• Code: C3101
• Description: Fusing roller separation failure
  • With the fusing roller being retracted, the pulse of the encoder sensor does not change even after the specified period of time has passed after the fusing pressure roller retraction motor started rotating. • With the fusing roller being pressed, the encoder pulse sensor does not change even after the specified period of time has passed after the fusing pressure roller retraction motor started rotating. • With the pressure roller being pressed, the fusing pressure roller home sensor did not turn ON (pressed) even after the fusing pressure roller retraction sensor counted up the specified number of pulse after the fusing pressure roller retraction motor started rotating.
• Remedy: 1 Check the connector between M11-PRCB CN3 for proper connection and correct as necessary. 2 Check the connector between PS32-PRCB CN3 for proper connection and correct as necessary. 3 Check the connector between fusing unit- PRCB CN12 for proper connection and correct as necessary. 4 PS32 I/O check, sensor check PRCB CN3-9 (ON) C-13 5 M11 operation check PRCB CN3-5 to 6 C-13. 6 Change M11. 7 Change fusing unit. 8 PRCB ICP6 conduction check. 9 Change PRCB.

• Code: C3201
• Description: Fusing motor failure to turn
  • The motor lock signal remains HIGH for a predetermined continuous period of time while the motor remains stationary.
• Remedy: 1 Check the connector between M3-PRCB CN11 for proper connection and correct as necessary. 2 Check the loading status of the fusing unit drive, and correct the error as necessary. 3 M3 operation check PRCB CN11-9 (REM) PRCB CN11-12 (LOCK) J-6. 4 Change M3. 5 Change PRCB.

• Code: C3202
• Description: Fusing motor turning at abnormal timing
  • The motor lock signal remains LOW for a predetermined continuous period of time while the motor remains stationary.
• Remedy: 1 Check the connector between M3-PRCB CN11 for proper connection and correct as necessary. 2 Check the loading status of the fusing unit drive, and correct the error as necessary. 3 M3 operation check PRCB CN11-9 (REM) PRCB CN11-12 (LOCK) J-6. 4 Change M3. 5 Change PRCB.

• Code: C3302
• Description: Fusing cooling fan motor/ 2,3 failure to turn
  • The fan motor lock signal remains HIGH for a predetermined continuous period of time while the motor remains stationary.
• Remedy: 1 Check the connector between FM5-relay CN11-relay CN9-PRCB CN9 for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM5 operation check PRCB CN9-17 (LOCK) J-12 4 Change FM5. 5 Change PRCB.

• Code: C3421
• Description: Fusing heaters trouble (Heating side)
  • Detected temperature of the heating roller thermistor/C does not go up a given range of temperature even after a lapse of given period of time at warm up. • Detected temperature of the heating roller thermistor/C does not reach to a given temperature even after a lapse of given period of time 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, DCPU and PRCB for proper connection and correct or change as necessary. 4 Change fusing unit. 6 Change PRCB. 7 Change DCPU.

• Code: C3423
• Description: Fusing heaters trouble (Pressurizing side)
  • Detected temperature of the pressure roller thermistor does not go up a given range of temperature even after a lapse of given period of time at warm up. • Detected temperature of the pressure roller thermistor does not reach to a given temperature even after a lapse of given period of time 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, DCPU and PRCB for proper connection and correct or change as necessary. 4 Change fusing unit. 6 Change PRCB. 7 Change DCPU.

• Code: C3721
• Description: Fusing abnormally high temperature detection (Center of the heating side)
  • Detected temperature of the heating roller thermistor/C goes beyond a given temperature for a given period of time consecutively. • Detected temperature of the heating roller thermistor/M goes beyond a given temperature for a given period of time consecutively. • The hard protector signal error is detected 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, DCPU and PRCB for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change PRCB. 6 Change DCPU.

• Code: C3722
• Description: Fusing abnormally high temperature detection (Edge of the heating side)
  • Detected temperature of the heating roller thermistor/S 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, DCPU and PRCB for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change PRCB. 6 Change DCPU.
