Serial communication error
A communication error of ASIC in the DC Controller PCB was detected.
[Remedy] Replace the DC Controller PCB (UN04). (Unit of replacement: DC CONTROLLER PCB
ASSEMBLY)
[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
Serial communication error
A communication error between the DC Controller PCB and the Cassette Unit PCB was detected.
[Related parts]
- Harness between the DC Controller PCB (UN04/J126) and the Cassette Unit PCB (Unit of
replacement: CABLE, FEED MOTOR)
- Cassette Unit PCB (Unit of replacement: CASSETTE ASSEMBLY)
- DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY)
[Remedy] Check/replace the related harness/cable, connector and parts.
