and transfer time, but produce a finer scanned image. The following list shows the resolution you can choose.

Colour Type
Black & White
— Set the image Type to
Black and White
for
text or line art. For photographic images, set the image type
to Gray (Error diffusion) or True Gray.
Gray (Error Diffusion)
— is used for documents that have
photographic images or graphics. (Error Diffusion is a method
for creating simulated gray images without using true gray
dots. Black dots are placed in a specific pattern to give the
appearance of gray.)
True Gray
— is used for documents with photographic
images or graphics. This mode is more exact because it uses
up to 256 shades of gray.
Colours
— Choose either 8-bit Colour, which scans up to 256
colours or 24-bit colour which scans up to 16.8 million colours. Although using 24-bit colour creates an image
with the most accurate colours, the image file will be about three times larger than a file created with 8-bit
Colour. It requires the most memory and takes the longest transfer time.
