• Code: C0072
• Description: Main Hopper Toner Replenishing Motor’s failure to turn
  • The Toner Bottle Home Position Sensor does not go HIGH within 5 sec. after the motor has started turning. • The Toner Bottle Home Position Sensor does not go LOW within 10 sec. after the motor has started turning and the sensor has gone HIGH. • The motor is stationary or the Toner Bottle Home Position Sensor is HIGH 2 sec. after the motor has stopped turning.
• Remedy: 1 Toner Bottle turns when the Toner Bottle is turned a half turn and the Front Door is closed. NO Correct drive coupling. 2 I/O check for Toner Bottle Home Position Sensor operation: the voltage across PJ11A-5 on Master Board and GND is DC5V (Toner Bottle at home position) and DC0V (Toner Bottle at a position other than home) when step 1 is performed. YES Change Master Board. NO Check sensor for installation. Correct detecting plate. Change sensor. 3 Main Hopper Toner Replenishing Motor rotation: the voltage across PJ11A-1 on Master Board and GND is DC0V (Toner Bottle at a stop) and DC24V (Toner Bottle turning) when step 1 is performed. YES Change motor. NO Change Master Board.

• Code: C0090
• Description: Developing Unit Drive Motor’s failure to turn
  • The Lock signal remains HIGH for a continuous period of 1.5 sec. or more after the lapse of 10 sec. after the motor has started turning. • The Lock signal remains LOW for a continuous period of 1.5 sec. or more after the lapse of 10 sec. after the motor has stopped turning.
• Remedy: 1 Developing Unit Drive Motor rotation: the voltage across PJ7A-7A on Master Board and GND is DC5V (motor deenergized) and DC0V (motor energized) when the Start key is pressed. NO Change Master Board. 2 Developing Unit Drive Motor rotation: the voltage across PJ7A-6A on Master Board and GND is DC5V (motor deenergized) and DC0V (motor energized) when the Start key is pressed. YES Correct drive coupling. Correct installed position of the Developing Unit. Change motor. NO Change Master Board.

• Code: C0210
• Description: Image Transfer/Paper Separator Corona charge leak detected
  The Charge Leak Detection signal (SCD) remains ON for a continuous period of 0.3 sec. after the Image Transfer/Paper Separator Corona output has been turned ON.
• Remedy: 1 The Image Transfer/Paper Separator Coronas Unit is installed properly. NO Correct installed position. 2 The Image Transfer/Paper Separator Coronas wires are dirty or have snapped. YES Clean or change. 3 The malfunction code appears even with PJ2HV1 unplugged. YES Change Master Board. NO Change the HV.

• Code: C0400
