Check & Remedy
Use SIM03-61 to check the operation of the stack tray
lift motor.
Use SIM03-60 to check the tray DC motor encoder
sensor signal.
Use SIM03-60 to check the operation of the tray limit
switch (upper limit, lower limit).
Use SIM03-60 to check each tray position sensor
signal and to check that two or more sensors are not
simultaneously ON.
Replace the control PWB. Check connection of the
connector and harness from the control PWB to the
stack tray lift motor. Check connection of the
connector and harness from the control PWB to the
tray DC motor encoder sensor. Check connection of
the connector and harness from the control PWB to
the tray limit switch (upper limit, lower limit). Check
connection of the connector and harness from the
control PWB to each tray position sensor.
