Double feed detection by Ultrasonic
The scanner uses an ultrasonic sensor to detect when two
or more documents are fed together, and stops feeding
when a double feed is detected.
IMPORTANT
• This method is effective when documents overlap by 1.97"
(50 mm) or more. It does not function if only a slight portion of
the document is overlapping.
• When [Scanning Side] is set to [Folio], [Double feed detection
by Ultrasonic] is grayed out and cannot be selected.
Double feed detection by length
The scanner detects by document length when two or more
documents are fed together, and stops feeding when a
double feed is detected.
