Scanning the Image
When you are finished selecting settings on either the easy or advanced screen, and the image you are scanning looks just right in the advanced preview window, you can scan the image by choosing the Scan button.
If you choose Scan from the easy screen, TWAIN automatically selects the entire image and scans it.
If you are scanning from the advanced screen and have not previewed the image or selected a preview area for it, be sure to click the Auto Locate icon before choosing Scan. Otherwise, the entire document table is scanned.
When you close the TWAIN screen, you can further modify your image using the features of your image editing software.
