User Check
• Check if the paper is jammed. If jammed, remove it.
• Check if the fuser cover is closed certainly.
Step Cause Remedy
1
Harness connection failure of
registration front sensor PCB
ASSY, paper eject sensor PCB
ASSY or registration rear sensor
PCB ASSY
Check the harness connections of the
registration front sensor PCB ASSY, paper
eject sensor PCB ASSY or registration rear
sensor PCB ASSY, and reconnect them.
2

registration rear actuator or paper
eject actuator catching on some
position
Correct catching of the registration front
actuator, registration rear actuator or paper
eject actuator.
3a
