SYMPTOM

1. False Bk toner end detection during developer initialization

2. Developer setup error code 511 during developer initialization

CAUSE

1. The toner supply motor gear [A] and toner supply gear [B] were not properly engaged. This caused the toner to be not supplied. The toner supply motor may have been incorrectly positioned and then secured in this position during the production stage. In such a case, either the motor gear [A] did not touch the toner supply gear [B] and/or the gears were engaged too tightly, causing the gear shafts [C] to bend.

2. The toner supply gear [B] was broken. When the drawer unit is inserted in the machine with the development unit located at the development position, the toner supply gear [B] contacts the motor gear [A]. This may cause the gear [B] to be broken.

Part information Electrical Transmit/receive

Date:

15-Jul-99

Prepared by: T. Itoh

No.:

RA258009

Action required Service manual revision Retrofit information

SYMPTOM

In solid areas, dark spots appear as shown in the illustration.

CAUSE

• The electrical resistance of the image transfer belt has a specified tolerance. If the

electrical resistance is in the lower area of the specification, the pre-fixed transfer bias becomes higher than the optimum value. In this case, toner transferred onto the belt tends to be re-attracted to the drum.

• Small carrier particles in the development unit tend to be physically attracted to the

drum. The carriers transferred onto the belt create a gap between drum and belt. Toner on some parts of the transfer belt where the carriers are transferred are not re-attracted to the drum due to the gap. The result is dark spots in solid areas as shown above.

• It is known that the dark spots problem tends to appear as the development potential

becomes higher. If the residual voltage detected by the drum potential sensor is 30V or less, the potential sensor is damaged and this may cause the dark spots.

SOLUTION

1. Check the residual voltage with SP3-111-00. If the voltage is 30V or less, replace the

drum potential sensor and check whether or not the problem disappears. If not, see step 2.

2. Decrease the transfer belt bias with SP mode as shown below.

SYMPTOM

1. Blank I mage or Vertic al Li nes

2. SC326

NOTE:

This problem occurs in copy or scanning mode only. It does not occur during print jobs.

CAUSE

Normally, the input pins (#12 to 17) of IC18 on the BUSSW board are not used for the function of the IC18. However, due to an error in the software programmed in IC18, these pins were allocated as output pins. The resulting increase in power consumption causes the IC to heat up and malfunction.

NOTE:

1. Blank I mage or Vertic al Li nes When the IC does not renew the scanned image data due to the cause explained above,

blank image or vertical lines appear on the outputs depending on the image of the first line scanned in.

2. SC326

After analysis and testing of the PCBs returned from the field, it was found that the cause explained above was a majority of the causes. The other causes are isolated cases.

• If the first line scanned in is blank, the output is blank.

• If the first line scanned in contains an image, the output will contain vertical lines.

When the IC does not send the LSYNC signal to the ASIC, the FGATE signal cannot be generated (causing SC326).

If the problem is related to IC18, the replaced (old) PCB can be re-used after cutting pins #12 - 17. If occurrences still continue after cutting the pins, the problem is being caused by another PCB component.

If the BUSSW board (IC18) causes the problem and the part is not available, cutting the pins (#12 - 17) of IC18 as explained in section [2] on page 5 of this RTB solves the problem.

2. SC326

NOTE:

This problem occurs in copy or scanning mode only. It does not occur during print jobs.

CAUSE

NOTE:

1. Blank I mage or Vertic al Li nes When the IC does not renew the scanned image data due to the cause explained above,

blank image or vertical lines appear on the outputs depending on the image of the first line scanned in.

2. SC326

After analysis and testing of the PCBs returned from the field, it was found that the cause explained above was a majority of the causes. The other causes are isolated cases.

If the first line scanned in is blank, the output is blank.

If the first line scanned in contains an image, the output will contain vertical lines.

When the IC does not send the LSYNC signal to the ASIC, the FGATE signal cannot be generated (causing SC326).

If the pitches are not clearly visible and it is difficult to judge whether the width is 6 or 8 mm, check if the banding disappears or is improved by disconnecting the connector [C] of the paper separation corona.

If the banding disappears or is improved, it is 8-mm banding.

If nothing is changed, it is 6-mm banding.

Disconnecting the connector of the paper separation corona itself is not expected to cause paper jams. However, please use a recommended type of paper if available. After the test is finished, make sure that the connector is re-connected properly.

CAUSE

The charge corona fan stays on while the main switch is on. Since the charge corona fan draws the air into the machine, the charge corona unit becomes dirty due to dust in the air. The problem occurrence depends on the environmental conditions where the machine is installed.

