The side fences [A] of the right tray are normally closed. They open only when the
stack of paper in the left tray is being moved across to the right tray.
The side fences are driven by the side fence drive motor [B] (a stepper motor).
When the paper stack in the left tray is being moved 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.
After the rear fence [D] in the left tray has pushed the stack into the right tray, the
side fence drive motor turns clockwise to close the side fences, until the side fence
close sensor [E] is actuated. Then, a message is displayed advising the user to
load some paper into the left side of the tandem tray.
