Settings in the Scanner Window

Image

Resolution
Choose the scanning resolution from the Resolution pop-up menu. Higher
resolutions take more memory and transfer time, but can achieve a finer scanned
image. (Each model has different resolutions. See Specification.)
Color Type
Black & White—Set the image Type to Black&White for text or line art. For
photographic images, set the image type to Gray (Error diffusion) or True Gray.
Gray (Error Diffusion)—is used for documents that contain photographic
images or graphics. (Error Diffusion is a method for creating simulated gray
images by placing black dots in a specific matrix instead of true gray dots.)
True Gray—also is used for documents containing photographic images or
graphics. This mode is more exact because it uses up to 256 shades of gray. It
requires the most memory and longest transfer time.
Colors—Choose either 256 Color, which scans up to 256 colors, 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 approximately three
times larger than a file created with 256 Color.
