• Code: C-0301
• Description: The rotation of the conveyance suction fan (FM2) is checked, and the 24V power source is also checked. An abnormal FM2 EM signal condition occurs a specified period of time after FM2 is turned 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 Conveyance suction fan (FM2) AC drive board (ACDB) DC power supply /2 (DCPS2)

• Code: C-0302
• Description: The blowout of ICP for the conveyance suction fan (FM2) in the AC drive board (ACDB) is checked. An abnormal condition occurs with the FM2 EM signal a specified period of time after FM2 is turned ON. This abnormal condition recurs even a specified period of time after FM2 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 Conveyance suction fan (FM2) AC drive board (ACDB) DC power supply /2 (DCPS2)

• Code: C-0303
• Description: The rotation of the conveyance suction fan (FM2) is checked. An abnormal condition occurs with the FM2 EM signal a specified period of time after FM2 is turned ON. This abnormal condition recurs even a specified period of time after FM2 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 Conveyance suction fan (FM2) AC drive board (ACDB) DC power supply /2 (DCPS2)

• Code: C-0304
• Description: Rotation of paper exit cooling fan /Lw1 (FM13), /Lw2 (FM14) is checked. An abnormal condition occurs with the FM13, FM14 EM signal a specified period of time after FM 13, FM14 is turned ON. This abnormal condition is detected even a specified period of time after FM13, FM14 is turned OFF and then turned ON.
• Causes: Confirmation of the wiring harness and the connector Paper exit cooling fan /Lw1 (FM13) Paper exit cooling fan /Lw2 (FM14) Printer control board (PRCB)

• Code: C-0305
• Description: Rotation of paper exit cooling fan /Up1 (FM15), /Up2 (FM17) is checked. An abnormal condition occurs with the FM15, FM17 EM signal a specified period of time after FM 15, FM17 is turned ON. This abnormal condition is detected even a specified period of time after FM15, FM17 is turned OFF and then turned ON.
• Causes: Confirmation of the wiring harness and the connector Paper exit cooling fan /Up1 (FM15) Paper exit cooling fan /Up2 (FM17) Printer control board (PRCB)

• Code: C-0306
• Description: The blowout of ICP for the paper exit cooling fans /Lw1 (FM13), / Lw2 (FM14), /Up1 (FM15) and / Up2 (FM17) is detected. An abnormal condition occurs either with the FM13 EM signal and the FM14 EM signal a specified period of time after FM13 and FM14 are turned ON or with the FM15 EM signal and the FM17 EM signal a specified period of time after FM15 and FM17 are turned ON. With this abnormal condition, an error detection signal (blowout of ICP) is detected and the door close is detected 5 times in succession.
• Causes: Confirmation of the wiring harness and the connector Paper exit cooling fan /Lw1 (FM13) Paper exit cooling fan /Lw2 (FM14) Paper exit cooling fan /Up1 (FM15) Paper exit cooling fan /Up2 (FM17) Printer control board (PRCB)

• Code: C-0307
• Description: The rotation of the developing cooling fan (FM19) is checked, and the 24V power source is also checked. An abnormal condition occurs with the FM19 EM signal a specified period of time after FM19 is turned ON. This abnormal condition recurs even a specified period of time after FM is turned OFF and then ON again, and an error detection signal (24V cut off) is detected.
• Causes: Confirmation of the wiring harness and the connector DC power supply /2 (DCPS2) Printer control board (PRCB)

• Code: C-0308
• Description: The blowout of ICP for the developing cooling fan (FM19) is checked. An abnormal condition occurs with the FM19 EM signal a specified period of time after FM19 is turned ON. This abnormal condition recurs even a specified period of time after FM is turned OFF and then ON again, and an error detection signal (blowout of ICP) is detected. However, an error detection signal (24V cut off) is not detected.
• Causes: Confirmation of the wiring harness and the connector DC power supply /2 (DCPS2) Printer control board (PRCB)
