JPEG Quality JPEG compression offers a JPEG quality of Draft,
Good, Better, Best, Superior and Sharpen.
• Draft the smallest file size with draft image quality.
• Good a larger file size with good image quality.
• Better a larger file size with better image quality.
• Best a larger file size with the best image quality.
• Superior the largest files size with superior image quality.
• Sharpen this filter increases the edge contrast of the image
without effecting the color component. Use this option when a high
contrast result is desired. For example, if you scan text documents
in color.
Overscan allows you to add a specified value (inches/mm) before
and after the edge of the image. Overscan values can be applied to the
top and bottom of an image. Overscan is used in applications where
automatic feeding of highly skewed documents is likely. Overscan
reduces the possibility of corner clipping on skewed images. Overscan
is used with Fixed Cropping only and Deskew must be disabled.
To set Overscan values, enter a value in the text entry box. The range is
0 to .450 inches. 0 is the default. Combined Overscan and Length
values cannot exceed 30 inches for all resolutions except 400 dpi
bi-tonal, which cannot exceed 26 inches.
Units defines the primary measurement system. Pixels, Inches, and
Centimeters are available. Select the option desired.
Image Control options
The following Image Control options are available:
Border Framing allows you to add a border to the final image. The
width of this border is 16 pixels. This option is only available with Auto
Cropping and only applies to binary images.
Halftone Removal used to enhance images containing dot matrix
text and/or images with shaded or colored backgrounds using halftone
screens. This filter effectively eliminates noise caused by the halftone
screen. This option is only applied to binary images.
