BASIC SCANNER OPERATIONS
1
Dropout Color
This option excludes selected color (the three primary colors of light i.e. green, red,
blue) from scanned images. For example, if the document contains black text in a red
frame and when the red color is selected, the scanner reads only the text and eliminate
(drop out) the red frame.
If you do not wish to have any colors dropped out select "None".
Reverse
Colors of scanned images are reversed.
Multi feed Detection
Detects Multi feeds (phenomena that two or more sheets are accidentally fed). You can
set conditions for detecting Multi feeds so that the scanner should stop and display
error messages. Multi feeds are scanned by the differences in document lengths or
thicknesses.
