• Code: C-4307
• Description: The rotation of the write unit cooling fan /2 (FM8) is checked. An abnormal condition occurs with the FM8 EM signal a specified period of time after the write unit cooling fan /2 (FM8) turns ON. This abnormal condition recurs even a specified period of time after FM8 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 Write unit cooling fan /2 (FM8) AC drive board (ACDB) DC power supply /2 (DCPS2)

• Code: C-4308
• Description: When the print is started, an error detection signal of the writing section cooling fan /2 (FM8) is detected.
• Causes: Confirmation of the wiring harness and the connector Write unit cooling fan /2 (FM8) AC drive board (ACDB) DC power supply /2 (DCPS2)

• Code: C-4309
• Description: The rotation of the cooling fan /4 (FM12) is checked and the 24V power source is also checked. An abnormal condition occurs with the FM12 EM signal a specified period of time after FM12 turns ON. This abnormal condition recurs even a specified period of time after FM12 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 Cooling fan /4 (FM12) AC drive board (ACDB) DC power supply /2 (DCPS2)

• Code: C-4310
• Description: The blowout of ICP for the cooling fan /4 (FM12) in the AC drive board (ACDB) is checked. An abnormal condition occurs with the FM12 EM signal a specified period of time after FM12 turns ON. This abnormal condition recurs even a specified period of time after FM12 is turned OFF and then turned ON, and an error detection signal (blowout of ICP) is detected.
• Causes: Confirmation of the wiring harness and the connector Cooling fan /4 (FM12) AC drive board (ACDB) DC power supply /2 (DCPS2)

• Code: C-4311
• Description: Rotation of the cooling fan /4 (FM12) is checked. An abnormal condition occurs with the FM12 EM signal a specified period of time after FM12 turns ON. This abnormal condition recurs even a specified period of time after FM12 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 Cooling fan /4 (FM12) AC drive board (ACDB) DC power supply /2 (DCPS2)

• Code: C-4312
• Description: The rotation of the polygon cooling fan (FM9) is checked and the 24V power source is also checked. An abnormal condition occurs with the FM9 EM signal a specified period of time after FM9 is turned ON. This abnormal condition recurs even a specified period of time after FM9 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 Polygon cooling fan (FM9) AC drive board (ACDB) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-4313
• Description: The blowout of ICP for the polygon cooling fan (FM9) in the AC drive board (ACDB) is checked. An abnormal condition occurs with the FM9 EM signal a specified period of time after FM9 turns ON. This abnormal condition recurs even a specified period of time after FM9 is turned OFF and then turned ON, and an error detection signal (blowout of ICP) is detected.
• Causes: Confirmation of the wiring harness and the connector Polygon cooling fan (FM9) AC drive board (ACDB) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-4314
• Description: The rotation of the polygon cooling fan (FM9) is checked. An abnormal condition occurs with the FM9 EM signal a specified period of time after FM9 turns ON. This abnormal condition recurs even a specified period of time after FM9 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 Polygon cooling fan (FM9) AC drive board (ACDB) Printer control board (PRCB) DC power supply /2 (DCPS2)
