The side fences [A] of the right tray are normally closed. They open only
when paper in the left tray is transported to the right tray.
The side fences are driven by the side fence drive motor [B] (stepping motor).
When the paper loaded in the left tray is transported to the right tray, the side
fence drive motor turns counterclockwise to open the side fences until the
side fence positioning sensor [C] is activated.
When the rear fence [D] in the left tray pushes paper into the right tray, the
side fence drive motor turns clockwise to close the side fences.
