Right Tray Fence Movement Mechanism

• The tandem tray is equipped with two fence solenoids, one for the front side fence and one for the
rear fence.
• When paper runs out in the right tray, the front and rear fence solenoids turn on, open the front and
rear fence, and then remain on until the fence open sensor goes on.
• When the paper stack is pushed into the right tray from the left tray, the rear fence return sensor
detects the stack now in the right tray, and then switches the fence solenoids off which closes the
front side fence and rear side fence.