This problem has been reported only from the Ja panese market, so far. The problem occurred especially in environments where a humidifier (supersonic wave type) was used. A substance left after moisture evaporates adheres to the charge corona unit, causing this problem.

SOLUTION

As a solution to this problem, two modifications have been applied. One involves SP mode and the other is a grid cleaning pad. There are notes on how to apply the solution to the field machines depending on the environment and/or the condition of the machine. Please investigate which solution (either or both) should be applied.

Solution [1]: SP Mode

The software has been modified and the following SP mode was added.

Description

Specifies the off timing of the charge corona fan.

When SP3-980-00 is set to “1”, the fan turns off 30 seconds after the drum motor stops or when Energy Saver mode turns on. (The fan turns on again when the drum motor turns on or when Energy Saver mode turns off.) This SP mode can extend the time until the charge corona unit is considered dirty.

In addition to the SP mode, a grid cleaning pad (#A2592311) has been added to the upper frame of the drum unit (as shown in the picture) from the June production run onward. (Please refer to MB #18 for the Iris and #15 for the Lilac for the cut-in serial number.)

This modification enables service technicians or users to clean the grid plate. Please use this pad if the problem is reported.

NOTE:

The grid cleaning pad tends to be worn away while cleaning the grid plate, and needs to be replaced after being used for cleaning around 100 times. Although this is a consumable part in this case, this part is not assigned as a PM part since the problem occurrence is very rare.

SYMPTOM

A squeaking noise is generated in the development unit.

CAUSE

The vibration generated from the doctor blade during the development process is transferred to the upper cover. This results in a squeaking noise.

SOLUTION

To absorb the vibration, four foam rubber pads have been attached to the development cover. If the squeaking noise occurs in the field machines, please follow the procedure described below. Please refer to MB #22 (Iris) and #19 (Lilac) for the cut-in serial number information.

1. Make a full color copy and check when

the noise occurs (i.e. at which color in the development process).

2. Turn off the main switch.

3. Pull out the drawer unit.

4. Remove the drum unit and place a few

sheets of paper on the unit to prevent the drum from developing light fatigue.

5. Remove the relevant development

unit(s).

6. Remove the development cover [A] (3

SYMPTOM

Paper jam at the by-pass tray.

CAUSE

Even if the user selects ‘sideways’ with the operation panel, the paper orientation is automatically reset to ‘lengthwise’ if the by-pass tray side fences are moved to the 12” size position. This may result in a paper jam.

SOLUTION

A stopper has been added to the front side fence so that the maximum width that can be set is A3 (11”). This stopper can be pulled out to make copies with paper larger than this size.

• Please refer to MBs, which will be issued soon, for the cut-in serial number.

• An errata sheet (see the next page) has been enclosed with the modified production

Please note the remarks explained below when installing the transfer belt stay [A].

REMARKS:

Install the transfer belt stay [A] while pressing portion [B]. The transfer belt unit will then be secured in the proper position by the pressure from spring [C]. If portion [B] is not pressed while the screws are fastened, the transfer belt stay will not be fixed in the proper position due to the pressure from the spring. This will cause the PG (photoconductor gap) to shift slightly.

Although a slightly shifted PG would not directly cause any machine failure, a proper PG is essential to ensure the effectiveness of measures such as troubleshooting for black toner scattering (PG seals). Please be sure to follow the above procedure when installing the transfer belt stay.

SYMPTOM

Toner spills out from the joint section [A] of the toner collection coil, and the interior of the machine at the rear becomes dirty with toner. This can cause toner spots on copies or paper jams if toner drops onto the clutches.

CAUSE

Used toner tends to lump together due to the temperature of the toner collection coil. The toner then gets clogged around the joint section. This can cause toner to spill out from the joint section.

SOLUTION

• The material of the toner collection coil has been changed from plastic to metal. This

will prevent the temperature of the coil from rising. This modification was applied to the production line in July ’99. Please refer to MB #05 (Iris) and #02 (Lilac) for the cut-in serial numbers. At the same time, in order to force the toner to drop straight down into the collection coil tube, the size of cutout [B] in the toner outlet cap has been changed as shown below.

• A seal has been added to the drawer unit to cover the joint section. This was applied to

the production line in February 2000. Please refer to MB #29 (Iris) and #25 (Lilac) for the cut-in serial numbers.

If this problem occurs in the field, please replace the toner collection coil and toner outlet cap, and attach the seal.

SYMPTOM

Black toner scatters inside the machine. Toner accumulates around the black development unit and ID sensor areas, which can sometimes cause SC385.

