Media size detection control

• The media size switch detects the length size (FD) of the media.
1. The size detection board turns as the trailing edge guide plate is moved.
2. When the tray is slid into the main body, the size detection board pushes the actua-
tor of the media size switch installed to the main body frame, thus turning ON the
switch.
3. The combination of ON/OFF positions of the sub-switches of the media size switch
determines the specific media size that can be either one of the seven different
sizes.
4. If the tray is not slid into position, all of the sub-switches are OFF and the message
"OUTPUT FULL REMOVE PAPER (MAIN TRAY)" appears.
