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.)

Functions Exit Tray Copy

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.

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.)

On the production line, it was found that the dc main harness was damaged. The harness, which runs behind the 2nd paper tray, is cut as shown below when the 2nd

paper tray is slid in. If the harness is not run in the chamber properly and has slack, part

of the harness may come out the chamber and be damaged. The harness is fitted in the chamber and secured with two bindings. However, this is not

sufficient because of variation in production. Since October 1992, this part has been significantly checked during production to take away the slack in the harness.

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.

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).

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.
