SHIFT TRAY

The shift tray motor [A] moves the tray up and down.

The upper limit switch [B] detects when the tray moves up too far, and cuts power to the

shift tray motor.

The shift tray position sensor [C] checks when the tray (or the top of the stack) is at the

correct height to receive paper.

Shift Mode: This is checked every 5 sheets

Staple Mode: This is checked every stack

The lower limit sensor [D] detects when the tray is full. At this point, the tray cannot move

down any more.
