Paper size width detection is performed by the bypass width sensor (rotary switch).
The bypass width sensor contains a plate which rotates together with the side fences of the bypass feed table.
Paper portrait/landscape is determined by the length sensor.
Two feelers [A] for the bypass length sensor [B] are added to the rear of the tray to prevent false detection of paper length caused by floating at the trailing edge of the paper when long paper is set without pulling out the bypass tray extension.
