(5-1-1) Check of state of running route
Paper running route in front
unit
Check to see if there is paper jammed on the running
route.
Remove the jammed
paper.
(5-1-2) Check of state of mechanical parts
Check sensor levers of WR
sensor
Confirm that there is no abnormality in the shape of the
sensor lever and in the operation.
Replace the sensor
lever with a normal
one.
(5-1-3) Check of electrical parts
Check the state of sensor
signal detection.
Use the SWITCH SCAN function of the self-diagnostic
mode to check to see if the sensor signal is detected
normally.
Replace the PU PCB
(PRF PCB), front
sensor PCB (RSF
PCB) or connection
cord.
Check the output level of
the WR sensor.
Check the following signal through the FSNS connector
of the PU PCB (PRF PCB).
Pin 2: WR sensor
Confirm that the above signal level varies as the sensor
lever is actuated.
Replace the front
sensor PCB (RSF
PCB).
Check the power supply of
the front sensor PCB (RSF
PCB).
Check 5V power with CN connector of a front sensor
board (RSF PCB).
