E020-01C8-05 Error in take-up of Sealing Member (Y)
Detection Description The patch output value (SigR) failed to be 900 or less during initialization of the Developing Unit
(Y).
Remedy
[Related parts]
- Developing Unit (Y)
- Drum Unit (Y)
- DC Controller PCB
- Secondary Transfer High-Voltage PCB
- Primary Transfer High-Voltage PCB
- Power Supply Unit
- Laser Scanner Unit
- Main Controller PCB

- Registration Patch Sensor Unit
[Remedy] Perform the following in the order while checking whether the error is cleared.
a). If condensation in the Drum Unit is suspected, leave the Drum Unit as it is until the condensation
is cleared and then replace the Developing Unit.
b). If condensation is not possibly formed in the Drum Unit, perform the following in the order while
checking whether the error is cleared.
1. Check the disconnection of the Developing Unit Harness/Connector.
2. Check if the Developing Unit is properly installed.
3. Check if the Secondary Transfer High-Voltage PCB is properly installed (engagement of the
Fixing Claw, lifting of the PCB).
4. Check the disconnection of the DC Controller PCB Harness/Connector.
5. Check the disconnection of the Main Controller PCB Harness/Connector.
6. Check the disconnection of the Power Supply Unit Harness/Connector.
7. Check the disconnection of the Laser Scanner Unit Harness/Connector.
8. Check the disconnection of the Primary Transfer High-Voltage PCB Harness/Connector.
9. Check the disconnection of the Registration Patch Sensor Unit Harness/Connector.
10. Replace the Developing Unit.
11. Replace the Drum Unit.
12. Replace the DC Controller PCB.
13. Replace the Secondary Transfer High-Voltage PCB.
14. Replace the Power Supply Unit.
15. Replace the Laser Scanner Unit.
16. Replace the Main Controller PCB.
17. Replace the Primary Transfer High-Voltage PCB.
18. Replace the Intermediate Transfer Belt Assembly.
19. Replace the Registration Patch Sensor Unit.
20. Replace the Main Drive Unit.
[Reference] Before replacing the DC Controller PCB, back up the service mode data and restore
the backup data after the replacement so the data may be able to be protected.
- Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP
- Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
[Reference] Before replacing the Main Controller PCB, back up the service mode data 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
