• Code: E012-0001-05
• Description: CL Drum Motor error
• Causes: It did not become the specified speed for 500 consecutive msec although 1000 msec have passed 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] R1.00 - Harness between the CL Drum Motor (M01/J5701) and the DC Controller PCB (UN04/J140) - Fuse in the Low-voltage Power Supply PCB (UN01/FU14) - CL Drum Motor (M01) - Main Drive Unit - Low-voltage Power Supply PCB (UN01) - DC Controller PCB (UN04) [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 power is flowing to it (the measurement value is less than 1 ohm), 1. Replace the CL Drum Motor. 2. Replace the DC Controller PCB. b. If the power is not flowing to it (the measurement value is 1 ohm or higher), replace the Lowvoltage 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
