• Code: 57
• Description: Paper is jammed in the duplex paper feed path.
• Causes: • Install the duplex tray properly. • Check if the paper is jammed in the duplex tray.
• Remedy: 1 Foreign object around duplex tray Remove the foreign object around the duplex tray. 2 Duplex tray failure Replace the duplex tray. 3 DX gears damaged Replace the main frame L ASSY.

• Code: 58
• Description: Fuser unit error. (Some kind of fixing error occurs) (Warning)
• Causes: • Turn OFF the power switch, and turn it ON again after a while.
• Remedy: 1 Any fuser error occurs when started in the ready state. Follow the “Remedy” of the error code that has reoccurred.

• Code: 59
• Description: Fuser unit error. (After the error code58 occurred, a failure in the fuser unit is detected again upon start-up.)
• Causes: The center thermistor of fuser unit detects error.
• Remedy: 1 Harness connection failure between fuser unit connector and paper eject sensor PCB ASSY Check the harness connection between the fuser unit connector and paper eject sensor PCB ASSY, and reconnect it. 2 Harness connection failure between fuser unit connector and low voltage power supply PCB ASSY Check the harness connection between the fuser unit connector and low voltage power supply PCB ASSY, and reconnect it. 3 Harness connection failure between paper eject sensor PCB and main PCB Check the harness connection between the paper eject sensor PCB and main PCB, and reconnect it. 4 Paper eject sensor PCB failure Replace the paper eject sensor PCB ASSY. 5 Low voltage power supply PCB failure Replace the low voltage power supply PCB ASSY. 6 Main PCB failure Replace the main PCB ASSY. 7 Fuser unit failure Replace the fuser unit.

• Code: 63
• Description: The toner cartridge is at the end of life.
• Causes: • Replace a new toner cartridge. • Press the [MENU] button. Next, press the [1] button and [8] button to clear the stop mode*, and shift to the continue mode
• Remedy: 1 New toner actuator catching on some position Correct the position of the new toner actuator. 2 Harness connection failure of new toner sensor PCB Check the harness connection of the new toner sensor PCB and reconnect it. 3 New toner sensor PCB failure Replace the new toner sensor PCB. 4 Main PCB failure Replace the main PCB ASSY.

• Code: 67
• Description: The toner cartridge will reach the end of life.
• Causes: • Prepare a new toner cartridge.
• Remedy: 1 New toner actuator catching on some position Correct the position of the new toner actuator. 2 Harness connection failure of new toner sensor PCB Check the harness connection of the new toner sensor PCB and reconnect it. 3 New toner sensor PCB failure Replace the new toner sensor PCB. 4 Main PCB failure Replace the main PCB ASSY.

• Code: 6A
• Description: Fuser unit error. (The center thermistor does not detect 60°C within in the specified time.)
• Causes:
• Remedy: 1 Fuser unit connector connection failure Check the connector connection of the fuser unit and reconnect it. 2 Fuser unit failure Replace the fuser unit. 3 Low voltage power supply PCB failure Replace the low voltage power supply PCB ASSY. 4 Paper eject sensor PCB failure Replace the paper eject sensor PCB ASSY. 5 Main PCB failure Replace the main PCB ASSY.

• Code: 6B
• Description: Fuser unit error. (The center thermistor does not detect 100°C within in the specified time.)
• Causes:
• Remedy: 1 Fuser unit connector connection failure Check the connector connection of the fuser unit and reconnect it. 2 Fuser unit failure Replace the fuser unit. 3 Low voltage power supply PCB failure Replace the low voltage power supply PCB ASSY. 4 Paper eject sensor PCB failure Replace the paper eject sensor PCB ASSY. 5 Main PCB failure Replace the main PCB ASSY.

• Code: 6C
• Description: Fuser unit error. (The center thermistor detects 270°C or higher temperature for 1 second.)
• Causes:
• Remedy: 1 Fuser unit connector connection failure Check the connector connection of the fuser unit and reconnect it. 2 Fuser unit failure Replace the fuser unit. 3 Low voltage power supply PCB failure Replace the low voltage power supply PCB ASSY. 4 Paper eject sensor PCB failure Replace the paper eject sensor PCB ASSY. 5 Main PCB failure Replace the main PCB ASSY.
