When you preview an item to scan, the selection rectangle around the
image indicates the scan area. However, you may want to select only a
certain area of an item to scan. Selecting an appropriate scan area can
result in a faster scan and a smaller file size.
To select the area you want to scan:
1. Click the Preview button. An image of the scanned item appears in
the Preview area. A selection rectangle shows the current scan area.
2. (optional) In the Scan Configuration settings, select the units of
measure you want to use for the scan area. You can select either
inches, centimeters, or pixels.
3. To change the dimensions of the rectangle, click the rectangle, and
then drag the borders of the rectangle to resize it. This effectively
allows you to crop the item. The dimensions of the selected area
appear in the Scan Configuration settings.
You can also type length and width dimensions directly into the
boxes that show the dimensions of the selection area. Use this
process to produce a precise scan area size.
4. To position the rectangle over the area you want to scan, click and
hold the left mouse button and drag to the location desired.
5. Click the Scan button to scan the image.
Note: For more detailed information on advanced settings, click the
Help button on the Scan Manager.
