Kodak i800 Series manual Multifeed tab

The Multifeed tab	Multi-feed Detection aids in document processing by detecting
	documents that may go through the feeder overlapped. Multi-feeds can
	happen due to stapled documents, adhesives on documents, or
	electrostatically charged documents. 3D Multi-feed Detection combines
	ultrasonics (amplitude and phase) with physical length detection to
	virtually eliminate the chance of loosing data due to multi-feeds.
	The Ultrasonic Sensor is located in the center of the transport (behind
	the feeder module). In order for multi-feed documents to be detected
	correctly, they must pass under this sensor.

Length Detection  choose the minimum length of the document that can be scanned with a multi-feed being detected. The Display window will show the size of the document as you change the value. You can select to display this amount in Inches, Centimeters, Picas, Points, 20th of Points or Pixels. A value of 0 indicates no length detection. Length detection can be used when scanning same-size documents. The maximum value is 30.5 inches.
