Color mode
The color mode specifies color reading or monochrome
reading. In color reading, you can choose either page sequence
reading or line sequence reading. In monochrome reading a
dropout color can be specified (green, red, or blue).
Color page sequence reading
The scanner scans the document three times (one each for
green, red, and blue), and produces three pages of image
data that combine to give full color image data. Since the
image data can be divided into three sets, a computer with
limited memory or processing speed can handle it more
easily.
Color line sequence reading
The scanner scans the document with one pass of the
carriage, reading green, red, and blue for every line. This
yields more accurate color separation. Because the color for
each pixel can be determined as soon as it is read, the color
correction function can be used.
Monochrome reading
The scanner scans the document with one pass and reads
the image in monochrome (black and white). In standard
monochrome, the scanner the document with
the green, red, and blue lights all at once so that minimum
dropout color results.
Dropout colors (monochrome reading only)
The dropout color is the color you tell the scanner not to
read. You can choose a dropout color from green, red or
blue. Use a dropout color when you do not want to read
one of these colors-for example, when scanning an image
on a colored background.
The default color mode is standard monochrome.
