• Code: C-5330
• Description: The rotation of the power supply cooling fan /3 (FM32) is checked. An abnormal condition occurs with the FM32 EM signal a specified period of time after FM32 is turned ON. This abnormal condition recurs even a specified period of time after FM32 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 Power supply cooling fan /3 (FM32) DC power supply /2 (DCPS2)

• Code: C-6101
• Description: The scanner home sensor (PS5) does not turn ON within a specified period of time after the home position search is started.
• Causes: Confirmation of the wiring harness and the connector Scanner motor (M13) Scanner home sensor (PS5) Scanner drive board (SDB) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-6301
• Description: The rotation of the scanner cooling fan (FM7) is checked, and 24V power source is also checked. An abnormal condition occurs with the FM7 EM signal a specified period of time after FM7 turns ON. This abnormal condition recurs even a specified period of time after FM7 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 Scanner cooling fan (FM7) Scanner drive board (SDB) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-6701
• Description: When processing images, a filter coefficient cannot be created normally.
• Causes: Confirmation of the wiring harness and the connector Reinstalling firmware Overall control board (OACB)

• Code: C-6702
