Power supply (24 V) error
The ADF Driver PCB did not detect 24 V after the start of a job.
[Related parts]
- Harnesses from the Main Controller PCB to the ADF Driver PCB
1. Main Controller PCB (UN05/J38) to Relay Connector (2P) (Unit of replacement: CABLE, ADF
POWER CONNECTING)
2. Relay Connector (2P) to ADF Driver PCB (PCB1/J1411)
- Harness between the Main Controller PCB (UN05/J20) and the Low Voltage Power Supply PCB
(UN01/J313) (Unit of replacement: POWER SUPPLY ASSEMBLY)
- ADF Driver PCB (PCB1)
- Main Controller PCB (UN05) (Unit of replacement: MAIN 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.
- When an error is detected, conduction of 24 V is stopped. At power check, check if 24 V is
conducted by repeating power cycling of the machine.
1. Measure the Low Voltage Power Supply PCB (J313/pin 3) using a tester.
2. When 24 V is not output to the Low Voltage Power Supply PCB (J313/pin 3), replace the Low
Voltage Power Supply PCB.
3. When 24 V is output to the Low Voltage Power Supply PCB (J313/pin 3), measure the Main
Controller PCB (J20/pin 3) using a tester.
4. When 24 V is not output to the Main Controller PCB (J20/pin 3), check the harness between the
Main Controller PCB and the Low Voltage Power Supply PCB.
5. When 24 V is output to the Main Controller PCB (J20/pin 3), measure the Main Controller PCB
(J38/pin 2) using a tester.
6. When 24 V is not output to the Main Controller PCB (J38/pin 2), replace the Main Controller
PCB.
7. When 24 V is output to the Main Controller PCB (J38/pin 2), measure the ADF Driver PCB
(J1411/pin 2) using a tester.
8. When 24 V is not output to the ADF Driver PCB (J1411/pin 2), check the harnesses from the
Main Controller PCB to the ADF Driver PCB.
9. When 24 V is output to the ADF Driver PCB (J1411/pin 2), replace the ADF Driver PCB.
Controller communication error
A sequence error with the controller occurred.
[Related parts]
- Flexible Cable between the DC Controller PCB (UN04/J110) and the Main Controller PCB (UN05/
J18) (Unit of replacement: CABLE, FLAT)
- DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY)
- Main Controller PCB (UN05) (Unit of replacement: MAIN CONTROLLER PCB 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] Perform the following in the order while checking whether the error is cleared.
1. Check the harness between the DC Controller PCB and the Main Controller PCB.
2. Turn ON the power, and check if the initialization is executed at startup.
2-1. If the initialization is not executed, replace the DC Controller PCB.
2-2. If the initialization is executed, replace the Main Controller 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.
