Document width is detected by the Document width sensor 1/2/3 (SR13/SR14/SR15) which performs by light prevention plate
connected with the Slide guide adjustment.
Document sizes are determined by combination of ON/OFF states of these sensors.
The Document length sensor 1 (SR7) is a Reflection Sensor which is available to detect the length of a document in case that
the curled paper is placed on the document pickup tray.
