Scanning Scan Type 10 „ 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 the gray appearance.) „ True Gray Use for photographic images or graphics. This mode is more exact because it uses up to 256 shades of gray. „ 8 Bit Color Uses up to 256 colors to scan the image. „ 24 Bit Color Uses up to 16.8 million colors to scan the image. Although using 24 Bit Color creates an image with the most accurate color reproduction, the image file size will be about three times larger than a file created using the 8 Bit Color option. It requires the most memory and has the longest transfer time. 10 179
