Scan (Image Type) Resolution Scan Type Photo Use for scanning photo images. 300 x 300 dpi 24bit Color Web Use for attaching the scanned image to web pages. 100 x 100 dpi 24bit Color Text Use for scanning text documents. 200 x 200 dpi Black & White 2. Resolution Select a scanning resolution from the Resolution drop-down list. Higher resolutions take more memory and transfer time, but produce a finer scanned image. 3. Scan Type Select from a range of scan color depths. • Black & White Use for text or line art images. • Gray (Error Diffusion) Use for photographic images or graphics. (Error Diffusion is a method for creating simulated gray images without using true gray dots. Black dots are put in a specific pattern to give a gray appearance.) • True Gray Use for photographic images or graphics. This mode is more accurate because it uses up to 256 shades of gray. 169
