To A Microswitch Pcb Failure - Canon iR C3200 Series Service Manual

Items to Check
1) In service mode level 1 COPIER > FUNCTION > PART-CHK > MTR, enter 1 and press the OK key.
2) In service mode level 1 COPIER > FUNCTION > PART-CHK > MTR-ON, press the OK key to check
whether the motor is working normally.
3) Check whether 24V is supplied to J93 on the ITB drum motor. If yes, the ITB motor likely faulty.
4) If 24V is not supplied to the ITB drum motor, check whether 24V is output from fuse PCB J70-3 to the ITB
drum motor.
Also, check whether 24V is output from the fuse PCB J71-1 to the microswitch PCB and also whether 24V is
supplied to the fuse PCB J71-2 from the microswitch PCB.
5) If there is no problem between the fuse PCB J71-1, -2 and the microswitch PCB, the fuse PCB is likely faulty.
If 24V is output from the fuse PCB J71-1 to the microswitch PCB and not supplied to the fuse PCB J71-2, check
the microswitch PCB.
Field Remedy
Replace the drum ITB motor.
DC Brushless Motor Part No. FH6-1971-000
16.3.10.13 E012-0001 Error code At about 37 sec. after the power is turned ON,
due to a microswitch PCB failure
Symptom
About 37 sec. after the power is turned ON, E012-0001 is displayed, due to a microswitch PCB failure.
Cause
Rotational failure of drum ITB motor
Items to Check
1) In service mode level 1 COPIER > FUNCTION > PART-CHK > MTR, enter 1 and press the OK key.
2) In service mode level 1 COPIER > FUNCTION > PART-CHK > MTR-ON, press the OK key to check
whether the motor is working normally.
3) Check whether 24V is supplied to J93 on the ITB drum motor. If yes, the ITB motor likely faulty.
4) If 24V is not supplied to the ITB drum motor, check whether 24V is output from fuse PCB J70-3 to the ITB
drum motor.
Also, check whether 24V is output from the fuse PCB J71-1 to the double switch PCB (microswitch PCB) and
also whether 24V is supplied to the fuse PCB J71-2 from the double switch PCB.
5) If there is no problem between the fuse PCB J71-1, -2 and the double switch PCB, the fuse PCB is likely
faulty.
If 24V is output from the fuse PCB J71-1 to the double switch PCB and not supplied to the fuse PCB J71-2,
check the double switch PCB.
