Description: Waste toner box is not installed into the machine.
Causes: 1 Rotation defective of release shaft A of waste toner box. 2 Harness connection failure between belt cleaner release sensor PCB and belt cleaner release solenoid. 3 Belt cleaner release sensor actuator performance defective. 4 Belt cleaner release sensor PCB failure. 5 Belt cleaner release solenoid failure. 6 Engine PCB failure.
Remedy: 1 Rotation defective of release shaft A of waste toner box. Replace the waste toner box. 2 Harness connection failure between belt cleaner release sensor PCB and belt cleaner release solenoid. Check the harness connection between the belt cleaner release sensor PCB and belt cleaner release solenoid and reconnect them. 3 Belt cleaner release sensor actuator performance defective Replace the belt cleaner release ASSY. 4 Belt cleaner release sensor PCB failure Check the sensor performance following the procedure described in “Maintenance mode 32”. If any problem occurs, replace the belt cleaner release sensor PCB ASSY. 5 Belt cleaner release solenoid failure Replace the belt cleaner release ASSY. 6 Engine PCB failure Replace the engine PCB ASSY
Remedy: 1 Waste toner sensor failure Check the sensor performance following the procedure described in “Maintenance mode 32”. If any problem occurs, replace the waste toner near/full sensor ASSY. 2 Harness connection failure of waste toner near/full sensor ASSY Check the harness connection of the waste toner near/full sensor ASSY and reconnect it. 3 Engine PCB failure Replace the engine PCB ASSY.
