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.
