Causes: The Main Controller PCB did not detect 24 V when the main power was turned ON.
Remedy: [Related parts] R1.00 - Harness between the Main Controller PCB (UN81/J4509) and the Low-voltage Power Supply PCB (UN01/J313) - Low-voltage Power Supply PCB (UN01) - Main Controller PCB (UN81) [Remedy] Check/replace the related harness/cable, connector and parts. [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
