Bypass Feed Tray Automatic Lifting System
The Bypass Tray Bottom Plate has an automatic lifting system.
When the main motor rotates in reverse, a one-way clutch transfers the drive to the bottom plate lifting system of the
bypass tray. Then, a cam (on the left as you face the machine) starts rotating to lift the bottom plate up and down. The
bottom plate position sensor detects up/down movement of the bottom plate by detecting a sensor actuator on the left
side of the cam.
