• Code: E733-0000
• Description: Printer communication error
  Communication between the DC Controller PCB and the Main Controller PCB was not available at startup.
• Remedy: [Related parts] - DC Controller PCB (UN04/J20) and the Harness between the Low-voltage Power Supply PCB (UN01/J315) (Unit of replacement: CABLE, POWER SUPPLY) - Flexible Cable between the DC Controller PCB (UN04/ J112) and the Main Controller PCB (UN81/J7001) (Unit of replacement: CABLE, FLAT) - DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY) - Main Controller PCB (UN81) (Unit of replacement: MAIN CONTROLLER PCB ASSEMBLY) [Points to note at work] When checking the harness/cable or connector, perform the following work. 1. Disconnect and then connect the connector to check that there is no bent pin and cable disconnection. 2. Visually check that the harness is not caught or open circuit. 3. If there is any error, replace the corresponding harness/cable. [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 Low-voltage Power Supply PCB. 2. Check the harness between the DC Controller PCB and the Main Controller PCB. 3. Turn ON the power, and check if the initialization is executed at startup. 3-1. If the initialization is not executed, replace the DC Controller PCB. 3-2. 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
