Scanning
 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
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
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.
NOTE
The Brightness setting is not available when 256 Color is chosen.
Contrast
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 gray areas. You can
also enter a value in the box to set the Contrast.
NOTE
The Contrast setting is only available when Gray (Error Diffusion), True Gray or 24bit Color is chosen.
When scanning photographs or other images for use in a word processor or other graphics application, try
different settings for the contrast and resolution to see which setting best suits your needs.

 A4 210 x 297 mm (8.3 x 11.7 in)
 JIS B5 182 x 257 mm (7.2 x 10.1 in)
