Width — the width of the scanning area.
Length — the length of the scanning area. If Overscan is not selected,
the scanner will not continue capturing beyond the trail edge of the
document. For example, if you setup the scanner for 8 ½” x 11”
portrait-fed documents, and you scan an 8 ½ x 4” document, the
scanner will return an 8 ½ x 4” scanned area.
Center Frame when using fixed cropping, automatically calculates
the X-offset for center-fed feeding based upon document size selected.
This option is not available if you use auto cropping.
Rotate Frame when using fixed cropping, automatically calculates
the offset values based upon feed orientation of the document size
selected (landscape vs. portrait). This option is not available if you use
auto cropping.
Overscan values
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 and/or the left and right 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.
To set Overscan values, select where you want to apply Overscan
values: Top/Bottom, Left/Right; All Sides then select the amount
(inches or mm) you want applied. Select a value within the range of 0
to .375 inches None 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.
Additional paper selections
In addition to cropping and overscan values that can be applied using
the Paper tab, the following options are available:
