Display: Print Unable 05 Turn the power off and then back on again.
Description: When the temperature of the center thermistor of the fuser unit is higher than the idle temperature, the side thermistor of the fuser unit detected a temperature lower than the specified value.
Remedy: <User Check> • Turn OFF the power switch. After several seconds, turn ON the power again and check that this error has reset. 1 Connection failure of the center thermistor harness of the fuser unit Reconnect the center thermistor harness of the fuser unit. 2 Connection failure of the side thermistor harness Reconnect the side thermistor harness of the fuser unit. 3 Connection failure of the heater harness of the fuser unit Reconnect the heater harness of the fuser unit. 4 Connection failure of the low voltage PCB harness Reconnect the low voltage PCB harness. 5 Fuser unit failure Replace the fuser unit. 6 Low voltage power supply PCB failure Replace the low voltage power supply PCB unit. 7 Main PCB failure Replace the main PCB ASSY.
Code: 050F
Display: Print Unable 05 Turn the power off and then back on again.
Description: Detected an unknown error in the fuser unit.
Remedy: <User Check> • Turn OFF the power switch. After several seconds, turn ON the power again and check that this error has reset. 1 Connection failure of the center thermistor harness of the fuser unit Reconnect the center thermistor harness of the fuser unit. 2 Connection failure of the side thermistor harness Reconnect the side thermistor harness of the fuser unit. 3 Connection failure of the heater harness of the fuser unit Reconnect the heater harness of the fuser unit. 4 Connection failure of the low voltage PCB harness Reconnect the low voltage PCB harness. 5 Fuser unit failure Replace the fuser unit. 6 Low voltage power supply PCB failure Replace the low voltage power supply PCB unit. 7 Main PCB failure Replace the main PCB ASSY.
Code: 0900
Display: Print Unable 09 Turn the power off and then back on again.
Description: Detected irregular power supply 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 has reset. 1 Low voltage power supply PCB failure Replace the low voltage power supply PCB unit. Reset the irregular power supply detection counter after replacement. (Refer to “Resetting Irregular Power Supply Detection Counter”) 2 Main PCB failure Replace the main PCB ASSY. Note: • The irregular power supply detection error (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 unit is replaced. Ask the user to review the installation environment.
Code: 0A02
Display: Print Unable 0A Turn the power off and then back on again.
Description: The fan failure was detected.
Remedy: 1 Harness connection failure of the fan Check the harness connection of the fan and reconnect it. 2 Fan failure Replace the fan. 3 Main PCB failure Replace the main PCB ASSY.
Code: 0B01
Display: Print Unable 0B Turn the power off and then back on again.
Description: An error occurred in the high voltage power supply PCB ASSY while operating.
Remedy: 1 Connection failure of the high voltage PCB harness Reconnect the high voltage PCB harness. 2 High voltage power supply PCB failure Replace the high voltage power supply PCB ASSY. 3 Main PCB failure Replace the main PCB ASSY.
Code: 0B02
Display: Print Unable 0B Turn the power off and then back on again.
Description: An error occurred in the high voltage power supply PCB ASSY when the machine is in the ready state.
Remedy: 1 Connection failure of the high voltage PCB harness Reconnect the high voltage PCB harness. 2 High voltage power supply PCB failure Replace the high voltage power supply PCB ASSY. 3 Main PCB failure Replace the main PCB ASSY.
