Level—for quickly adjusting color and gray images. These buttons do

Select this option when scanning a picture from a newspaper or
magazine article, sales catalog, or other source that contains images with
patterns or dots. Scans of patterns or dots sometimes have a distorted or
wavy appearance. The scanner scans the item to compensate for the
patterns and dots, and produces a clearer image. The scanning may slow
down a bit when this option is selected. You don't need to select this
option when scanning photographs.
