B. Bin paper sensor sensitivity adjustment
This adjustment must be performed when replacing the following
parts:
•
Sorter controller PWB
•
Bin paper sensor (S1, S2)
Note: To perform this adjustment, the bin unit must be assembled
completely in advance. If the adjustment is performed without
assembling the cover, etc., the sensor will receive external
lights, resulting in an error in adjustment.

•
Guide bar home position sensor (PI3)
•
Guide bar oscillation motor (M3)
<Operating procedure>
1) Prepare one sheet of A4 or letter paper for copying.
2) Remove all the paper from the bins.
3) Remove the right cover, and set the DIP switch (SW1) on the
sorter controller PWB as shown below. (Note that the setup con-
tent differs depending on the copy paper size.)
