Controller communication error
An error in receiving data from the controller was detected.
[Related parts] R1.00
- Harness between the DC Controller PCB (UN04/J112) and the Main Controller PCB (UN81/
J4511)
- DC Controller PCB (UN04)
- Main Controller PCB (UN81)
[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.
- Backup: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMBUP
- Restoration: COPIER (LEVEL2)> FUNCTION> SYSTEM> DSRAMRES
Controller communication error
A sequence error with the controller occurred.
