• Remedy: 1 Check the connector between M3-PRCB CN2 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 CN2-9 (REM) PRCB CN2-12 (LOCK) 27-I to J. 4 Replace M3. 5 Replace PRCB.

• Code: C3302
• Description: Paper cooling fan failure to turn
  The fan lock signal remains HIGH for a predetermined continuous period of time while the fan remains stationary.
• Remedy: 1 Check the connector between FM8-relay CN106- PRCB CN12 for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM8 operation check PRCB CN12-1 (REM) PRCB CN12-3 (LOCK) 26-C. 4 Replace FM8. 5 PRCB ICP3 conduction check. 6 Replace PRCB.

• Code: C3425
• Description: Fusing warm-up trouble
  • Detected temperature of the heating roller temperature sensor (TEMS) 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. • Less than the predetermined temperature of the heating roller temperature sensor (TEMS), even after a predetermined period of time after warm-up is complete.
• 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 Replace the fusing unit. 5 Replace PRCB. 6 Replace DCPU.

• Code: C3722
• Description: Fusing abnormally high temperature detection (Edge of the heating side)
  Detected temperature of the heating roller thermistor/1 (TH1) 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 and PRCB for proper connection and correct or change as necessary. 4 Replace the fusing unit. 5 Replace PRCB.

• Code: C3725
• Description: Fusing abnormally high temperature detection (Main of the heating side)
  • Detected temperature of the heating roller temperature sensor (TEMS) 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 and PRCB for proper connection and correct or change as necessary. 4 Replace the fusing unit. 5 Replace PRCB.

• Code: C3726
• Description: Fusing abnormally high temperature detection (Center of the heating side)
  Detected temperature of the heating roller thermistor/2 (TH2) 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 and PRCB for proper connection and correct or change as necessary. 4 Replace the fusing unit. 5 Replace PRCB.

• Code: C3825
• Description: Fusing abnormally low temperature detection (Main of the heating roller)
  The heating roller temperature sensor (TEMS) continues to detect a temperature lower than a predetermined one for a predetermined period of time.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the upper right door. 3 Check the fusing unit and PRCB for proper connection and correct or change as necessary. 4 Replace the fusing unit. 5 PRCB ICP15 conduction check. 6 Replace PRCB.

• Code: C3826
• Description: Fusing abnormally low temperature detection (Center of the heating roller)
  The heating roller thermistor/2 (TH2) continues to detect a temperature lower than a predetermined one for a predetermined period of time.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the open/close operation of the upper right door. 3 Check the fusing unit and PRCB for proper connection and correct or change as necessary. 4 Replace the fusing unit. 5 PRCB ICP15 conduction check. 6 Replace PRCB.
