Multifeed Detection tab
A-61789/ISIS January 2016
Multifeed detection aids in document processing by detecting
documents that may go through the feeder overlapped. Multifeed can
happen due to stapled documents, adhesives on documents or
electrostatically charged documents. The Multifeed Detection tab
provides the following options.
Length Detection ⎯ when you enable Length Detection you can
select the maximum length of the document that can be scanned
without a multifeed being detected. Length detection is used when
scanning same-sized documents to check for overlap. For example, if
you are scanning A4 (8.5 x 11-inch) documents in portrait mode, enter a
value of 28.57 cm (11.25 inches) in the Max Length field. The maximum
value is 35.56 cm (13.99 inches).
• Auto Set: automatically sets the maximum length value to 1.27 cm
(.50-inch) greater than the length of the currently selected page size.
Ultrasonic Detection — check this option to set multifeed detection.
• Sensitivity — controls how aggressively the scanner will work to
determine if more than one document is fed into the transport.
Multifeeds are triggered by detecting air gaps between documents.
This allows multifeed detection to be used with job sets containing
documents with mixed thicknesses.
- Low: the least aggressive setting and is less likely to detect
labels, poor quality, thick or wrinkled documents as multifed
documents.
