White Seed value is set to 200, brighter parts (values from 200-255) of
the image are considered white. In this case light, thin, gray lines
contained in the image may not be scanned correctly. Increasing the
White Seed value ensures that lighter lines are scanned correctly.

Halftoning Method: Halftoning Method options are only available when
Monochrome is selected from the Mode drop down list. The following
options are available here:

Error Diffusion: This is the default value that produces the best copy
quality. Error Diffusion optimizes the scanned original for printing by
applying an error diffusion pattern. This option should not be used when
scanning to file since the error diffusion pattern increases the file size and
makes the files harder to use for raster to vector conversion.

•
Fixed Threshold: When this option is selected, image quality is
controlled using a selected Threshold Value. Then every 8-bit pixel is
compared to this value. If the pixel value is less than the Threshold
selected, the pixel is considered black; if greater than, it is considered
white.

Bi-Tonal: When Bi-Tonal is selected, all lines and marks are scanned in
as solid black for improved visibility. Select this option when scanning
and copying documents with very fine lines like pencil drawings.

Threshold: This option is not available when Grayscale (8Bit) or Color
(24Bit) is selected from the Mode drop down list. The default Threshold value
is 100. Increase or decrease this value as necessary depending on the scanning
configuration selected.

Contrast: Enter a contrast value between 96 and 160 in this text box. Lower
values make the image darker and higher numbers make the image lighter.

Mirror: Select this check box to mirror the scanned image.

Batch scanning: Batch scanning increases scanning speed when scanning
multiple documents of the same width. Batch scanning should only be used
when scanning documents of the same type. When Batch is selected, the first
image loaded from the set is pre-scanned. The resolution, width, height, seed
values, and edge detection set for the first document are applied to all
subsequent images scanned until Batch scanning is disabled.
