• 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.

1) Remove all the paper in the bins.

2) Remove the right cover, and set the DIP switch on the sorter controller PWB as shown below.

1) Bin paper sensor sensitivity adjustment

1) Guide bar motor oscillation range adjustment

1) Stapler oscillation motor oscillation range adjustment (Staple position adjustment)

5) When the manual staple key blinks, turn off and on the copier power switch, check the status of the bin paper sensor (on the light emitting side and the light receiving side) corresponding to the error code, and perform the adjustment from procedure 1) again.

6) After completion of the adjustment, return the DIP switch on the sorter controller PWB to the original state.

C. Guide bar oscillation range adjustment

The dummy roller lower is of eccentric shape so that you can adjust the height of the bin roller this is so you can adjust the height at which the bin roller and the lead cam tip t ouch. When the bin roller is replaced or reassembled, check the standard dimensions and change and adjust the installing angle of the dummy roller lower if necessary.

1) Adjustment procedure Stand up the bin unit straight. Measure the distance between the

upper dummy roller (1) and the bin roller (2). If the distance is too large, rotate the lower dummy roller (3) counterclockwise. If the distance is too small, turn it clockwise. Turn and adjust so that the distance is about 97.8mm.
