• Code: C-2811
• Description: The data is defective. While in the drum potential correction, no convergence is obtained even after correction is made more than 10 times. When this condition is detected 5 times in succession, the error code is displayed.
• Causes: Confirmation of the wiring harness and the connector Drum potential sensor board (DPSB) Drum potential sensor (DPS) Printer control board (PRCB)

• Code: C-2812#
• Description: Auto adjustment monitor value abnormality. No convergence is made in the auto adjustment of the transfer current.
• Causes: Confirmation of the transfer/ separation charger power feeding contact Confirmation of the wiring harness and the connector High voltage unit /2 (HV2) Printer control board (PRCB) ADU drive board (ADUDB)

• Code: C-2813#
• Description: Auto adjustment monitor value abnormality. No convergence is made in the auto adjustment of the separation (AC) current.
• Causes: Confirmation of the transfer/ separation charger power feeding contact Confirmation of the wiring harness and the connector High voltage unit /2 (HV2) Printer control board (PRCB) ADU drive board (ADUDB)

• Code: C-2814#
• Description: Auto adjustment monitor value abnormality. No convergence is made in the auto adjustment of the separation (DC) current.
• Causes: Confirmation of the transfer/ separation charger power feeding contact Confirmation of the wiring harness and the connector High voltage unit /2 (HV2) Printer control board (PRCB) ADU drive board (ADUDB)

• Code: C-2815#
• Description: Auto adjustment monitor value abnormality. No convergence is made in the auto adjustment of the developing bias.
• Causes: Confirmation of the charger power feeding contact Confirmation of the wiring harness and the connector High voltage unit /1 (HV1) Printer control board (PRCB)

• Code: C-3101
• Description: The blowout of ICP for the web motor (M16) in the printer control board (PRCB) is checked, and the 24V power source is also checked. When M16 turn ON from OFF, error detection signals (blowout of ICP and the 24V cut off) are detected.
• Causes: Confirmation of the wiring harness and the connector Web motor (M16) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-3102
• Description: The blowout of ICP for the web motor (M16) in the printer control board (PRCB) is checked. When M16 turns ON from OFF, the blowout of ICP abnormality is detected with a 24V down signal normal.
• Causes: Confirmation of the wiring harness and the connector Web motor (M16) Printer control board (PRCB) DC power supply /2 (DCPS2)

• Code: C-3301
• Description: The rotation of the fusing fan /1 (FM1) is checked, and the 24V power source is also 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) is detected.
• Causes: Confirmation of the wiring harness and the connector Fusing fan /1 (FM1) ADU drive board (ADUDB) DC power supply /2 (DCPS2)
