Remedy [Related parts]
- Main Drive Unit (Unit of replacement: MAIN DRIVE
ASSEMBLY)
- Harnesses connecting the Bk Drum_ITB Motor (M02/J5702),
the Relay Connector (8P) and the DC Controller PCB (UN04/
J140) (Unit of replacement: MAIN DRIVE ASSEMBLY)
- Fuse in the Low-voltage Power Supply PCB (UN01/FU14) (Unit
of replacement: POWER SUPPLY ASSEMBLY)
- Bk Drum_ITB Motor (M02) (Unit of replacement: MOTOR, DC)
- DC Controller PCB (UN04) (Unit of replacement: DC
CONTROLLER PCB ASSEMBLY)
- Low-voltage Power Supply PCB (UN01) (Unit of replacement:
POWER SUPPLY ASSEMBLY)
[Points to note at work] When checking the harness/cable or
connector, perform the following work.
1. Disconnect and then connect the connector to check that
there is no bent pin and cable disconnection.
2. Visually check that the harness is not caught or open circuit.
3. If there is any error, replace the corresponding harness/cable.
[Remedy] It is highly possible that the Bk Drum_ITB Motor is
not rotating due to overload or an electrical trouble. Perform
the following in the order while checking whether the error is
cleared.
1. Check whether the gears of the Main Drive Unit can be
rotated by hand.
a. If they cannot be rotated, replace the Main Drive Unit.
b. If they can be rotated, check the harnesses from the Bk
Drum_ITB Motor to the DC Controller PCB.
2. Measure the both ends of the fuse in the Low-voltage Power
Supply PCB using a tester.
a. If power is flowing to it (the measurement value is less than
1 ohm),
1. Replace the Bk Drum_ITB Motor.
2. Replace the DC Controller PCB.
b. If the power is not flowing to it (the measurement value is 1
ohm or higher), replace the Low-voltage Power Supply PCB.
[Reference] Before replacing the DC Controller PCB, back up
the service mode data (approx. 2 min) and restore the backup
data after the replacement so the data may be able to be
protected.
