Scan Type 2
Black & White
Use for text or line art images.
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 a gray appearance.)
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 reproduction, the image file size
will be about three times larger than a file created using the 256 Color option. 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 and is
usually suitable for most images.
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 you set Scan Type to Black & White, Gray or True Gray.
Contrast 2
You can increase or decrease the contrast level by moving the slide bar to the right or left. An increase
emphasizes dark and light areas of the image, while a decrease reveals more details in gray areas. You can
also enter a value in the box to set the Contrast.
Note
The Contrast setting is only available when you set Scan Type to Gray or True Gray.
When scanning photographs or other images for use in a word processor or other graphics application, try
different settings for the Resolution, Scan Type, Brightness and Contrast to see which setting best suits
your needs.
