Display: Print Unable 09 Turn the power off and then back on again.
Description: Detected irregular power supply more than 100 times.
Remedy: 1 Low voltage power supply PCB failure Replace the low voltage power supply PCB unit. Reset the irregular power supply detection counter after replacement. 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: 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.
Code: 4000
Display: Drum End Soon
Description: The number of rotations of the drum unit is reaching the upper limit.
Remedy: 1 Replace the drum unit with a new one and reset the drum counter. If the error display is not cleared, the main PCB is faulty. Replace the main PCB ASSY.
Code: 4200
Display: Replace Drum
Description: The number of rotations of the drum unit has reached the life limit. (Printing does not stop.)
Remedy: 1 Replace the drum unit with a new one and reset the drum counter. If the error display is not cleared, the main PCB is faulty. Replace the main PCB ASSY.
Code: 4B01
Display: Toner Low Prepare New Toner Cartridge.
Description: Dot counter or developer roller counter of the toner is reaching the upper limit (when setting toner stop mode).
Remedy: 1 Connection failure of the new toner sensor PCB harness Reconnect the new toner sensor PCB harness. 2 Connection failure of the motor encoder PCB flat cable Reconnect the motor encoder PCB flat cable. 3 New toner sensor PCB failure Replace the new toner sensor PCB ASSY. 4 Motor encoder PCB failure Replace the motor encoder PCB ASSY. 5 Main PCB failure Replace the main PCB ASSY.
