— Unless you have a specific reason
for selecting a higher resolution, we suggest you do
not do so, as the resulting file size may be very large
and take up a lot of your hard disk space. For
example, a 3" x 5" photograph scanned at 2400dpi,
true-color will result in a file over 240MB in size.

Size: — lets you adjust the scan size in the preview
window, enter a width and length in the horizontal and
vertical size boxes, or select a fixed size from the list
box. You can scale the area by dragging the crop box.
The orientation option swaps the width and height
values.
AutoCrop — The AutoCrop function is disabled by
default. Select this option to let the scanner
automatically determine the size of the image being
scanned. When AutoCrop is checked, the scanner
makes two passes. The first pass detects the image
size and the second pass scans the image.
Scan Task — shows the number of previously selected
scan areas (maximum 10 task areas). To remove a
scan task, select the appropriate number of scan areas
and click
Remove .
