SHIFT TRAY SIDE-TO-SIDE SHIFT MECHANISM

[A]
[F]
[G]
In the sort/stack mode, the shift tray [A] moves from side to side to stagger
and separate sets of copies.
The horizontal position of the shift tray is controlled by the shift motor (dc
motor) [B] and the shift cam (helical cam) [C]. After one set of originals is
copied and delivered to the shift tray, the shift motor [B] starts rotating, driving
the shift cam through the timing belt. The pin [D] fixed to the shift tray base
plate [E] is positioned in the groove on the shift cam, creating the side-to-side
movement required to stagger copies.
When the shift cam rotates 180 degrees (when the tray is fully shifted.), the
plate [F] on the shift cam pushes the actuator [G] of the shift tray half-turn
sensor [H] and the shift motor stops. The next set of copies is then delivered.
The motor rotates repeating the same process and moving the tray back to
the previous position.
