2. Detecting by the Bin Inside Paper Sensor
Perform this check when following parts are replaced.
• Paper sensor in bin unit (PS1, PS2)
Procedure
1) Remove all the paper from the bin unit.
2) Detach the rear cover and set the dip switch (SW3) on the sorter controller PCB as shown
below.
* The No.6 switch is used for switching the communication system with the copier and
should not be moved.
3) Put copy paper in the bin, and check the condition of the Manual Staple key:
It should turn on to indicate the presence of paper, and
It should remain off to indicate the absence of paper.
4) If the Manual Staple key does not operate as expected, check to see if the bin inside paper
sensor (light-emitting side, light-receiving side) is mounted correctly, and check the activation
of the sensor once again.
5) Thereafter, shift the bits of the DIP switch (SW3) on the sorter controller PCB to their original
positions.
