Kodak A-61580 manual Ultrasonic detection

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. Multifeeds 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: most aggressive setting. This is a good setting to use if all documents are similar in thickness no greater than 20-lb. bond paper.

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