CAUSE

If the PG (photoconductor gap) is close to the upper limit, toner concentration tends to increase and toner may scatter inside the machine. When toner accumulates on the ID sensor, this may cause SC385.

This occurs most often with black toner due to its unique characteristics.

SOLUTION

Production line

• In order to shift the PG, a PG seal (#A2593219) has been attached to the lower

development unit holder of the black development unit only. Please refer to MB #27 for Iris and #23 for Lilac.

NOTE: Please do not attach the PG seals for the color development units. If this is done,

a color band may appear on the outputs. This is because the narrow PG may cause the developer sleeve of a color development unit to touch the drum surface when the unit moves into the development position.

• The dust filter has been modified twice to minimize the amount of dust exiting the

machine. For the first modification, refer to MB #21 (Iris) and #18 (Lilac). For the second, refer to MB #28 (Iris) and #24 (Lilac).

• The ID sensor cover has been modified to optimize the airflow to the ID sensor. This

prevents toner from accumulating on the surface of the ID sensor. Please refer to MB #32 (Iris) and #28 (Lilac).

• The drum shaft supporter has been modified and an additional ball bearing has been

inserted in order to prevent the PG from changing during copy runs. Please refer to MB #34 (Iris) and #30 (Lilac).

• The development unit holder has been modified twice. The first modification was done

to improve the holder durability and the second was done to ensure the proper PG. Please refer to MB #33 (Iris) and #29 (Lilac).

1. Pull out the drawer unit.

2. Remove the drum unit and place a few sheets of paper on the unit to prevent the drum from developing light fatigue.

3. Clean the machine using a vacuum cleaner.

4. Remove the black development unit.

5. Clean the lower development unit holder [A] completely with damp and dry cloths.

NOTE: For damp cloths, use water and not alcohol. Alcohol can deform the seal. If alcohol

is used by accident, clean the holder with a dry cloth after the holder dries.

6. Attach a PG seal [B] to both sides of the lower development unit holder as shown.

NOTE: Make sure that the seal has been attached flush against the holder and is not

folded. If the seal is not properly attached, the PG will be out of specification.

The PG seal should not be attached to the development holders for other colors. If this is done, the PG will become narrow and the developer brush may contact the drum while the revolver rotates. This causes a color band to appear on the outputs.

- This version of the main firmware has been used from the first unit of mass production.

1 Allows the counter method to be changed (copy or development counter)

only once in SP mode (SP7-008-000).

1 The transfer belt bias has been optimized as follows:

SP Mode Number Current value New value SP2-301-013 800V 1000V SP2-301-014 900V 1100V SP2-301-015 1000V 1200V SP2-301-016 1100V 1300V SP2-301-019 800V 1100V SP2-301-020 900V 1200V SP2-301-021 1000V 1300V

2 The following problem has been fixed:

In a certain situation, the last original may not be fed out from the ARDF in 1 to 1 mode.

1 To prevent Toner End from being detected by mistake for black toner, the

detection parameter has been changed from 4 to 8 times. The display for the counters has been changed. “Copies” or “Developments”

is displayed on the panel, depending on the counter method selected. This allows us to clearly know which counter method has been selected.

2 Symptom

Horizontal white lines / dirty background at the trailing edge when copying onto transparencies. This occurs in all environmental conditions except high temperature and humidity. Solution The default setting of the following SP mode has been changed and the AC component of the paper separation corona turns ON when copying onto transparencies.

6 The following problem was corrected:

The logging data (SP7-809-01) was not counted properly.

1 The following problem was fixed:

An area of up to 20 mm from the trailing edge of the last copy becomes lighter in OHP or Thick Paper mode under the following conditions:

• Selected paper size is A4(LT) sideways or smaller

• The amount of copies selected is an even number.

2 The following problem was fixed:

In Series copy mode (Book to one-sided), halftone areas on the right side of originals come out lighter under the following conditions.

• Black-and-white copy mode

• The number of copies selected is 3 or more.

3 After a job is finished, the Start Key will turn green sooner. 1 This firmware can support the coin-lock system.

NOTE:

It is not possible to use both the coin-lock system and User Code mode at the same time.

1 A blank display problem found in the previous version has been corrected. 2 To prevent by-pass tray jams when feeding the reverse side of the paper,

the pick-up roller OFF timing has been changed. With this modification, the pick-up roller continues to feed the paper until the paper reaches the grip roller.

Refer to RTB #017 for the details.

Do not use this version in the field. This

firmware causes the control panel of the controller to appear blank.

