Paper-ejecting route across
paper eject part.
Check the paper-ejecting
sensor lever.
Check the condition of sensor
signal detection.
Check the output level of
EXIT sensor.
Check the power supply of

Confirmation Tasks
Check whether the paper jam occurred during the route.
Check whether there is something abnormal about the form of
sensor lever and its movement.
By using the switch scanning test function of the maintenance
utility, check whether the sensor signal has been normally
detected.
Check the following signals of RSNS connector of main board
(BLA PCB).
9pin: EXIT sensor
Operate and adjust the sensor lever in order to check the above
signal level.
Check the power supply of 5V of CN2 connector of rear sensor
relay board (ZAK PCB).
1pin: 5V power supply
3pin: 0VL
Check whether FFC has been inserted into RELAY connector of
main board (BLA PCB) and CN1 connector of rear sensor relay
board (ZAK PCB) normally.
Check whether the cable between color difference sensor board
(ZAK PCB) and EXIT sensor has been connected normally.
Check whether wire gnawing, peel-off or defective cable
assembly exists.
Action at NG
Remove the jammed
paper.
Replace the sensor
lever with a new one.
