Using the sensor for measuring paper thickness, the thickness of a cover fed at test feed is read
as the reference data, and is compared with the data of the cover fed at the subsequent feed.
When the difference between those data exceeds the double feed detection level (%) you
specified, the machine determines that a double-feed has occurred.
Setting range: 5 to 100 (standard value: 50)