Version Modifications Remarks

7.02

1 The software has been modified for the following reasons:

• To minimize dirty background in normal paper copy/print modes

• To minimize dirty background in OHP/thick paper copy/print modes

• To prevent horizontal color bands in color copy/print modes

- Contents of modification -

(1) Dirty background

The development unit will stay at the development position under the following conditions:

• When the OPC drum starts rotating to develop the latent image.

• During the extra transfer belt rotation (see the note below) in Thick/OHP

mode (copy/print).

To prevent toner from being attracted to the drum, a development bias is applied to the development sleeve. However, the dirty background becomes worse if the drum and/or developer have deteriorated. To minimize dirty background, the timing of the revolver rotation and the position of the development unit have been changed.

Note:

In Thick Paper/OHP Modes, the process speed is reduced by half after the image is developed on the transfer belt (4-color image for full color). To properly transfer the image developed on the transfer belt onto the sheet of paper, the transfer belt makes an extra rotation.

7.04

7.05

(2) Horizontal color band

To improve image quality, the PG was slightly reduced from March ’00 production. However, when the PG is reduced, the developer brush tends to touch the drum surface while the revolver rotates. This may result in a horizontal color band on the outputs. To prevent this band, the timing of the revolver rotation has been changed so that the color band will not be transferred to the image area of the transfer belt.

2 The SP modes listed below have been added so that toner concentration

can be adjusted with more precision and finer control.

New SP modes: SP2-203-001 to 013 and SP2-204-001 to 012

(Please refer to Appendix 1 for details).

3 The software has been changed so that the key counter counts twice for

A3/DLT when SP5-104-000 is activated (A3/DLT Double Count).

1 To prevent any data changes due to electrical noise, the initialization method

of the NVRAM has been changed.

1 “Charge Corona Fan ON/OFF” has been added to SP mode (refer to RTB

RA258017 for details). However, since turning off the fan can cause the temperature inside machine to increase, setting “2” below (bold) has been newly added to the software.

0: Stays on 1: Turn off 2: Turn on at 30 * using the temp. measured by the temp/humidity sensor

Version Modifications Remarks

2 If the machine is continuously on, the machine will not do the initial process

control self-check, causing the toner concentration to be out of range. To achieve optimum image quality under this condition, the software has been changed so that the initial process control self check will be done if both of the following conditions are met:

• 12 hours has passed since the last initial process control or forced

process control self-check and

• 1 hour has passed since the last timed process control self-check.

3 When the revolver rotates, a small amount of toner can flow into the

development unit, causing the toner concentration to increase. During the initial process control self-check, the machine automatically corrects the toner concentration (Toner Density Auto Control); however, this does not happen unless the main switch is turned off and on. To work around this, the software has been modified so that the toner density auto control can be done during the interval process control self-check. The corresponding setting (2) has been added to SP3-128:

SP3-128 Toner Density Auto Control

Setting (Default : 0) 0: Execute at initial and forced process control self-check 1: Not execute at any self-check 2: Execute at initial, forced, and interval process control self-check

The following SP modes have been newly added for Toner Density Auto Control:

SP3-130: TD Auto Correction Setting Specifies the number of copies to consume toner for the toner density correction of the initial or interval process control self-check. NOTE: Normally, it is not necessary to adjust this SP mode in the field.

[Adjustable range / Default /Step] SP3-130-001 Initial self-check [0 to 50 copies / 10 / 1 step] SP3-130-002 Interval self-check [0 to 50 copies/ 5 /1 step] SP3-130-003 Table limit setting [0 or 1 / 0 ]

The display for the counters has been changed. “Copies” or “Developments”

1.728

is displayed on the panel, depending on the counter method selected. This allows us to clearly know which counter method has been selected.

2 The development bias OFF timing has been optimized to prevent the

following problem: Poor image transfer may happen at the trailing edge of the last sheet of even pages in multi-copy mode (double image processing) with thick paper or transparencies.

3 The outline length of the closed loop area is extended as follows.

Before Modification Total Maximum length: Up to about 2 m After modification Total maximum length: Up to about 40 m Multi-closed loop: Up to about 10 m Closed loop for 1 area: Up to about 2 m

4 “Area editing” and “Auto Reduce/Enlarge (ARE)” can be selected at the

same time.

- When selecting Save Area mode -

• The saved area will be enlarged/reduced to fit the designated paper

size.

• The saved area image is aligned at the top left corner of outputs.

• The Centering function is selectable.

- When not selecting Save Area mode Since the image area becomes A3/DLT in “Area Editing” and “ARE”, the magnification ratio is automatically calculated based on A3/DLT size regardless of the original size. The magnification ratio must be selected manually if you want to specify the magnification for the designated paper size.

