• 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) 22-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 is turning.
• Causes: • Fusing motor (M3) • Printer control board (PRCB)
• 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 554e 22-J bizhub 454e 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.
• Causes: • Fusing motor (M3) • Printer control board (PRCB)
• 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 554e 22-J bizhub 454e 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 is turning.
• Causes: • Paper cooling fan (FM8) • Printer control board (PRCB)
• 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.
