ROMs the actual margins made with the Margin Adjustment

mode are much smaller than those selected on the screen display. Also, the screen display is sometimes disordered due to mismatched signals between

the main and operation boards when a margin is selected. The 4 new operation ROMs have corrected this, and the margins will be made just as indicated on the screen display. (This problem was in the U.S.A. version operation ROMs only.)

2. Four Main Control ROMs on Main Board (Suffix C to D)

• When an odd number of originals is used with the RDH mode and 1 Sided Originals

To 2 Sided Copy mode, a few of copy counts of the mechanical total counter have been skipped. Also, when this occurs, SC99 (a control system error) is logged in service tool [3-07]. This has been corrected with the new ROMs.

3. Four Main Control ROMs on Main Board (Suffix D to E)

• In the RDH mode, when the number of the copies stacked in the duplex tray exceeds

80 for A4, 81/2"x13", or smaller size (the duplex tray capacity limit), copying pauses automatically. (The number of originals set in the RDH is limited to 80.) In the Stack mode with originals set in the RDH, up to 80 can be entered as a copy set number.

However, with the old ROMs, in the SADF or Platen mode, the number of the copies stacked in the duplex tray is not limited. Therefore, if the operator enters a number exceeding the maximum duplex tray capacity as a copy set number in the Duplex mode with the SADF or Platen mode, paper misfeeds will occur at the duplex paper feed station while the paper is being fed from the duplex tray for reverse side copying.

With the new ROMs, even in the SADF or Platen mode, a number exceeding the maximum duplex tray capacity cannot be entered as a copy set number. If such a copy set number is entered and the Start key is pressed, the beeper sounds and the number automatically changes to 80 (in the case of A4 size copy paper).

• The default setting for service tool [4-05] (Utility) has been changed. Mode number 2,

which was set at 10 (Utility 2-10: Duplex speed-up mode) with the old ROMs, has been set at 0 (nothing selected). If the user prefers the Duplex speed-up mode, you can set it.

• If one of the Finishing modes (Shift Tray ON mode, 1 Staple Upper mode, etc.) is

selected as a initial display with service tool [2-16], the Pre-heat function does not work even when "Valid Pre-heat key" is selected with utility 14-5-8 of service tool [4-05]. This has been corrected.

4. Two of the 10 ROMs (3E and 3O) on the Operation ROM Board

• The message "Check paper size." had a spelling mistake and it has been corrected.

("Peper" to "Paper".) (This message is displayed when the Start key is pressed and if there is no suitable size of copy paper when in APS mode.)

5. ADF Control Board ROM

• Very rarely, the recycle arm did not return onto the original stack at the end of an

original feed cycle and the original feed did not stop. This was found when B4 size originals were used and only while a job recovery motion for originals (with the low speed of the original feed). To correct this, the ROM has been changed.

• If an original misfeed at the exit area was detected when in the Exit Original To Tray

mode which was set with user tool 10, the misfeed condition could not be reset. This has been corrected.

• If an original was set in the SADF and the Start key was pressed soon after the

Pre-heat mode, which was set with utility 14-5-8, was released, the original was not fed-in. This has been corrected.

• The original feed test mode for the 2 Sided Original To 2 Sided Copy mode did not

CLEARING ORIGINAL MISFEEDS

Resetting Original Error Conditions

There are two kinds of original error conditions which must be reset in different ways.

1. Original misfeeds

When a misfeed occurs, the original misfeed display appears. The display indicates the position of the misfeed occurred and the unit or cover you should open to remove the misfed originals. For how to clear original misfeeds, refer to the operating instructions.

2. Original double-feeds

In Stack Original Feed mode, when the number of sheets in the last and previous copy sets does not match, a double-feed has occurred. The misfeed indicator for location "A" or the 4th paper tray will light. After you open and close the door or cover to reset the indicator, the message "Copies out of order. Copy again." appears in the display. Clear original double-feeds as follows.

Remarks

• Do not turn off the main switch when you clear the original double-feed condition.

• When original double-feeds occur, do not touch the originals in the

recirculating document handler until you reach step 4. The originals still inside the RDH need to be returned to the original table. The RDH will do this by itself. Before resuming the copy job, check the page order of the originals.

