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.
