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.
Code: 6D
Description: Fuser unit error. (The center thermistor detects 60°C or lower temperature for 1 second during standby or printing.)
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: 6F
Description: Fuser unit error. (The center and side thermistors detect extremely high temperature.) (Detection of hardware)
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.
