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 one of the following:
 Auto
Automatically detects whether the document uses color and generates a scanned image of it. For
documents that mix color and black and white pages, color pages will be scanned in Color mode,
while black and white pages will be scanned in Black & White mode.
 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
grayscale 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 exact due to using up to 256 shades
of gray.
 24bit Color
Uses up to 16.8 million colors to scan the image. Although using 24bit Color creates an image with
the most accurate color reproduction, it requires the most memory and has the longest transfer time.
NOTE
The Contrast setting is only available when setting Scan Type to Gray (Error Diffusion), True Gray or
24bit Color or Auto.
