If the machine is A259 or A260, skip the remainder of this step.
For A258 machines, use SP7-801-000 to confirm that the firmware version of
the main control board is v.6.43 or later. If it is not, the copier's firmware must
be upgraded (to allow the controller connection).
26. Change SP3-125-000 from 0 (Default) to 2.
27. Enter SP3-126-000 then:

• The sensor is very sensitive. Do not drop the sensor or subject the probe [A] to shock
in any way. Please handle it carefully.
• The service manual shows that the setting powder is applied to the drum in the drum
unit. If the powder goes into the sensor through the window [B] or accumulates around
the window, it may cause the sensor to detect the potential incorrectly. Therefore,
please apply the setting powder to the drum before the drum is placed in the drum unit.
• If the potential sensor is not installed correctly in the drum unit, an error such as 20*,

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.

the drum. Insert the drawer unit.
When installing machines produced in February and
March, check whether the toner supply motor is properly
positioned after the drawer unit is pulled out and make
sure that the plastic part (black) [A] is correctly placed in
the cutout in the rear frame. (Please refer to the picture
below this table.)
If the motor is not correctly positioned, remove the
motor.
If the gears on the motor shaft are properly engaged,
•
reposition the motor in the cutout properly.
If the gears on the motor shaft are not properly
•
engaged or the shafts have already been bent,
replace the motor.

below.
1. Remove the toner bottle.
2. Pull out the drawer unit.
3. Remove the damaged seal and clean the
surface of the toner hopper where the seal is

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).

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.

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.
The action described on the following pages is required on the field machines equipped
with the Interface Kits containing #A8485108. The serial numbers of these Interface Kits
are listed on the next page.

[1] Troubleshoot as shown below when the problem is reported.
Start
In which mode problem
occurs?
Copy or Scan
Regardless of
mode selected
Check the connectors from I/F
kit is properly set to copier.
Printing an internal pattern in
SP 5-955 may specify a cause
of the problem. If the problem
does not occur, this may be
caused by poor connection of
connectors.

described in SC CODE
section of S/M (page 9).
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.

1. Turn off the main switch and unplug the power cord.
2. Disconnect the cable(s) from the controller.
3. Remove the exterior covers (used toner cover and I/F unit cover).
4. Remove the controller from the I/F unit (6 screws).
5. Remove the cover plate [A] (2 screws).
6. Remove the AC drive board [B] (4 screws and 2 connectors).
7. Remove the shielding plate [C].
8. Replace the BUSSW board [D] (4 screws, 1 grounding screw, and 2 connectors).

1. Remove the BUSSW board by following the procedure described on the previous page.
2. Using small cutting pliers, cut pins #12 to 17 so that they do not touch other pins or
patterns. This will prevent a short circuit.
3. Remove the cut pins from the board surface.
NOTE:
Be careful not to damage the PCB pattern or cut other pins. If pins #11 or 18 are
cut, this will cause SC326.

It was reported that connector 408 [A] on the IPU board breaks easily during servicing. It
seems to happen when the connector is opened by hand (e.g. using the forefinger or index
finger). Please make note of the remarks below and keep this point in mind when
accessing the IPU board.
Remarks
Open the connector carefully by using a small-blade screwdriver. (See the photo 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).
