Code: E733 0002
Description: Printer communication error. DDI-P communication error (invalid packet) was detected.
Remedy: [Related parts] • Harness between the DC Controller PCB (UN04/J110) and the Main Controller PCB (UN05/J18) (Unit of replacement: DDIP, CABLE) • DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY) • Main Controller PCB (UN05) (Unit of replacement: MAIN CONTROLLER PCB ASSEMBLY) [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

Code: E733 0F01
Description: Printer communication error. Communication error that can be recovered by reboot If it is detected again immediately after reboot, E733-0001 is generated.
Remedy: It is not necessary to perform a remedy because the machine is automatically rebooted after log collection

Code: E733 0F02
Description: Printer communication error. Communication error that can be recovered by reboot If it is detected again immediately after reboot, E733-0002 is generated.
Remedy: It is not necessary to perform a remedy because the machine is automatically rebooted after log collection.

Code: E733 F001
Description: Printer communication error. Disconnection of a cable between the Main Controller PCB and the DC Controller PCB was detected.
Remedy: Check/replace the harness between the DC Controller PCB (UN04/J110) and the Main Controller PCB (UN05/J18). (Unit of replacement: DDIP, CABLE)

Code: E733 F002
Description: Printer communication error. Disconnection of a cable between the Main Controller PCB and the Y/M Laser Driver PCB was detected.
Remedy: [Related parts] • Flat Cable between the Main Controller PCB (UN05/J19) and the Y/M Laser Driver PCB (UN08/J201) (Unit of replacement: FLEXIBLE FLAT CABLE ASSEMBLY) • Flat Cable between the Y/M Laser Driver PC (UN08/J203) and the C/Bk Laser Driver PCB (UN09/J801) (Unit of replacement: CABLE, FLAT) [Remedy] Check/replace the related harness/cable, connector and parts.

Code: E744 0001
Description: Language file error. The language file in the Flash PCB was not supported by the version of Bootable.
Remedy: Reinstall the correct language file or system software using SST or a USB memory

Code: E744 4000
Description: Error due to the DC Controller PCB not compatible with the model. The DC Controller PCB which was used with another model 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
