Choose the output image type from Photo, Web or Text. Resolution and Scan Type will be altered for each
default setting.
The default settings are listed in the table below:
Resolution 2
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 colors.
Scan Type 2
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 gray images
without using true gray dots. Black dots are put in a specific pattern to give the appearance of gray.)
True Gray

gray.
