Code :

Code: H4-30
Description: Non-contact main thermistor differential input abnormality (RTH1-d). The differential value does not rise above the specified level within the specified time from turning ON the HL1.
Causes: Thermistor trouble, heater lamp trouble, PCU PWB trouble, thermostat trouble, AC power trouble. Interlock switch trouble.
Remedy: Use Sim. 5-2 to check the flashing operation of the heater lamp. If the heater lamp flashes normally, check the thermistor and the harness. Check the thermistor input circuit section of the PCU PWB. If the heater lamp does not light up, check for disconnection of the heater lamp or the thermostat. Check the interlock switch. Check the lamp control circuit of the AC PWB and the PCU PWB. Use Sim. 14 to cancel the trouble.

Code: H5-01
Description: POIND not-reached jam is detected 5 times continuously
Causes: A fusing jam is not canceled completely. (Jam paper remains.) POD1 sensor trouble or harness connection trouble. Fusing unit instillation trouble.
Remedy: Check the fusing section jam paper. (winding, etc.) Check the POD1 sensor harness. Check installation of the fusing unit. Cancel the trouble with Sim. 14.

Code: H7-10
Description: Low temperature detection in the reset operation of temperature adjustment after alarm stop in a job (Noncontactmain thermistor(RTH1-d)). When in fusing alarm stopping, the specified temperature is not reached within the specified time. * Alarm stop: When the fusing temperature lowers than the specified level in a print job, the job is interrupted temporarily and temperature reset is performed.
Causes: Thermistor trouble, thermostat trouble, heater lamp trouble, PCU PWB trouble, AC power trouble, interlock switch trouble, connector and harness connection trouble.
Remedy: Use Sim. 5-2 to check the ON operation of the heater lamp. Check conduction of the thermostat. Replace the heater lamp, the PCU PWB, and the AC PWB. Check connection of the connector and the harness.

Code: H7-11
Description: Low temperature detection in the reset operation of temperature adjustment after alarm stop in a job (Sub thermistor (RTH2)). When in fusing alarm stopping, the specified temperature is not reached within the specified time. * Alarm stop: When the fusing temperature lowers than the specified level in a print job, the job is interrupted temporarily and temperature reset is performed.
Causes: Thermistor trouble, thermostat trouble, heater lamp trouble, PCU PWB trouble, AC power trouble, interlock switch trouble, connector and harness connection trouble.
Remedy: Use Sim. 5-2 to check the ON operation of the heater lamp. Check conduction of the thermostat. Replace the heater lamp, the PCU PWB, and the AC PWB. Check connection of the connector and the harness.

Code: H7-12
Description: Low temperature detection in the reset operation of temperature adjustment after alarm stop in a job (Lower thermistor (RTH2)). When in fusing alarm stopping, the specified temperature is not reached within the specified time. * When in fusing alarm stopping, the specified temperature is not reached within the specified time.
Causes: Thermistor trouble, thermostat trouble, heater lamp trouble, PCU PWB trouble, AC power trouble, interlock switch trouble, connector and harness connection trouble.
Remedy: Use Sim. 5-2 to check the ON operation of the heater lamp. Check conduction of the thermostat. Replace the heater lamp, the PCU PWB, and the AC PWB. Check connection of the connector and the harness.

Code: L1-00
Description: Mirror feed trouble. Mirror feed is not completed within the specified time
Causes: Mirror unit trouble. The mirror wire is disengaged. Circuit trouble.
Remedy: Use Sim. 1-1 to check the operation of the mirror. Check the mirror motor related circuits (SCN-Mother PWB, SCNCNT PWB, MHP sensor PWB).

Code: L2-10
Description: CCD cooling fan motor trouble (SCU detection). The lock signal is detected during rotation of the fan / The non-lock state is detected when the motor is not rotated in booting
Causes: Fan motor trouble, fan motor related harness and circuit trouble.
Remedy: Check the fan motor related circuits (SCN-Mother PWB, SCNCNT PWB) and their harness and connector.

Code: L2-11
Description: Lamp cooling fan motor trouble (SCU detection). The lock signal is detected during rotation of the fan / The non-lock state is detected when the motor is not rotated in booting
Causes: Fan motor trouble, fan motor related harness and circuit trouble.
Remedy: Check the fan motor related circuits (SCN-Mother PWB, SCNCNT PWB) and their harness and connector.
