Patch Sensor error
The Patch Sensor detected light intensity error of the LED for B&W printing at initialization of the
Developing Assembly.
[Related parts] R1.00
- Harness between the DC Controller PCB (UN1/J125) and the Patch Sensor (UN49/J1253)
- Harness between the Front Driver PCB (UN3/J305) and the Registration Shutter Solenoid (SL1/
J6064)
- Patch Sensor (UN49)
- Registration Shutter Solenoid (SL1)
- DC Controller PCB (UN1)
[Remedy] Perform the following in the order while checking whether the error is cleared.
1. Remove soiling on the Patch Sensor.
2. Check the operation of the Registration Shutter Solenoid.
3. 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.
