Resolution 3
You can choose a 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 colours.
Scan Type 3
 Black & White
Use for text or line art.
 Gray (Error Diffusion)
Use for photographic images or graphics. (Error Diffusion is a method for creating simulated grey images
without using true grey dots. Black dots are put in a specific pattern to give a grey appearance.)
 True Gray
Use for photographic images or graphics. This mode is more exact due to using up to 256 shades of grey.
 256 Color
Uses up to 256 colours to scan the image.
 24bit Color
Uses up to 16.8 million colours to scan the image.
Although using 24bit Color creates an image with the most accurate colour, the image file will be about
three times larger than a file created with 256 Color. It requires the most memory and has the longest
transfer time.
