  • The motor lock signal remains LOW for a predetermined continuous period of time while the motor remains stationary
• Remedy: 1 Check the M5 connector for proper connection and correct as necessary. 2 Check the loading status of the fusing unit drive, and correct the error as necessary. 3 Check the fusing unit, PRCB for proper connection and correct or change as necessary. 4 M5 operation check. 5 Change M5. 6 Change PRCB.

• Code: C3301
• Description: Fusing cooling fan motor/ 1 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 M5 connector for proper connection and correct as necessary. 2 Check the loading status of the fusing unit drive, and correct the error as necessary. 3 Check the fusing unit, PRCB for proper connection and correct or change as necessary. 4 M5 operation check. 5 Change M5. 6 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 M5 connector for proper connection and correct as necessary. 2 Check the loading status of the fusing unit drive, and correct the error as necessary. 3 Check the fusing unit, PRCB for proper connection and correct or change as necessary. 4 M5 operation check. 5 Change M5. 6 Change PRCB.

• Code: C3303
• Description: Fusing cooling fan motor/ 1 failure to turn
• Remedy: 1 Check the FM9 connector for proper connection and correct as necessary. 2 Check the fan for possible overload and correct as necessary. 3 FM9 operation check. 4 Change FM9. 5 Change PRCB.

• Code: C3421
• Description: Fusing heaters trouble (heating side)
  • The temperature detected by the heating roller thermistor/C does not reach a predetermined level after the lapse of a predetermined period of time after the heating roller fusing heater lamp lights up. • The difference between the maximum and minimum temperatures detected by the heating roller thermistor/C within a predetermined period of time after the start of a warm-up cycle is below or above a predetermined value. • The temperature detected after a pressure level correction remains under a predetermined level even after the lapse of a predetermined period of time after the start of the temperature detection. • During a warm-up, a zero cross signal cannot be detected after the lapse of a predetermined period of time after the fusing heater is turned ON or OFF.
• 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, PRCB and DCPU for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change PRCB. 6 Change DCPU.

• Code: C3423
• Description: Fusing heaters trouble (pressurizing side)
  • After warm-up operation starts, the fusing pressure roller thermistor does not detect a temperature as high as a predetermined one though a predetermined period of time has elapsed. • The temperature of the pressure roller remains lower than a predetermined level even after the lapse of a predetermined period of time after a temperature correction.
• 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, PRCB and DCPU for proper connection and correct or change as necessary. 4 Change fusing unit. 5 Change PRCB. 6 Change DCPU.

• Code: C3461
• Description: Release new fusing unit
  • A new installation is not detected when a new fusing Unit is installed.
• Remedy: 1 Check the fusing unit for correct installation (whether it is secured in position). 2 Check the fusing unit, PRCB for proper connection and correct or change as necessary. 3 Reinstall fusing unit. 4 Change fusing unit. 5 Change PRCB.
