• Code: H3-02
• Description: Fusing section high temperature trouble (HL3)
  The fusing temperature exceeds 241.5 °C. (An input voltage of 1.3V or less is detected.) When fusing temperature control is started and a temperature of 242 °C is detected 3 times continuously in sampling of 250 msec interval. (In the interval of 150ms)
• Causes: Thermistor trouble Control PWB trouble Improper connection of the fusing section connector AC power trouble
• Remedy: Use SIM 5-2 to check flashing of the heater lamp. When the lamp flashes normally. • Check the thermistor and the harness. • Check the thermistor input circuit on the control PWB. When the lamp keeps ON. • Check the AC PWB and the lamp control circuit on the control PWB. Use SIM 14 to cancel the trouble

• Code: H4-00
• Description: Fusing section low temperature trouble (HL1)

• Code: H5-01
• Description: 5-times continuous POD notreached JAM detection
  When POD1 not-reached jam is detected 5-times continuously. POD1 jam counter is backed up and used in a print job after turning on the power. The counter is cleared when POD1 jam does not occur in a job or when the trouble is canceled.
• Causes: The fusing jam is not canceled completely. (Jam paper remains.)
  POD1 sensor trouble, or harness connection trouble
  Fusing unit installation trouble
• Remedy: Case 1 Cause The fusing jam is not canceled completely. (Jam paper remains.) Check and remedy Check for jam paper in the fusing section. (Winding, etc.) Case 2 Cause POD1 sensor trouble, or harness connection trouble Check and remedy Check the PODC1 sensor harness and installation of the fusing unit. Case 3 Cause Fusing unit installation trouble Check and remedy Use SIM 14 to cancel the trouble
