Basic Operation

2.2 BASIC OPERATION
The shift tray allows copies to be sorted into separate piles on one tray.
From the left-right movement of the tray cover [A], the piles of copies are offset into two
positions, slightly overlapping one another.
The half turn sensor [B] detects the actuator [C] of the slip disc. As a result, the machine
can determine if the tray is at the front side or the rear side.](http://img.usermanuals.tech/thumb/64/100811/w64_b230-service-manual-1509630901_d-1147.png "Page 1148
