• Code: C0094
• Description: 2nd Image Transfer Roller pressure/retraction failure
  • The 2nd Image Transfer Pressure Position Sensor is not activated (retracted position) within 1 sec. after the 2nd Image Transfer Roller has started its retracting motion. • The 2nd Image Transfer Pressure Position Sensor is not deactivated (not the retracted position) within 1 sec. after the 2nd Image Transfer Roller has started its pressing motion.
• Remedy: 1 While the 2nd Image Transfer Pressure/ Retraction Clutch is supposed to be deenergized during timing of pressure/retraction operation: the voltage across PJ14I-9A on Master Board and GND is DC 24 V when the clutch is deenergized and DC 0 V when the clutch is energized. YES: Check connector for connection. Check for overload. Change clutch. NO: Change Master Board. 2 I/O check for 2nd Image Transfer Pressure Position Sensor operation during pressure/ retraction operation: the voltage across PJ14I-6B on Master Board and GND is DC 0 V when the sensor is unblocked and DC 5 V when the sensor is blocked (pressed position). YES: Change Master Board. NO: Correct actuator. Check sensor connector for connection. Change sensor.

Change motor. Change Master Board. 2 I/O check for 1st Image Transfer Retraction Position Sensor operation during pressure/ retraction operation: the voltage across PJ17I-1A on Master Board and GND is DC 0 V when the sensor is unblocked and DC 5 V when the sensor is blocked (retracted position). YES: Change Master Board. NO: Correct actuator. Check sensor connector for connection. Change sensor.

• Code: C0098
• Description: Fusing Roller pressure/ retraction failure
  • No change is observed in the encoder pulse even after the lapse of 0.5 sec. after the Fusing Pressure/Retraction Motor has started turning for retraction direction during retraction control. • No change is observed in the encoder pulse even after the lapse of 0.5 sec. after the Fusing Pressure/Retraction Motor has started turning for pressure direction during pressure control. • The Fusing Pressure Position Sensor is not activated (pressed position) even when 31 motor encoder pulses have been counted after the Fusing Pressure/Retraction Motor has started turning for pressure direction during pressure control.
• Remedy: 1 Fusing Pressure/Retraction Motor rotation when the Fusing Roller is retracted: the voltage across PJ14I-4A on Master Board and GND is DC 0 V when the motor is deenergized and DC 24 V when the motor is energized.

NO: Change Master Board. 2 I/O check for Fusing Pressure Position Sensor when the Fusing Roller is retracted: the voltage across PJ6I-11B on Master Board and GND is DC 0 V when the sensor is unblocked (retracted position) and DC 5 V when the sensor is blocked. YES: Change Master Board. NO: Check sensor installation. Correct detecting plate. Check sensor connector for connection. Change sensor. 3 Fusing Pressure/Retraction Motor rotation when the Fusing Roller is pressed: the voltage across PJ14I-5A on Master Board and GND is DC 0 V when the motor is deenergized and DC 24 V when the motor is energized. NO: Change Master Board. 4 I/O check for Fusing Pressure Position Sensor when the Fusing Roller is pressed: the voltage across PJ6I-11B on Master Board and GND is DC 0 V when the sensor is unblocked and DC 5 V when the sensor is blocked (pressed position). YES: Change Master Board. NO: Check sensor installation. Correct detecting plate. Check sensor connector for connection. Change sensor. 5 I/O check for Fusing Retraction Position Sensor operation while the Fusing Pressure/ Retraction Motor is turning: the voltage across PJ17I-3B on Master Board and GND remains DC 0 V when the sensor is unblocked or remains DC 5 V when the sensor is blocked while the motor remains stationary, and alternates between DC 0 V when the sensor is unblocked and DC 5 V when the sensor is blocked while the motor is turning. YES: Change Master Board. NO: Check sensor installation. Correct detecting plate. Check sensor connector for connection. Change sensor.
