Check and replace charge roller

Do you mean the photoconductor unit? To replace the photoconductor (PCU), open the front cover and the right side covers (the duplex door and the main side door). The PCU sits to the right of the toner bottle -- it is a black unit that has the blue cylindrical drum facing the right side of the copier.

On the upper left side of this unit is a ridged tab. Push this tab in and slide the PCU all the way out of the machine. Open the box with the new PCU and remove all of the tape and paper, then slide the new PCU in where the old one came out of. When you shut all of the covers, the copier will recognize the new PCU.

SC481
Transfer belt mark detection error
• The main motor is operating; and
the lock signal is detected. → The
belt mark sensor signal does not
change for 120 milliseconds.
• Defective main motor
• Image transfer belt out of position
• Belt mark blurred or absent

I would remove the pcu unit (3 screws)and check the transfer assy belt mark and clean the sensor that reads the belt mark. Worst case senerio is replaceing the entire pcu unit.

sc 541=Heating roller thermistor error (Fusing unit).
The thermistors could be dirty or damaged.
The fusing unit can be removed and inspected(without removing any screws)(Left door)(lower handle).
If you see any damage you might have to replace the unit(or only the part if u r lucky).

replace the PCU (photo conductor unit)

sc541 is a fusing unit error code. Can you reset the code in service mode?

Hi there the following is the description from the service manual hope this helps you Thanks J

441 PCU (CMY) motor error
The drive motor of the CMY
PCU is not locked.
• Defective gear
• Voltage between pins 2 and 14 (CN12 on engine
control board) abnormal (not +24V), or pin 12
(CN12 on engine control board) unable to send
motor clock
• Defective CMY PCU drive motor
1. Replace the CMY PCU.
2. Replace the engine control board.
3. Replace the main drive unit assembly.

I would try replacing the CMY PCU (Drums (Photo Conductor Units) first before any of the others.

Thanks J
