Cause
3-19
Remedy
Check the harness connections of the
High-Voltage PS PCB ASSY or relay rear
PCB ASSY, and reconnect them.
Correct catching of the registration front
actuator, registration rear actuator or paper
eject actuator.
Check the harness connection of the
registration solenoid, and reconnect it.
Check the sensor performance following
the procedure in "Factory Inspection Mode"
in 1.3 Service Mode in Chapter
problem occurs, replace the relay rear PCB
ASSY.
Check the sensor performance following
the procedure in "Factory Inspection Mode"
in 1.3 Service Mode in Chapter
problem occurs, replace the High-Voltage
PS PCB ASSY.
Replace the main PCB ASSY.
Remedy
Re-assemble the PE actuator MP.
Check the harness connection of the MP
PE sensor ASSY, and reconnect it.
Check the harness connection of the high-
voltage PS PCB ASSY, and reconnect it.
Replace the MP PE sensor PCB ASSY.
Replace the high-voltage PS PCB ASSY.
Replace the main PCB ASSY.
