Confirmation Tasks
Open the front cover, and 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 FSNS connector of main board
(TB3 PCB).
2pin: entry sensor 1
3pin: entry sensor 2
Operate and adjust the sensor lever in order to check the
above signal level.
Check the power supply of 5V of CN connector of front sensor
board (MIP PCB).
1pin: 5V power supply
5pin: 0VL
Confirmation Tasks
