Step Cause Remedy
1
Eject actuator attachment
failure
Reattach the eject actuator.
2
Eject actuator spring
attachment failure
Reattach the eject actuator spring.
3
Eject actuator and/or fuser
cover failure
Replace the fuser cover.
4
Eject sensor PCB failure Refer to "1.3.10 Check sensor operation
(function code: 32)" in Chapter 5 to check the
sensor operation. If the sensor operation is
faulty, replace the eject sensor PCB ASSY.
5 Main PCB failure Replace the main PCB ASSY.
