DADF Scanner Unit HP error
The DADF Scanner Unit could not detect the home position when completing scanning operation.
[Related parts] R1.01
- Harness between the ADF Driver PCB (UN_BO1/J408) and the Glass Movement HP Sensor
(PS_A9/J462)
- Glass Movement HP Sensor (PS_A9)
- Glass Movement Gear 18T
- ADF Driver PCB (UN_BO1)
[Remedy] Check/replace the related harness/cable, connector and parts.
Power supply error
The Reader Controller PCB did not detect 24 V when the main power was turned ON.
[Related parts] R1.00
- Harness between the Reader Controller PCB (UN_BO1/J104) and the DADF Driver PCB (PCB1/
J402)
- Harness between the Reader Controller PCB (UN_BO1/J4) and the Relay PCB (UN5/J407)
- Harness between the Relay PCB (UN5/J405) and the 24V Power Supply PCB (UN10/J834)
- Reader Controller PCB (UN_BO1)
- DADF Driver PCB (PCB1)
- Relay PCB (UN5)
- 24V Power Supply PCB (UN10)
[Remedy] Check/replace the related harness/cable, connector and parts.
[Reference]
- When an error is detected, conduction of 24 V is stopped. At power check, check if 24 V is
conducted or rated voltage is output by repeating power cycling of the machine.
- Before replacing the Reader 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.
Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> RSRAMBUP
Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> RSRAMRES
