Display: Print Unable ZC Turn the power off and then back on again.
Description: Detected irregular power supply less than 100 times.
Remedy: • 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 unit. 2 Main PCB failure Replace the main PCB ASSY.
Code: 7000
Display: Jam Inside 1 Open the Scanner Cover and Top Cover, pull out the Drum Unit and remove the jammed paper, then press Start.
Description: The eject sensor does not detect paper pass after the paper printing position sensor detected the paper pass.
Remedy: • Remove the jammed paper. • Check that the paper is set in the paper tray correctly. • Check that there is not too much paper set in the paper tray. • Flip over the paper in the paper tray or rotate the paper 180 degrees. • Check that the thickness of the paper is within the standard. • Flip through the paper and reset it in the paper tray. 1 Foreign object inside the machine Remove the foreign object. 2 Eject actuator coming off or caught in sections of the machine Reattach the eject actuator. 3 Connection failure of the paper feed/paper printing position sensor PCB harness Reconnect the paper feed/paper printing position sensor PCB harness. 4 Connection failure of the eject sensor PCB harness Reconnect the eject sensor PCB harness. 5 Paper feed/paper printing position sensor PCB failure Replace the paper feed/paper printing position sensor PCB ASSY. 6 Eject sensor failure Replace the eject sensor PCB ASSY. 7 Main PCB failure Replace the main PCB ASSY.
Code: 7100
Display: Jam Inside 2 Open the Scanner Cover and remove the jammed paper, then press Start.
Description: The eject sensor remains ON (paper pass detected) even after the paper printing position sensor detected the end of paper pass.
Remedy: • Remove the jammed paper. • Check that the paper is set in the paper tray correctly. • Check that there is not too much paper set in the paper tray. • Flip over the paper in the paper tray or rotate the paper 180 degrees. • Check that the thickness of the paper is within the standard. • Flip through the paper and reset it in the paper tray. 1 Foreign object in the rear of the machine Remove the foreign object. 2 Eject actuator caught in sections of the machine Reattach the eject actuator. 3 Paper feed/paper printing position sensor PCB failure Replace the paper feed/paper printing position sensor PCB ASSY. 4 Eject sensor failure Replace the eject sensor PCB ASSY. 5 Main PCB failure Replace the main PCB ASSY.
Code: 7300
Display: Jam Tray Remove the jammed paper from Tray, then press Start.
Description: The paper feed sensor does not detect paper pass even after the paper has been fed for the specified time.
Remedy: • Remove the jammed paper. • Check that the paper is set in the paper tray correctly. • Check that there is not too much paper set in the paper tray. • Flip over the paper in the paper tray or rotate the paper 180 degrees. • Check that the thickness of the paper is within the standard. • Check that the size of the paper is within the standard. • Flip through the paper and reset it in the paper tray. 1 Foreign object in the front of the machine Remove the foreign object. 2 Gears around the plate up plate coming off Reattach gears around the plate up plate. 3 Attachment failure of the motor drive belt Reattach the motor drive belt. 4 Attachment failure of the laser shutter arm Reattach the laser shutter arm. 5 Connection failure of the main motor harness Reconnect the main motor harness. 6 Connection failure of the motor encoder PCB flat cable Reconnect the motor encoder PCB flat cable. 7 Connection failure of the pickup solenoid harness Reconnect the pick-up solenoid harness. 8 Motor drive belt failure Replace the motor drive belt. 9 Motor encoder PCB failure Replace the motor encoder PCB ASSY. 10 Low voltage power supply PCB failure Replace the low voltage power supply PCB unit. 11 Laser unit failure Replace the laser unit. 12 Main PCB failure Replace the main PCB ASSY.
Code: 7D00
Display: Jam Inside 3 Remove the jammed paper, then press Start.
Description: When the power switch was turned ON, the eject sensor detected paper pass. (Cannot determine whether the top cover is open or whether it is a paper jam.)
Remedy: 1 Eject actuator caught in sections of the machine Reattach the eject actuator. 2 Paper feed/paper printing position sensor PCB failure Replace the paper feed/paper printing position sensor PCB ASSY. 3 Eject sensor failure Replace the eject sensor PCB ASSY. 4 Main PCB failure Replace the main PCB ASSY.
Code: 7E00
Display: Jam Tray Remove the jammed paper from Tray, then press Start.
Description: Detected that multiple paper is fed five times in a row during receiving fax or printing list/ report.
Remedy: • Remove the jammed paper. • Check that the paper is set in the paper tray correctly. • Check that there is not too much paper set in the paper tray. • Check that the thickness of the paper is within the standard. • Check that the size of the paper is within the standard. • Flip through the paper and reset it in the paper tray. 1 Main PCB failure Replace the main PCB ASSY.