1. You will find the misfeed "A" or 4th paper tray indicator lit in the display.

• The misfeed indicator that will be lit in the display depends on the paper tray you use.

2. Open the door or cover indicated in the display. If you find misfed paper, this is an actual copy paper misfeed. Remove the paper referring the operating instructions.

3. If you cannot find misfed paper, close the door or cover to reset the misfeed indicator.

4. The Cancel key is displayed in the operation display. At the same time, the message "Copies out of order. Copy again." appears on the message area. Touch the Cancel key.

• The originals stopped inside the RDH will return to the original table. If there are

copies in the duplex tray, they will be fed out to the copy tray. Then, the copier will stop.

• After you touch the Cancel key, the copy set number you set at first will change to

the remaining number of copy sets. The copy set number that appears on the copy counter after copies are completed is the set number you first chose.

5. Check the delivered copies and remove the last set of copies delivered. You need to do this because the set includes copies in the wrong page order.

• Make sure to remove the last set of the copies made before you go on with the copy

job. The last copy set is a bad set, and if you do not remove it now, you’ll have trouble finding it later.

• The bad set is usually the last one. However, if the copier stops in the middle of the

2nd copy cycle, check the 1st copy set because the 1st copy set is the bad one, restart the copy job from the beginning.

• When you make copies in Finishing mode, the bad set will be delivered to the copy

tray. However, some sheets might already be on the way to the shift tray, so that you will have to remove these yourself.

• Check if the originals are in the correct order.

6. Press the Start key to resume the copy job.

• The copier will add a copy set to make the required number of sets.

Action Required Troubleshooting Retrofit Information

To detect double-feeds of originals in the RDH mode, the software has been changed. (Refer to RTB-020.) As a result, it was found that an original double-feed might be detected and the copying stops without an actual original double-feed if the speeds of the transport and reverse motors in the RDH are rather slow. (The recycle arm will be placed on the top of the original stack a certain period after the last original feeds out. If the feed-out of the last original is too late due to low speed of the motors and the next original feed-out signal comes on before the recycle arm operation, the recycle arm will not be energized. While the next original feed cycle, the number of originals that is fed does not match the number for the previous cycle and an original double-feed is detected.)

On the production line the speeds of the motors are adjusted with a special tool and they can be read in Hz, unlike the method in the field. The old adjustment standards were as follows:

Revision of service manual Information only Other

FROM: 2nd Technical Support Section

MODEL: F5 Finisher Version Only (Ricoh FT9101/ nashuatec 53101)

Transport motor speed: 3750 ± 112 Hz Reverse motor speed: 3600 ± 108 Hz

To prevent misdetection of original double-feeds, the adjustment standards have been changed as follows from the May 1994 production (the cut-in serial numbers are A3544050001 for the FT9101 and 6204050001 for the nashuatec 53101):

Transport motor speed: 3800 ±± 30 Hz Reverse motor speed: 3650 ±± 30 Hz

For the method of the motor speed adjustment in the field, the procedure using the three LED’s on the ADF control board (refer to "Adjusting the motor speed" in the field service manual) is still valid because a more exact motor speed can be obtained with the procedure than with the method used on the production line.

Therefore, if an original double-feed misdetection occurs, adjust the speeds of the transport and reverse motors according to the procedure mentioned in the field service manual. To obtain exact adjustment, also be sure to apply the following remarks (these remarks are valid also for the original feed motor adjustment):

• LED113 on the ADF control board can sometimes light but LED111 must not

light while adjusting the motor speeds. (LED112 must mostly light.)

• For a while turn on the RDH free run with the transport test mode or do an

actual copy run in the RDH mode, in order to stabilize the motor’s speed. Then, after stopping the operation, carry out the adjustment. (The motor’s speed varies if this is not done.)

PREPARED BY: H. Kokubo CHECKED BY: S. Hamano

CLASSIFICATION:

Action Required Troubleshooting Retrofit Information

To minimize original double-feeds, the following causes (CAUSE 1 to 3) and solutions (SOLUTION 1 to 3) have been found:

CAUSE 1

Original double-feeds may occur while making a large number of copy sets (during a long original recirculating motion).

When an original reaches the original feed roller (the first transport roller) from the original stack, the original stops and the original transport belts (the rubber belts) rub against the original because they are still turning. Static electricity is generated due to the friction.

