Description: An error occurred in the internal temperature sensor.
Remedy: 1 Connection failure of the internal temperature sensor harness Reconnect the internal temperature sensor harness. 2 Connection failure of the eject sensor harness Reconnect the eject sensor harness. 3 Eject sensor PCB failure Replace the eject sensor PCB. 4 Main PCB failure Replace the main PCB.
Code: 0900
Description: Detected irregular power supply for more than 100 times.
Remedy: <User Check> • Turn OFF the power switch. After several seconds, turn ON the power again and check that this error is reset. 1 Low-voltage power supply PCB failure Replace the low-voltage power supply PCB. Refer to “Reset counters for consumable parts (Function code 88)” to reset the irregular power supply detection counter after the replacement. 2 Main PCB failure Replace the main PCB. Note: The irregular power supply detection error (Error code 0900) of the low-voltage power supply PCB occurs when there is a large distortion in the power supply voltage supplied to the machine. In this case, if the same power supply is used, the same error might occur again even if the low-voltage power supply PCB is replaced. For this reason, be sure to ask the user to rearrange the installation environment.
Code: 0A02
Description: Main PCB detected the fan failure.
Remedy: 1 Connection failure of the fan harness Reconnect the fan harness. 2 Connection failure of the highvoltage power supply flat cable Reconnect the high-voltage power supply flat cable. 3 Fan failure Replace the fan. 4 High-voltage power supply PCB failure Replace the high-voltage power supply PCB. 5 Main PCB failure Replace the main PCB.
Code: 0B01
Description: An error occurred in the high-voltage power supply PCB while operating.
Remedy: <User Check> • Slide the green tab of the drum unit to left and right for two to three times to clean the corona wire for all the four colors. • There is a possibility of condensation. Turn the power switch OFF and ON, then open the top cover and the back cover and leave the machine more than 30 minutes. • Replace the drum unit. 1 Dirt on the machine, the drum unit, the belt unit and the waste toner box terminal. Clean the machine, the drum unit, the belt unit and the waste toner box terminal. 2 Connection failure of the highvoltage power supply flat cable Reconnect the high-voltage power supply flat cable. 3 High-voltage power supply PCB failure Replace the high-voltage power supply PCB. 4 Main PCB failure Replace the main PCB.
Code: 0B02
Description: An error occurred in the high-voltage power supply PCB when the machine was in the ready state.
Remedy: <User Check> • Slide the green tab of the drum unit to left and right for two to three times to clean the corona wire for all the four colors. • There is a possibility of condensation. Turn the power switch OFF and ON, then open the top cover and the back cover and leave the machine more than 30 minutes. • Replace the drum unit. 1 Dirt on the machine, the drum unit, the belt unit and the waste toner box terminal. Clean the machine, the drum unit, the belt unit and the waste toner box terminal. 2 Connection failure of the highvoltage power supply flat cable Reconnect the high-voltage power supply flat cable. 3 High-voltage power supply PCB failure Replace the high-voltage power supply PCB. 4 Main PCB failure Replace the main PCB.
Code: 0C00
Description: An error occurred in the density sensor.
Remedy: 1 Connection failure of the registration mark sensor L harness Reconnect the registration mark sensor L harness. 2 Eject sensor PCB failure Replace the eject sensor PCB. 3 Registration mark sensor L PCB failure Replace the registration mark sensor L PCB. 4 Main PCB failure Replace the main PCB.
