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
Use for photographic images or graphics. This mode is more exact because it uses up to 256 shades of
gray.
 256 Color
Uses up to 256 colors to scan the image.
 24bit Color
Uses up to 16.8 million colors to scan the image.
Although using 24bit Color creates an image with the most accurate color, the image file will be about
three times larger than a file created with 256 Color. It requires the most memory and has the longest
transfer time.
Reduce Noise
2
You can improve and enhance the quality of your scanned images with this selection. The Reduce Noise
setting is available when using 24bit Color and scan resolutions of 300
× 300 dpi, 400 × 400 dpi or
600 × 600 dpi.
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.
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.
Note
The Brightness setting is only available when Black & White, Gray (Error Diffusion) or True Gray is
chosen.
