PreScanning an Image
PreScanning allows you to scan an image quickly at a low resolution. A thumbnail version will
appear in the Scanning Area. This is only a preview of the image, so you can see how it will look.
The PreScan button is used to preview an image for cropping any unwanted portions from the
image. When you are satisfied with the preview, click Start to scan the image.
