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. Remove and then install the Drum Unit (Y), and check whether the error is cleared. [Reference] EEPROMs on the Drum Units of all colors are connected each other with signal cables. Therefore, even if the error is not cleared with step 1, it may be cleared by removing and then installing the Drum Units of all colors. 2. Check that the Front Cover/Right Cover is closed. 3. Visually check that the Interlock Switch 1 and 2 are turned ON/OFF by opening/closing the Front Cover/Right Cover. 4. Turn OFF and then ON the main power, and check whether the error is cleared. 5. Check that the harness between the Interlock Switch 1 and 2 and the DC Controller PCB is not short-circuited (the harness does not come in contact with the plate while the cable sheath is peeled). 6. Check if the Drum Unit Memory PCB (Y) and the Drum Unit Relay PCB (Y) are damaged or deformed, and replace the Drum Unit (Y) if necessary. 7. Check if the Drum Unit Memory PCB (Y) and the Drum Unit Relay PCB (Y) are soiled. If it is soiled, clean it with a blower. 8. Disconnect the connector (J24) of the DC Controller while the Front Cover and the Right Cover are closed, and measure the resistance value between the connectors J24/1-pin and the J24/2-pin on the J24 harness side using a tester. a. If the measurement value is less than 1 ohm (conduction state), 1. Replace the DC Controller PCB. 2. Replace the Low-voltage Power Supply PCB. b. If the measurement value is 1 ohm or higher (non conduction state), replace the harness between the Interlock Switch 1 and 2 and the DC Controller PCB. 9. Check the harness between the Low-voltage Power Supply PCB and the DC Controller PCB. 10. Replace the DC Controller PCB. 11. Replace the Low-voltage Power Supply PCB.
