Settings in the Scanner window
Image
Resolution
From the Resolution pop-up menu choose the scanning resolution. Higher resolutions use more memory and transfer time, but produce a finer scanned image.
Color Type
Black & White—Set the image Type to Black and 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 with photographic images or graphics. (Error Diffusion is a method for creating simulated gray images by placing black dots instead of the true gray dots in a specific matrix instead of true gray dots.)
True Gray—is used for documents with photographic images or graphics. This mode is more exact because it uses up to 256 shades of gray. It requires the most memory and takes the longest transfer time.
Colors—Choose either 256 Color, which scans up to 256 colors 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 three times larger than a file created with 256 Color.
