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.

not specify the image mode of your rear page and vice versas.

4.3.2 Other Image Options
Binarization This is the process of converting a
grayscale or color image to a bi-tonal
image. There are several different
methods of performing this conversion.
Options: Dynamic Threshold, Fixed
Processing, Halftone 1~5, Error
Diffusion.
Dynamic Threshold: Selecting
Dynamic Threshold allows the scanner
to dynamically evaluate each document
to determine the optimal threshold value
to produce the highest quality image.
This is used to scan mixed document
containing faint text, shaded background,
or color background with a single setting.
If Dynamic Threshold is selected,
Threshold, Brightness, and Contrast are
not available.
Sensitivity of Dynamic Threshold
Occasionally your scanned image may
contain small dots or speckles. To remove
these spots, increase the sensitivity value
by moving the bar to the right. The value
ranges from 1 to 30. The default is 20.

Fixed Processing: Used for black-and-
white and other high contrast documents. A
single level is set to determine the black-
and-white transition. The threshold is
programmable over the entire density
range. Fixed Processing sets Contrast to
0. If Fixed Processing is selected,
Contrast is not available.
Halftone: In addition to the black and
white display, Halftone can present a
somehow gray shade of image by using
different size of dots. Halftone image looks
like the picture we have seen in the
newspaper. Options include Halftone 1,
Halftone 2, Halftone 3, Halftone 4,
Halftone 5.
Error Diffusion: Error Diffusion is a type
of Halftone. Error Diffusion gives good
image texture and makes text in images
more readable than Halftone.

Threshold Used to convert a grayscale image to a
bi-tonal image. The value ranges from 0 to
255. A low threshold value produces a
lighter image, and can be used to subdue
backgrounds and subtle, unneeded
information. A high threshold value produces
a darker image, and can be used to help pick
up faint images.
Adjust the threshold setting by dragging the
Threshold sliding bar to the left or right to
achieve the desired threshold setting.
