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 colours.
Scan Type 2
Black & White
Use for text or line art.
Grey (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 the appearance of grey.)
True Grey
Use for photographic images or graphics. This mode is more exact because it uses up to 256 shades of
grey.
