• Code: C-2101
• Description: When the charge cleaning home sensor (PS41) is OFF with the main power switch (SW1) ON, PS41 does not turn ON within a specified period of time after the charge cleaning motor (M23) turns ON for home position research operation (return operation). At this time, an error detection signal (blowout of ICP) is not detected. PS41 does not turn OFF within a specified period of time after the reverse operation (return operation) is started. At this time, an error detection signal (blowout of ICP) is not detected. It is checked that the time for the M23 operations is over. The charge cleaning limit sensor (PS42) does not turn ON within a specified period of time after the reverse operation (return operation) is started for detection of PS41 being OFF. Or, PS41 does not turn ON within a specified period of time after PS42 turns ON.
• Causes: Confirmation of the wiring harness and the connector Charge cleaning motor (M23) Charge cleaning home sensor (PS41) Charge cleaning limit sensor (PS42) Printer control board (PRCB)

• Code: C-2102
• Description: The blowout of ICP for the charge cleaning motor (M23) in the printer control board (PRCB) is checked. When the charge cleaning home sensor (PS41) is OFF with the main power switch (SW1) ON, PS41 does not turn ON within a specified period of time after the M23 turns ON for home position research operation (return operation). And at this time, an error detection signal (blowout of ICP) is detected. PS41 does not turn OFF within a specified period of time after the reverse operation (return operation) is started. And at this time, an error detection signal (blowout of ICP) is detected. The charge cleaning limit sensor (PS42) does not turn ON within a specified period of time after the reverse operation (return operation) is started for detection of PS41 being OFF. Or, PS41 does not turn ON within a specified period of time after PS42 turns ON. At this time, an error detection signal (blowout of ICP) is detected.
• Causes: Confirmation of the wiring harness and the connector Charge cleaning motor (M23) Charge cleaning home sensor (PS41) Charge cleaning limit sensor (PS42) Printer control board (PRCB)

• Code: C-2103
• Description: The locking of the charge cleaning motor (M23) is detected. A motor lock signal is detected while moving from the charge cleaning limit sensor (PS42) side to the charge cleaning home sensor (PS41) side, and after a retry operation, a fifth motor lock signal is detected.
• Causes: Confirming the operation of the charging corona cleaning member Confirmation of the wiring harness and the connector Charge cleaning motor (M23) Charge cleaning home sensor (PS41) Charge cleaning limit sensor (PS42) Printer control board (PRCB)

• Code: C-2104
• Description: It is checked that the operations of the transfer/separation cleaning motor (M18) are over. When the transfer/separation cleaning home sensor (PS11) is OFF with the main power switch (SW1) ON, PS11 does not turn ON within a specified period of time after the M18 turns ON for a home position research operation (return operation). At this time, an error detection signal (blowout of ICP) is not detected. PS11 does not turn OFF within a specified period of time after the reverse operation (return operation) is started. At this time, an error detection signal (blowout of ICP) is not detected. It is checked that the operations of the M18 are over. The transfer/ separation cleaning limit sensor (PS12) does not turn ON within a specified period of time after the reverse operation (return operation) is started for detection of PS11 being OFF. Or, PS11 does not turn ON within a specified period of time after PS12 turns ON. At this time, an error detection signal (blowout of ICP) is not detected.
