• Code: 0300
• Description: Polygon motor rotation trouble
  • The polygon motor (M9) fails to turn stably even after the lapse of a given period of time after activating the polygon motor. • Motor lock signal detects HIGH for a given period time consecutively during the polygon motor (M9) is rotating.
• Remedy: 1 Check the connector between PH unit-PRCB CN19, CN20 for proper connection and correct as necessary. 2 Change PH unit 3 Change PRCB

• Code: 0310
• Description: Laser malfunction
  • SOS signal is not detected even after the lapse of a given period of time after starting the laser output. • SOS signal is not detected for a given period of time during printing.
• Remedy: 1 Check the connector between PH unit-PRCB CN19, CN20 for proper connection and correct as necessary. 2 Change PH unit 3 Change PRCB

• Code: 0500
• Description: Fusing heaters trouble (center)
  • Detected temperature of the heating roller thermistor (TH2; center) does not go up a given range of temperature even after a lapse of given period of time at warm up. • The warm-up is not completed even after the set period of time has elapsed after the warm-up is started.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the right door. 3 Check the fusing unit CN30-PRCB CN16, fusing unit-relay CN4AC-DCPU CN2 for proper connection and correct or change as necessary. 4 Change fusing unit 5 Change PRCB 6 Change DCPU

• Code: 0501
• Description: Fusing heaters trouble (edge)
  • Detected temperature of the heating roller thermistor (TH2; edge) does not go up a given range of temperature even after a lapse of given period of time at warm up. • The warm-up is not completed even after the set period of time has elapsed after the warm-up is started.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the right door. 3 Check the fusing unit CN30-PRCB CN16, fusing unit-relay CN4AC-DCPU CN2 for proper connection and correct or change as necessary. 4 Change fusing unit 5 Change PRCB 6 Change DCPU

• Code: 0510
• Description: Fusing abnormally low temperature detection (center)
  Detected temperature of the heating roller thermistor (TH2; center) goes below a given temperature for a given period of time consecutively after warm up is completed.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the right door. 3 Check the fusing unit CN30-PRCB CN16, fusing unit-relay CN4AC-DCPU CN2 for proper connection and correct or change as necessary. 4 Change fusing unit 5 Change PRCB 6 Change DCPU

• Code: 0511
• Description: Fusing abnormally low temperature detection (edge)
  Detected temperature of the heating roller thermistor (TH2; edge) goes below a given temperature for a given period of time consecutively after warm up is completed.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the right door. 3 Check the fusing unit CN30-PRCB CN16, fusing unit-relay CN4AC-DCPU CN2 for proper connection and correct or change as necessary. 4 Change fusing unit 5 Change PRCB 6 Change DCPU

• Code: 0520
• Description: Fusing abnormally high temperature detection (center)
  Detected temperature of the heating roller thermistor (TH2; center) goes beyond a given temperature for a given period of time consecutively.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the right door. 3 Check the fusing unit CN30-PRCB CN16, fusing unit-relay CN4AC-DCPU CN2 for proper connection and correct or change as necessary. 4 Change fusing unit 5 Change PRCB 6 Change DCPU

• Code: 0521
• Description: Fusing abnormally high temperature detection (edge)
  Detected temperature of the heating roller thermistor (TH2; edge) goes beyond a given temperature for a given period of time consecutively.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the right door. 3 Check the fusing unit CN30-PRCB CN16, fusing unit-relay CN4AC-DCPU CN2 for proper connection and correct or change as necessary. 4 Change fusing unit 5 Change PRCB 6 Change DCPU
