Kodak i30 / i40 manual Multifeed tab

	Filter Threshold  the value that is used to identify the color which will
	be dropped out. This value is applied to the color area. Color with a
	Red/Green/Blue component more than the entered value is dropped.
	This setting determines how much of the selected color is dropped out.
	A lower value will leave more of the selected color in, while a higher
	value will drop more of the selected color out.
	Background  this value will be substituted in the grayscale (pre-
	thresholded) image for the color being removed. Therefore, this value
	should be higher than the threshold value selected on the Imaging tab
	for this pixel to become the background color. For example, if you are
	scanning a white document with a green form and you have selected a
	bi-tonal threshold value of 127, you should choose an electronic color
	drop-out background value greater than 127 so the substituted pixel will
	be white in the dropped-out image.
The Multifeed tab	Multi-feed Detection aids in document processing by detecting
	documents that may go through the feeder overlapped.

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 is best used when scanning same-sized documents. The maximum value is 14 inches.

Multifeed Stops Scanning  if this option is not selected, the scanner will log the condition but continue to operate. If selected, the scanner will log the condition and stop the feeder (the scanner will be disabled). When an overlap or multi-feed is detected, the scanner stops the feeder, clears the transport of all pages and then the documents can be refed.
