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.
Reverse
Colors of scanned images are reversed.
Background
Specifies the Background color. Enabled only for the scanners equipped with Back-
ground color switching mechanisms.
Power saving
This option specifies the waiting time before the scanner switches to the Power save
mode.
Double Feed Detection
Detects Double-feeds (phenomena that two or more sheets are accidentally fed). You
can set conditions for detecting Double-feeds so that the scanner should stop and dis-
play error messages. Double feeds are scanned by the differences in document lengths
or thicknesses.
