• Code: C3101
• Description: Fusing roller separation failure
  • With the fusing roller being retracted, the fusing pressure home sensor (PS38) is not unblocked even after the specified period of time has passed after the fusing pressure motor (M11) started rotating. • With the fusing roller being pressed, the fusing pressure home sensor (PS38) is not blocked even after the specified period of time has passed after the fusing pressure motor (M11) started rotating.
• Remedy: 1 Check the connector between M11-relay CN112- PRCB CN13 for proper connection and correct as necessary. 2 Check the connector between fusing unit-relay CN95, CN96-PRCB CN4 for proper connection and correct as necessary. (bizhub C554). Check the connector between fusing unit-relay CN98, CN99, CN104-PRCB CN5 for proper connection and correct as necessary. (bizhub C454) 3 PS38 I/O check, sensor check PRCB CN4-9 (ON) (bizhub C554) PRCB CN5-12 (ON) (bizhub C454) - 4 M11 operation check PRCB CN13-1 to 4 bizhub C554 26-C bizhub C454 24-C. 5 Replace M11. 6 Replace the fusing unit (bizhub C554/bizhub C454). 7 PRCB IC26 conduction check. 8 Replace PRCB.

• Code: C3102
• Description: Heating roller assy failure to turn
  The hard latch signal from one or both of the heating roller rotation latch detection 1 and the heating roller rotation latch detection 2 is turned ON.
• Remedy: 1 Check the fusing unit for proper installation and correct as necessary. 2 Check the connector between M3-PRCB CN2 for proper connection and correct as necessary. 3 Check the connector of M3 for proper drive coupling and correct as necessary. 4 PS37 I/O check, sensor check. 5 M3 operation check PRCB CN2-9 (REM) PRCB CN2-12 (LOCK) bizhub C554 22-J bizhub C454 21-J. 7 Replace M3. 8 Replace the fusing unit. 9 Replace 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 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) bizhub C554 22-J bizhub C454 21-J. 4 Replace M3. 5 Replace 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 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) bizhub C554 22-J bizhub C454 21-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) 28-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:

• 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, IHPU (bizhub C554 only) and PRCB for proper connection and correct or change as necessary. 4 Replace the fusing unit (bizhub C554/bizhub C454). 5 Replace IHPU (bizhub C554 only). 6 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.d
• 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, IHPU (bizhub C554 only) and PRCB for proper connection and correct or change as necessary. 4 Replace the fusing unit (bizhub C554/bizhub C454). 5 Replace IHPU (bizhub C554 only). 6 Replace PRCB.
