IMAGE TYPE
From the Image Type drop-down list, select the appropriate image type
for the item(s) you’re scanning:
Black and White—scans in 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.
Halftone—scans the image so it appears to consist of gray tones.
A pop-up menu appears so you can choose one of the halftone
options. Notice that the preview image changes as you select each
option so you can see which one is best for scanning. Halftones
produce simulated gray tones by using black and white pixels of
different sizes and is often used to produce newspaper and
magazine images. Use this setting for lower resolution black and
white images. The halftone settings also produce small file sizes.
