Code: 56
Description: Fuser cover opened
Causes: 1 Paper eject front actuator catching on some position. 2 Eject front sensor PCB failure. 3 Main PCB failure.
Remedy: 1 Paper eject front actuator catching on some position Correct catching of the paper eject front actuator. 2 Eject front sensor PCB failure Replace the eject front sensor PCB ASSY. 3 Main PCB failure Replace the main PCB ASSY.

Code: 58
Description: Fuser unit error (Some kind of temperature error of the fuser unit occurs.)
Causes: 1 Harness connection failure between fuser unit connector and eject front sensor PCB ASSY. 2 Harness connection failure between eject front sensor PCB ASSY and main PCB ASSY. 3 Fuser unit failure. 4 Low-voltage power supply PCB failure. 5 Eject front sensor PCB failure. 6 Main PCB failure.
Remedy: 1 Harness connection failure between fuser unit connector and eject front sensor PCB ASSY Check the harness connection between the fuser unit connector and eject front sensor PCB ASSY, and reconnect it. 2 Harness connection failure between eject front sensor PCB ASSY and main PCB ASSY Check the harness connection between the eject front sensor PCB ASSY and main PCB ASSY, and reconnect it. 3 Fuser unit failure Replace the fuser unit. 4 Low-voltage power supply PCB failure Replace the low-voltage power supply PCB ASSY. 5 Eject front sensor PCB failure Replace the eject front sensor PCB ASSY. 6 Main PCB failure Replace the main PCB ASSY.

Code: 59
Description: Fuser unit error (Re-detection of fuser unit failure upon startup after the error code 58 occurs.)
Causes: 1 Harness connection failure between fuser unit connector and eject front sensor PCB ASSY. 2 Harness connection failure between eject front sensor PCB ASSY and main PCB ASSY. 3 Fuser unit failure. 4 Low-voltage power supply PCB failure. 5 Eject front sensor PCB failure. 6 Main PCB failure.
Remedy: 1 Harness connection failure between fuser unit connector and eject front sensor PCB ASSY Check the harness connection between the fuser unit connector and eject front sensor PCB ASSY, and reconnect it. 2 Harness connection failure between eject front sensor PCB ASSY and main PCB ASSY Check the harness connection between the eject front sensor PCB ASSY and main PCB ASSY, and reconnect it. 3 Fuser unit failure Replace the fuser unit. 4 Low-voltage power supply PCB failure Replace the low-voltage power supply PCB ASSY. 5 Eject front sensor PCB failure Replace the eject front sensor PCB ASSY. 6 Main PCB failure Replace the main PCB ASSY.

Code: 5B
Description: Short paper
Causes: 1 Harness connection failure of waste toner sensor. 2 Waste toner sensor failure. 3 HVPS control PCB failure. 4 Main PCB failure.
Remedy: 1 Harness connection failure of waste toner sensor Check the harness connection of the waste toner sensor and reconnect it. 2 Waste toner sensor failure Check the sensor performance following the procedure described in “Function code 32”. If any problem occurs, replace the waste toner sensor. 3 HVPS control PCB failure Replace the HVPS control PCB ASSY. 4 Main PCB failure Replace the main PCB ASSY.
