Paper size detection

• The size of the paper loaded in the tray 1 section is detected by the combination of ON or
OFF positions of the three paper feed tray 1 multi FD size sensors and the paper feed tray 1
multi CD size sensor.
• Moving the paper guide rotates the size detection gear and the paper feed tray 1 multi
CD size sensor's detector located on the same axis of rotation as the size detection gear.
With the rotation of the paper feed tray 1 multi CD size sensor's detector, a value is
detected and used to calculate the paper width.
