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 front actuator,
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
Paper eject sensor PCB failure Check the sensor performance following
the procedure in "Factory Inspection Mode"
(Chapter 5). If any problem occurs, replace
the eject sensor PCB ASSY.
3b
Registration front sensor PCB
failure
Check the sensor performance following
the procedure in "Factory Inspection Mode"
(Chapter 5). If any problem occurs, replace
the registration front sensor PCB ASSY.
3c
Registration rear sensor PCB
failure
Check the sensor performance following
the procedure in "Factory Inspection Mode"
(Chapter 5). If any problem occurs, replace
the registration rear sensor PCB ASSY.
4 Toner LED PCB failure Replace the toner LED PCB ASSY.
