Paper size detection

• When the trailing edge stop of the drawer is moved, the circular plate located on the bot-
tom of the drawer turns, allowing the four FD paper size sensors on the paper size board.
• moving the edge guide activates or deactivates the two CD paper size sensors through
the cutout in the lever.
• The combination of the four FD paper size sensors and two CD paper size sensors that
are either activated or deactivated determines the size of the paper loaded in the drawer.
• The tray device detection sensor detects that the drawer is slid into position as it is slid in.
