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.
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.
256 Colour
Uses up to 256 color to scan the image.
24 bit Colour
Uses up to 16.8 million color to scan the image.
Although using 24 bit Colour creates an image with the most accurate color, the image file will be about
three times larger than a file created with 256 Colour. It requires the most memory and has the longest
transfer time.
Brightness
2
Adjust the setting (-50 to 50) to get the best image. The default value is 0, representing an average.
You can set the Brightness level by dragging the slide bar to the right or left to lighten or darken the image.
You can also enter a value in the box to set the level.
