Code :

Code: C-3302
Description: Rotation of the fusing fan /1 (FM1) is checked. An abnormal condition occurs with the FM1 EM signal a specified period of time after FM1 is turned ON. This abnormal condition recurs even a specified period of time after FM1 is turned OFF and then turned ON, and an error detection signal (24V cut off/ blowout of ICP) is not detected.
Causes: Confirmation of the wiring harness and the connector Fusing fan /1 (FM1) ADU drive board (ADUDB) DC power supply /2 (DCPS2)

Code: C-3303#
Description: When the print is completed, the fusing fan /1 (FM1) EM signal gets into an abnormal condition.
Causes: Confirmation of the wiring harness and the connector Fusing fan /1 (FM1) ADU drive board (ADUDB) DC power supply /2 (DCPS2)

Code: C-3304
Description: The rotation of the fusing fan /2 (FM4) is checked, and the 24V power source is also checked. An abnormal condition occurs with the FM4 EM signal a specified period of time after FM4 is turned ON. This abnormal condition recurs even a specified period of time after FM4 is turned OFF and then turned ON, and an error detection signal (24V cut off) is detected.
Causes: Confirmation of the wiring harness and the connector Fusing fan /2 (FM4) ADU drive board (ADUDB) DC power supply /2 (DCPS2)

Code: C-3305
Description: Rotation of the fusing fan /2 (FM4) is checked. An abnormal condition occurs with the FM4 EM signal a specified period of time after FM4 is turned ON. This abnormal condition recurs even a specified period of time after FM4 is turned OFF and then ON again, and an error detection signal (24V cut off) is not detected.
Causes: Confirmation of the wiring harness and the connector Fusing fan /2 (FM4) ADU drive board (ADUDB) DC power supply /2 (DCPS2)

Code: C-3306
Description: When the print is completed, the fusing fan /2 (FM4) EM signal gets into an abnormal condition.
Causes: Confirmation of the wiring harness and the connector Fusing fan /2 (FM4) ADU drive board (ADUDB) DC power supply /2 (DCPS2)

Code: C-3501
Description: Fusing roller /Up high temperature detection (software). TH1 detects a temperature of 235°C or above 5 times in a specified period of time. Or, the fusing temperature sensor /2 (TH2) detects a temperature of 240°C or above.
Causes: Confirmation of the wiring harness and the connector Fusing temperature sensor / 1 (TH1) Fusing heater lamp /1 (L1) Fusing heater lamp /2 (L2) Printer control board (PRCB) AC drive board (ACDB)

Code: C-3502
Description: Fusing heating roller high temperature abnormality (software). TH3 detects a temperature of 230°C or above 5 times in a specified period of time.
Causes: Confirmation of the wiring harness and the connector Fusing temperature sensor / 3 (TH3) Fusing heater lamp /3 (L3) Printer control board (PRCB) AC drive board (ACDB)

Code: C-3503
Description: Fusing roller /Up high temperature abnormality (hardware). An abnormal condition is detected with the fusing error detection signal 1.
Causes: Confirmation of the wiring harness and the connector Fusing temperature sensor / 1 (TH1) Fusing heater lamp /1 (L1) Fusing heater lamp /2 (L2) Printer control board (PRCB) AC drive board (ACDB)
