Code :

Code: L4-60
Description: Fusing pressure roller cooling fan motor F trouble. When the fan is operated, the fan operation signal is not detected within the specified time.
Causes: Harness connection trouble between the PCU PWB and the fan motor. PCU PWB trouble. Fan motor trouble. The fan does not rotate because of the other trouble. (No power supply to the fan motor)
Remedy: Use SIM6-2 to check the operation of the fan motor. Check the harness and the connector between the PCU PWB and the fan motor. Replace the PCU PWB. Replace the fan motor.

Code: L4-61
Description: Fusing pressure roller cooling fan motor R trouble. When the fan is operated, the fan operation signal is not detected within the specified time.
Causes: Harness connection trouble between the PCU PWB and the fan motor. PCU PWB trouble. Fan motor trouble. The fan does not rotate because of the other trouble. (No power supply to the fan motor)
Remedy: Use SIM6-2 to check the operation of the fan motor. Check the harness and the connector between the PCU PWB and the fan motor. Replace the PCU PWB. Replace the fan motor.

Code: L6-10
Description: Polygon motor trouble. The polygon motor does not reach the specified RPM within the specified time after starting rotation of the polygon motor.
Causes: Polygon motor trouble. LSU control PWB trouble. Connection trouble of the connector and the harness.
Remedy: Use SIM61-1 to check the operation of the polygon motor. Check connection of the connector and the harness. Replace the LSU. Replace the LSU control PWB.

Code: L8-01
