Multifeed tab Multifeed detection aids in document processing by detecting
documents that may go through the feeder overlapped.
Sensitivity — controls how aggressively the scanner will work to
determine if more than one document is fed into the transport. Multi-
feeds are triggered by detecting air gaps between documents. This
allows multi-feed detection to be used with job sets containing
documents with mixed thicknesses. You may set the Multi-Feed
Detection to High, Medium or Low sensitivity. If you select None, no
multifeed detection will occur.
• Low: least aggressive setting and is less likely to detect labels, poor
quality, thick or wrinkled documents as multi-fed documents.
• Medium: use Medium sensitivity if your application has varying
document thickness or labels attached to the document. Depending
on the label material, most documents with labels should not be
detected as a multi-fed document.
• High: most aggressive setting. This is a good setting to use if all
documents are similar in thickness to 20-lb. Bond paper.
Length Detection — choose the minimum length of the document that
can be scanned with a multi-feed being detected. A value of 0 indicates
no length detection. Length detection can be used when scanning
same-size documents. The maximum value is 33.5 inches.
