Resolution

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.
Scan Type
3
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 a grey appearance.)
True Grey
Use for photographic images or graphics. This mode is more exact due to using up to 256 shades of grey.
Brightness
3
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 slider to the right or left to lighten or darken the image. You
can also enter a value in the box to set the level.
If the scanned image is too light, set a lower
Brightness
level and scan the document again. If the image is
too dark, set a higher
Brightness
level and scan the document again.
Contrast
3
You can increase or decrease the
Contrast
level by moving the slider to the left or right. An increase
emphasizes dark and light areas of the image, while a decrease reveals more detail in grey areas. You can
also enter a value in the box to set the
Contrast
.