Revision of service manual Information only Other

FROM: 2nd Technical Support Section

MODEL: F5 Finisher Version Only (Ricoh FT9101/ nashuatec 53101)

Then, when the original is transported further by the original feed roller and the trailing edge of the original feeds out from the bottom of the original stack, this static electricity is discharged against the leading edge of the originals on the table. While some originals are being fed, static electricity builds-up and the leading edges of the originals around the bottom of the stack stick to each other.

As a result of this, the air knife cannot separate the originals properly and original double-feeds tend to occur. (The number of originals, which can cause the heavy static electricity and double-feeds, varies depending on paper type of the originals.)

SOLUTION 1

To remove the static electricity before it is discharged against the originals on the table, an antistatic brush (P/N-A112 7984: Antistatic Brush - 180 mm) has been added to the entrance area from the August 1994 production.

Technical Bulletin No. RTB-023

SUBJECT: Original Double-feed Prevention DATE: Nov. 15, ’94

PAGE: 2 of 6

CAUSE 2

The number of the originals set in the RDH affects the original feed ability. When the originals are few, friction between the originals is small due to the light weight of the stack. The air knife can stop the second original, preventing it from being transported with the bottom original. However, when the originals are many, friction between originals is large. As friction between the bottom and second originals is also large, the second original cannot be stopped only by the air knife and it tends to be transported with the bottom original.

When the weight of originals is sufficient, the second original (and the following originals) is stopped not only by the air knife, but also by the friction between the second and third originals (and the following originals). Friction between the bottom and second originals is much smaller than that between the following originals, and only the bottom original can be fed.

The air knife volume tends not to be satisfactory when the number of the originals on the table is around 20 to 30. For around these numbers of originals, the air knife volume is too low (the original stack is too heavy) to stop the second and the following originals. Otherwise, the volume is too high, and friction between the second and the following originals becomes too low (as compared with that between the bottom and second originals) due to the strong air flow.

To allow the wide range of the original set capacity, there are two levels for the air knife HIGH and LOW. (The volume is determined based on the position of the recycle arm when it is placed on the top of the original stack. If the adjustment is not correct and the air knife volume does not match the weight of the original stack on the table, original double-feeds or misfeeds will occur.) Even if HIGH or LOW of the air knife is selected, for around 20 to 30 originals, the air volume tends not to be satisfactory and original double-feeds tend to occur.

SOLUTION 2

To enable feeding of the bottom original only, a mylar sheet (P/N-A112 7871: Mylar Sheet

- 183 x 22.5) will be added from around November 1994 production. (The cut-in serial numbers will be informed by an MB.) The original entrance will be limited at 8 mm in height (between the bottom of the original table and edge of the mylar sheet). Even if some originals are fed-in together, the mylar sheet can stop next originals and the bottom original only passes the entrance. (If some originals are stuck together because of electrostatic, heavy curl, or any other reasons, such originals can still pass the entrance and cause a double-feed.)

NOTE: If the entrance is too narrow (less than 8 mm), the leading edge of the bottom original will be caught by the mylar sheet, causing a jam, especially when the original is curled.

SUBJECT: Original Double-feed Prevention DATE: Nov. 15, ’94

PAGE: 3 of 6

This mylar sheet also shuts in the air knife blowing against the upper part of the original stack. This prevents friction between the originals from becoming too small because of too strong air flow.

Another purpose of this mylar sheet is to ensure the life time of the antistatic brush indicated in SOLUTION 1. Without this mylar, fibers of the antistatic brush rapidly break due to vibration of the fibers caused by the air knife. The mylar sheet can minimize the vibration.

CAUSE 3

The antistatic brushes at the original exit wear out after approximately 1,000,000 originals are fed. While originals are passing the antistatic brushes, their fibers are bent strongly because the fibers are too long. After the long usage, the fibers break.

If the antistatic brushes at the original exit wear out, static electricity remains on the originals fed out onto the original stack. This will cause original double-feeds or misfeeds.

SOLUTION 3

OLD

NEW

To lengthen the life time of the antistatic brushes, they will be changed to new ones, which have shorter fibers, from around November 1994 production. (The cut-in serial numbers will be informed by an MB.) To ensure the ability to discharge static electricity, the new antistatic brushes have more fiber density.
