Trouble detection condition
• C3201: Fusing motor failure to turn
• C3202: Fusing motor turning at abnormal timing
• C3201: The control circuit detects motor failure to turn while the motor is turning.
• C3202: The control circuit detects motor turning while the motor remains stationary.
• Fusing motor (M3)
• CPU board (CPUB)
• Base board (BASEB)
• 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 temperature detected by the heating roller temperature sensor (TEMS) does not shift from the pre-
standby state even after the lapse of a predetermined period of time after the completion of warm-up.
• Fusing unit
• Heating roller temperature sensor (TEMS)
• DC power supply (DCPS)
• CPU board (CPUB)
• Base board (BASEB)
• C3722: Fusing abnormally high temperature detection (Edge of the heating roller)
