• Code: 0303
• Description: Polygon Motor/Y failure to turn
  • The Polygon motor fails to turn stably even after the lapse of a given period of time after activating the Polygon motor. • Motor Lock signal detects H for a given period time consecutively during the Polygon motor is rotating.
• Remedy: 1 Check the connector for proper connection and correct as necessary. 2 Change PH Unit. 3 Change PWB-D. 4 Change PWB-M7.

• Code: 0304
• Description: Polygon Motor/K failure to turn
  • The Polygon motor fails to turn stably even after the lapse of a given period of time after activating the Polygon motor. • Motor Lock signal detects H for a given period time consecutively during the Polygon motor is rotating.
• Remedy: 1 Check the connector for proper connection and correct as necessary. 2 Change PH Unit. 3 Change PWB-D. 4 Change PWB-M7.

• Code: 0311
• Description: Laser malfunction (Cyan)
  • SOS signal is not detected even after the lapse of a given period of time after staring the laser output. • SOS signal is not detected for a given period of time during printing or IDC sensor adjustment.
• Remedy: 1 Check the connector for proper connection and correct as necessary. 2 Change PH Unit. 3 Change PWB-D. 4 Change PWB-M7.

• Code: 0312
• Description: Laser malfunction (Magenta)
  • SOS signal is not detected even after the lapse of a given period of time after staring the laser output. • SOS signal is not detected for a given period of time during printing or IDC sensor adjustment.
• Remedy: 1 Check the connector for proper connection and correct as necessary. 2 Change PH Unit. 3 Change PWB-D. 4 Change PWB-M7.

• Code: 0313
• Description: Laser malfunction (Yellow)
  • SOS signal is not detected even after the lapse of a given period of time after staring the laser output. • SOS signal is not detected for a given period of time during printing or IDC sensor adjustment.
• Remedy: 1 Check the connector for proper connection and correct as necessary. 2 Change PH Unit. 3 Change PWB-D. 4 Change PWB-M7.

• Code: 0314
• Description: Laser malfunction (Black)
  • SOS signal is not detected even after the lapse of a given period of time after staring the laser output. • SOS signal is not detected for a given period of time during printing or IDC sensor adjustment.
• Remedy: 1 Check the connector for proper connection and correct as necessary. 2 Change PH Unit. 3 Change PWB-D. 4 Change PWB-M7.

• Code: 0500
• Description: Heating Roller warm-up failure
  • The Heating Roller Thermistor/1 (TH1) and the Heating Roller Thermistor/2 (TH3) fails to raise a given degree of temperature even after the lapse of a given period of time after the Heating Roller Heater lamp/1 (H1) is turned ON. • The detected temperature of the Heating Roller Thermistor/1 (TH1) is lower for a given level of degree than one of the Fusing Pressure Roller Thermistor/1 (TH2) after the Front Door is opened or closed, the Main Power Switch is turned ON or TROUBLE RESET is implemented. • The counter value of zero cross signal input is not updated for a given period of time.
• Remedy: 1 Check the Fusing Unit for correct installation (whether it is secured in position). 2 Check the Fusing Unit, PWB-M and PU1 for proper connection and correct or change as necessary. 3 Change Fusing Unit. 4 Change PWB-M. 5 Change PU1.

• Code: 0501
• Description: Fusing Pressure Roller warm-up failure
  • The Fusing Pressure Roller Thermistor/1 (TH2) fails to raise a given degree of temperature even after the lapse of a given period of time after the Fusing Pressure Heater Lamp (H3) is turned ON. • The detected temperature of the Fusing Pressure Roller Thermistor/1 (TH2) is lower for a given level of degree than one of the Heating Roller Thermistor/1 (TH1) after the Front Door is opened or closed, the Main Power Switch is turned ON or TROUBLE RESET is implemented.
• Remedy: 1 Check the Fusing Unit for correct installation (whether it is secured in position). 2 Check the Fusing Unit, PWB-M and PU1 for proper connection and correct or change as necessary. 3 Change Fusing Unit. 4 Change PWB-M. 5 Change PU1.
