• Code: 733-0010-00
• Description: Printer communication error
• Causes: A communication error between the DC Controller PCB and the Main Controller PCB was detected.
• Remedy: [Related parts] - Harness between the Main Controller PCB 2 (PPWB2/J5201) and the DC Controller PCB (UN01/ J443) (Unit of replacement: CABLE, COMMUNICATION) - Harness between the Main Controller PCB 2 (PPWB2/J5202) and the DC Controller PCB (UN01/ J442) (Unit of replacement: CABLE, SIGNAL) - DC Controller PCB (UN01) (Unit of replacement: DC CONTROLLER PCB ASS'Y) - Main Controller PCB 2 (PWB02) (Unit of replacement: MAIN CONTROLLER PCB ASS'Y, 2) - Main Controller PCB 1 (PWB01) (Unit of replacement: MAIN CONTROLLER PCB ASS'Y, 1) [Remedy] Perform the following in the order while checking whether the error is cleared. 1. Reinstall the latest system software using SST or a USB memory. 2. 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

• Code: 733-0F00-05
• Description: Printer communication error
• Causes: Communication error that can be recovered by reboot If it is detected again immediately after reboot, E733-0000 is generated.
• Remedy: It is not necessary to perform a remedy because the machine is automatically rebooted after log collection.
