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.

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.
shown in the above table. Then, check whether the dark spots have disappeared
completely or partially. If the dark spots are still present on the cop y, decrease the bias
again as shown and check the results.
become rough or light since there will be less toner transferred onto the belt and/o r it
may cause firefly spots due to a small amount of clogged toner that causes a gap
between drum and belt. When the belt bias is decreased, check the level of both the
dark spots and rough image/firefly spots. Select the proper bias that gives the best
overall results.

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.

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).

SOLUTION
On the production line
The BUSSW board has been modified twice as shown below. The boards thought to be
causing the problem are #A8485108. The problem does not occur with the Interface Kits
containing #A8485105 or #A8485112, as these boards do not use IC18.

- Additional Information – Modification As shown in the picture, there are two
types of BUSSW board (P/N #A8485108).
Type 1 is the board on which an IC [A] has
been manually soldered. Type 2 contains
an IC18 soldered onto the circuit pattern
by machine.

Type 2
Type 1 is the board that was modified in
the production (from #A8485 105). This
board contains one of the two ICs as
shown in the picture to the right [A]. The
only difference is in the size.
The function of the additional IC and IC18
is exactly the same. IC18 is soldered onto
the reverse side of the Type 2 board.

NOTE:
IC18 was added to the PCB for both
Japanese and overseas versions
since the board was used for all
machines.
The same PCB was used for Japanese
and overseas versions (with IC18
installed). However, since only the
Japanese versions actually use IC18, it
was removed from the overseas
versions. The board for all overseas
versions has then been given a new
part number.
- Additional Information – Cut-in Serial Number #A8485105 has been modified to #A8485108 by soldering an IC onto the board as
explained. This special modification was not controlled at the factory. Therefore, it is not
possible to specify the exact serial numbers of the I/F units that contain the modified
board. The table below contains our estimation of the serial number. The modification was
applied to a total of 112 boards, which means that 112 of the following 159 I/F units may
contain modified boards.

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.

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.

SYMPTOM
Curved dark bands [A] or uneven image
density appears due to a dirty charge
corona unit.
[A]
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.
NOTE:
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.

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.

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

NOTE:
When SP-5-104-000 (A3/DLT double count) is set to 1 (double count), the mechanical total

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
screws).
7. With damp and dry cloths, clean the
areas on the front and reverse sides of

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
units. An English version is enclosed with North American models and 5 languages are
enclosed with Europe/Asia models.

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.
Toner scatters around the toner hopper area and inside the machine.
CAUSE
The toner hopper seal is damaged or peeled off while the toner bottle is replaced. Toner
spills out from the gap between the toner hopper seal and the toner supply opening of the
toner bottle.
SOLUTION
Protective sheets [A] have been added to the toner hopper seals [B], in order to prevent
the toner hopper seal from being damaged while the toner bottle is replaced.

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).

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.

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.
3After a job is finished, the Start Key will turn green sooner.
1This 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.
1A blank display problem found in the previous version has been corrected.
2To 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

1The 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.
2The 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).
3The software has been changed so that the key counter counts twice for
A3/DLT when SP5-104-000 is activated (A3/DLT Double Count).
1To 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.

VersionModificationsRemarks
2If 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.
3When 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

is displayed on the panel, depending on the counter method selected.
This allows us to clearly know which counter method has been selected.
2The 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.
3The 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.
5The 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.
1The 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.
2The 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
3The 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)
1To 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.

1The 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.
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.

RA258026

(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.
2The 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).
3The software has been changed so that the key counter counts twice for
A3/DLT when SP5-104-000 is activated (A3/DLT Double Count).
1To 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
o
C, turn off at 26oC
2If 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 ]
0: Limit, 1: No limit
1During 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.
Date:
13-Oct-00
No.:
RA258026
This problem was found during internal tests. The paper jam occurred at
about 1,500 duplex copies.

-This version of scanner firmware has been implemented from the first unit of
mass production.
1Mono-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.
2The 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.
1 The following problem has been fixed.
SC326 occurs under the following conditions:
• A4 lengthwise

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.
