Device - Multifeed tab Multifeed detection aids in document processing by detecting
documents that may go through the feeder overlapped. Multifeeds can
happen due to stapled documents, adhesives on documents, or
electrostatically charged documents.
Ultrasonic Detection
Sensitivity — controls how aggressively the scanner will work to
determine if more than one document is fed into the scanner. Multi-
feeds are triggered by detecting air gaps between documents. This
allows multifeed detection to be used with job sets containing
documents with mixed thicknesses.
• (none)
• Low: least aggressive setting and is less likely to detect labels, poor
quality, thick or wrinkled documents as multi-fed documents.
• Medium: use if your job set has varying document thicknesses 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: the most aggressive setting. This is a good setting to use if all
documents have a thickness no greater than 75.2 g/m

NOTE: Regardless of the setting, “sticky” notes may still be detected
as multi-fed documents.
