• Code: H2-00
• Description: Thermistor open
  The thermistor is open. The fusing unit is not installed.
• Causes: Thermistor abnormality.
  Control PWB abnormality.
  Fusing section connector disconnection.
  The fusing unit is not installed.
• Remedy: Check the harness and the connector between the thermistor and the PWB. Use SIM 14 to clear the self diagnostic display.

• Code: H3-00
• Description: Heat roller high temperature detection
  The fusing temperature exceeds 240C°.
• Causes: Thermistor abnormality.
  Control PWB abnormality.
  Fusing section connector disconnection.
• Remedy: Use SIM 5-02 to check the heater lamp blinking operation. When the lamp blinks normally. Check the thermistor and its harness. Check the thermistor input circuit on the control PWB. When the lamp keeps ON. Check the power PWB and the lamp control circuit on the MCU PWB. Use SIM 14 to clear the self diagnostic display.

• Code: H4-00
• Description: Heat roller low temperature detection
  When the fusing temperature is lower than 150C° after 55sec from the start of warming up.
  When the warming up complete temperature is not reached in 30sec from reaching 150C°.
  When the fusing temperature is lower than 100C° after 20sec from ready start.
  When the fusing temperature is lower than 145C° when printing.
• Causes: Thermistor abnormality.
  Heater lamp abnormality.
  Thermostat abnormality.
  Control PWB abnormality.
• Remedy: Use SIM 5-02 to check the heater lamp blinking operation. When the lamp blinks normally. Check the thermistor and its harness. Check the thermistor input circuit on the control PWB. When the lamp does not light up. Check for disconnection of the heater lamp and the thermostat. Check the interlock switch. Check the power PWB and the lamp control circuit on the MCU PWB. Use SIM 14 to clear the self diagnostic display.

• Code: H5-01
• Description: 5-time continuous detections of POUT not-reached jam
  Paper not-reached jams are detected 5 times or more continuously by the paper exit sensor (POUT). The jam counter is backed up and used for jobs after turning on the power.
• Causes: A fusing jam is not canceled completely. (A jam paper remains in the machine.)
  Paper exit sensor trouble or harness connection trouble
  Defective installation of the fusing unit.
• Remedy: Check the fusing section jam (for winding, etc.). Check the POUT sensor harness. Check installation of the fusing unit. Use SIM14 to clear the self diag display.
