Basic Operation

Shift Movement
●
•
The machine moves the tray to the front and the rear to sort stacks (offset). The tray is
driven by a DC motor, and the rotation of the motor is converted into liner movement
by means of a rack and pinion gear mechanism. The location of the tray (front, rear) is
monitored by the HP sensor mounted to the front and the rear.

● Placement of Paper
•
The machine's tray is held up by the work of a coil spring. When paper is placed, the tray
moves down under the weight of the paper. The height of the stack in the tray is monitored
by the tray full sensor (reflection type photo sensor), and the shift tray driver PCB sends the
tray full signal to the host machine when the top of the stack reaches a specific height.
