Paper Size Detection
The paper size detection for Trays 2 and 3 is determined by three paper Size
Switches in each paper tray slot. The switch condition is set by moving the
paper end guide in the tray. This in turn sets the plastic “fingers” on the side of
the paper tray to a specific position that activates the correct switch
combination for the selected paper size.
