Color Type
Black & White—Set the image Type to Black and White for
text or line art. For photog raphic images, set the image type
to Gray (Error diffusion) or True Gray.
Gray (Error Diffusion)—is used for documents that have
photographic images o r graphics. (Error Di ffusion is a method
for creating simulated gray images without using true gr ay
dots. Black dots are placed in a specific pattern to give the
appearance of gray.)
True Gray—is used for documents with phot ographic images
or graphics. This mode is more exact because it uses up to
256 shades of gray. It requi res the most memory and takes
the longest transfer time.
Colors (not available for MFC-722 0 and MFC-7225N)—Choose either 8 -bit Color, which scans up to 8-bit
Color or 24-bit color which scans up to 16.8 million colors. Although using 24-bit color creates an image with
the most accurate colors , the image file will be about th ree times larger than a file crea ted with 8-bit Color.
