Resolution
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.
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.
