A good image has characters that are not too dark or touching and are not too light
or broken. It also has characters that are distinct from the background. The
background in a good image is light and not "fuzzy" or "dotty."
To process a document with pages that vary in character image quality (too
dark/touching, too light/broken) or in background (color or "noise"):
1. Use the brightness level control in your scanner software to manually select
a brightness level.
2. Click Get Page to get the page, or choose Get Page from the Process menu.
3. Zoom in on the page to see if it's a good image.
If the image looks good, skip to step 9.
4. If you're not sure if it's a good image, use the Locate and Recognize on the
page, then check the results.
If there are many suspect and illegible characters in the recognized text, you
may be able to improve recognition by experimenting with a different
brightness setting.