5 The following problem was corrected.

1.734

1.735

The printer gamma data for the printer mode, which is changed in SP mode, will not be applied to the copier until the main switch is turned off and on.

1 The following problem found in the previous version (Ver. 1.728) was

corrected.

The screen did not display magnification ratios greater than 255% even though the machine correctly made copies at these ratios.

2 The detection timing for the SC522 and SC524 error conditions was

optimized. SC522: Duplex - Side fence jogger H.P. error SC524: Duplex - End fence jogger H.P. error

3 The following problem was corrected.

Under the following conditions, the machine displays “Copy size cannot be changed“ on the screen after the paper is stacked in the duplex unit.

• Duplex copying in the platen mode from the by-pass tray.

• Paper on the by-pass tray runs out (paper end condition)

1 To prevent by-pass tray jams when feeding the reverse side of the paper,

the pick-up roller OFF timing has been changed. With this modification, the pick-up roller continues to feed the paper until the paper reaches the grip roller.

1 The software has been modified for the following reasons:

• To minimize dirty background in normal paper copy/print modes

• To minimize dirty background in OHP/thick paper copy/print modes

• To prevent horizontal color bands in color copy/print modes

- Contents of modification -

(1) Dirty background

The development unit will stay at the development position under the following conditions:

• When the OPC drum starts rotating to develop the latent image.

• During the extra transfer belt rotation (see the note below) in Thick/OHP

mode (copy/print).

To prevent toner from being attracted to the drum, a development bias is applied to the development sleeve. However, the dirty background becomes worse if the drum and/or developer have deteriorated. To minimize the dirty background, the timing of the revolver rotation and the position of the development unit have been changed.

(2) Horizontal color band

To improve image quality, the PG was slightly reduced from the March ’00 production. However, when the PG is reduced, the developer brush tends to touch the drum surface while the revolver rotates. This may result in a horizontal color band on the outputs. To prevent this band, the timing of the revolver rotation has been changed so that the color band will not be transferred to the image area of the transfer belt.

2 The SP modes listed below have been added so that toner concentration

can be adjusted with more precision and finer control.

New SP modes: SP2-203-001 to 013 and SP2-204-001 to 012

(Please refer to Appendix 1 for details).

3 The software has been changed so that the key counter counts twice for

A3/DLT when SP5-104-000 is activated (A3/DLT Double Count).

1 To prevent any data changes due to electrical noise, the initialization method

of the NVRAM has been changed.

1 “Charge Corona Fan ON/OFF” has been added to SP mode (refer to RTB

RA258017 for details). However, since turning off the fan can cause the temperature inside machine to increase, setting “2” below (bold) has been newly added to the software.

0: Stays on 1: Turn off 2: Turn on at 30 * using the temp. measured by the temp/humidity sensor

C, turn off at 26oC

2 If the machine is continuously on, the machine will not do the initial process

• 12 hours has passed since the last initial process control or forced

process control self-check and

• 1 hour has passed since the last timed process control self-check.

SP3-128 Toner Density Auto Control

Setting (Default : 0) 0: Execute at initial and forced process control self-check 1: Not execute at any self-check 2: Execute at initial, forced, and interval process control self-check

The following SP modes have been newly added for Toner Density Auto Control:

0: Limit, 1: No limit

1 During multi copy runs, the duplex feed motor malfunctions if the control

pulse is not generated when the interrupt pulse is generated. This causes a paper jam in the duplex unit.

- This version of scanner firmware has been implemented from the first unit of mass production.

1 Mono-colored thick lines in an original comprised of two or more toner colors

appear separated as two offset lines. This is due to the vibration of the scanner, which causes the scanner to detect a line in different positions each time it makes a scanning pass. The default setting for Auto Text/Photo Sensitivity has been shifted toward Text by 1 step.

2 The firmware for the Lilac Edit version can be installed in the Lilac Basic and

Iris versions, and vice versa. If this is done, SC150 is displayed when the main switch is turned on. The firmware has been modified so that SC150 is displayed before the data is stored in the flash ROM.

SYMPTOM

Noise from the toner collection pipe

CAUSE

The two drive gears (A1093631 x 2) are not properly engaged. This is because sometimes the side to side movement of the drive shaft in the bracket is not smooth enough.

SOLUTION

For action in the field, add 2 washers (08074025) between the gear and snap ring when changing the gear (see the illustration).

The surface of the drive shaft has been made smoother and grease has been applied to the drive shaft from August 2000 production.
