Click to automatically detect and scan the front or the rear
page of your color document in color image mode. If your
document is in colors, the scanner will automatically scan
the document into a color image. If your document is non-
color, you can choose the output to be either B&W or Gray
from the Non-Color Selection option. This option is useful
when you have a mixture of color and non-color document.
Note: If you choose Front Rear Auto Color Detection, you
can not specify the image mode of your rear page and vice

Sensitivity of Auto Color Detection
If your documents contain primarily B&W text and small
amount of light or pale colors and you do not wish them to
be recognized as color image to save the file size, you can
reduce the sensitivity value by moving the bar to the left to
let these images to be detected as B&W. The value ranges
from 1 to 30. The default is 20.
