■ Black and White—The scanning pixels are all the same size and
are either black or white. Use this setting for letters, memos, pen
and ink drawings, and other black and white material. This
setting produces the smallest file size for scanned items.
■ 256-Level Gray—Scans the image using up to 256 true shades of
gray. Use this setting to scan black and white photographs and
other higher quality black and white images. You can also scan a
color photo with this setting to turn its colors into gray shades.
The file size is about one third the size of a color scan.
