Code: 30
Description: Incorrect EL lamp current value
Causes: 1 Drum unit electrode dirty.
Remedy: Clean the electrodes on the drum unit.
Code: 31
Description: Density sensor failure
Causes: 1 Harness connection failure of density sensor holder ASSY. 2 Harness connection failure of density sensor solenoid ASSY. 3 Density sensor holder ASSY failure. 4 Transfer HVPS PCB unit failure. 5 Engine PCB failure.
Remedy: 1 Harness connection failure of density sensor holder ASSY Check the harness connection between the density sensor holder ASSY and registration relay PCB, and the one between the registration relay PCB and engine PCB. Then, reconnect them. 2 Harness connection failure of density sensor solenoid ASSY Check the harness connection between the engine PCB and registration relay PCB and reconnect them. 3 Density sensor holder ASSY failure Replace the density sensor holder ASSY. 4 Transfer HVPS PCB unit failure Replace the transfer HVPS PCB unit. 5 Engine PCB failure Replace the engine PCB ASSY.
Code: 32
