• Description: CL Drum Motor error. The specified speed could not be maintained for 0.5 consecutive sec although it became the specified speed at least once from the startup of the CL Drum Motor in the Main Drive Unit. (The detection timing varies depending on the paper feed conditions.)
• Remedy: [Related parts] • Harness between the CL Drum Motor (M03/J1103) and the DC Controller PCB (UN04/J129) (Unit of replacement: CABLE, MAIN DRIVE) • Main Drive Unit (Unit of replacement: MAIN DRIVE ASSEMBLY) • CL Drum Motor (M03) • DC Controller PCB (UN04) (Unit of replacement: DC CONTROLLER PCB ASSEMBLY) • Low Voltage Power Supply PCB (UN01) (Unit of replacement: POWER SUPPLY ASSEMBLY) [Remedy] Perform the following in the order while checking whether the error is cleared. 1. Check whether the gears of the Main Drive Unit can be rotated by hand. a. If they cannot be rotated, replace the Main Drive Unit. b. If they can be rotated, check the harness between the CL Drum Motor and the DC Controller PCB. 2. Measure the both ends of the fuse in the Low Voltage Power Supply PCB using a tester. a. If the measurement value is less than 1 ohm (conduction state), 1. Replace the CL Drum Motor. 2. Replace the DC Controller PCB. b. If the measurement value is 1 ohm or higher (non conduction state), replace the Low Voltage Power Supply 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
