Description: When the center thermistor of the fuser unit was lower than the idle temperature, the side thermistor detected a temperature higher than the specified temperature.
Remedy: <User Check> • Turn OFF the power switch. After several seconds, turn ON the power again and check that this error is reset. 1 Connection failure of the center or side thermistor harness of the fuser unit Reconnect the center or side thermistor harness of the fuser unit. 2 Connection failure of the fuser unit heater harness Reconnect the fuser unit heater harness. 3 Connection failure of the eject sensor PCB flat cable Reconnect the eject sensor PCB flat cable. 4 Connection failure of the LVPS harness Reconnect the LVPS harness. 5 Eject sensor PCB failure Replace the eject sensor PCB ASSY. 6 Fuser unit failure Replace the fuser unit. 7 Low-voltage power supply PCB failure Replace the low-voltage power supply PCB ASSY. 8 Main PCB failure Replace the main PCB ASSY.

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 ASSY. Reset irregular power supply detection counter of low-voltage power supply PCB (function code: 88) in Chapter 5 to reset the irregular power supply detection counter. 2 Main PCB failure Replace the main PCB ASSY. Note: • The irregular power supply detection error of the low-voltage power supply PCB (error code: 0900) 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 may occur even when the low-voltage power supply PCB ASSY is replaced. Ask the user to review the installation environment.
