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 excessively skewed
documents is likely. Overscan reduces the possibility of corner clipping
on skewed images. Overscan can only be used with Fixed or Transport
cropping.
To set Overscan values, select where you want to apply Overscan
values: Top/Bottom, Left/Right; All Sides then select the amount of
inches/mm you want applied. Select a value within the range of 0 to .375
inches. (none) is the default. Combined Overscan and Length values
