Scanning an item using the Beginner window options consists of
just a few steps:
1.
Perform a preview scan of the item to be scanned by clicking
on the Preview button. The item is quickly scanned at low-
resolution, and is displayed in the Preview window (on the left
side of the VistaScan Beginner window).
2.
Select what you want to do with the image after it is scanned
using the Scan To icons.
3.
Specify what kind of image you are going to scan, and start the
final scan process using the Click To Scan icons.
Performing the Preview Scan
The Preview feature lets you scan an item at low-resolution so you
can define the specific area to be scanned when you scan at higher
resolution.

under the inverted triangle that appears in the center of the rear
ruler.
2.
Click the Preview button on the right side of the Beginner
window.
