Fixing disengagement timeout error
The Fixing Pressure Release Sensor did not detect OFF status within 10 sec after the start of fixing
disengagement operation.
[Related parts]
- Harnesses from the DC Controller PCB to the Fixing Pressure Release Sensor
1. DC Controller PCB (UN04/J122) to Relay Connector (11P) (Unit of replacement: CABLE, FEED)
2. Relay Connector (11P) to Fixing Pressure Release Sensor (PS13) (Unit of replacement: PAPER
DELIVERY DRIVE ASSEMBLY)
- Harnesses from the DC Controller PCB to the Fixing Motor
1. DC Controller PCB (UN04/J122) to Relay Connector (8P) (Unit of replacement: CABLE, FEED)
2. Relay Connector (8P) to Fixing Motor (M09) (Unit of replacement: FIXING DRIVE MOTOR
ASSEMBLY)
- Fixing Unit (Unit of replacement: FIXING ASSEMBLY)
- DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY)
- Fixing Pressure Release Sensor (PS13)
- Fixing Drive Unit (Unit of replacement: FIXING DRIVE ASSEMBLY)
[Remedy] Check/replace the related harness/cable, connector and parts.
[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.

Bk Drum_ITB Motor error
It did not become the specified speed for 0.5 consecutive sec although 0.8 sec have passed from
the startup of the Bk Drum_ITB Motor in the Main Drive Unit.
[Related parts]
- Harness between the Bk Drum_ITB Motor (M02/J1054) and the DC Controller PCB (UN04/J129)
(Unit of replacement: CABLE, MAIN DRIVE)
- Main Drive Unit (Unit of replacement: MAIN DRIVE ASSEMBLY)
- Bk Drum_ITB Motor (M02)
- DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY)
- Low Voltage Power Supply PCB (UN01) (Unit of replacement: POWER SUPPLY ASSEMBLY)
[Remedy] 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 harness between the Bk Drum_ITB Motor and the DC Controller
PCB.
2. Measure the both ends of the fuse in the Low Voltage Power Supply PCB using a tester.
a. If the measurement value is less than 1 ohm (conduction state),
1. Replace the Bk Drum_ITB Motor.
2. Replace the DC Controller PCB.
b. If the measurement value is 1 ohm or higher (non conduction state), 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.
