You can change the scanning resolution from the
Resolution
drop-down list. Higher resolutions take more
memory and transfer time, but produce a finer scanned image. The following table shows the resolutions you
can choose and the available colors.
Scan Type
9
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.
256 Color
Uses up to 256 colors to scan the image.
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, the image file size
will be about three times larger than a file created using the
256 Color
option. It requires the most memory
and has the longest transfer time.
