Scan Type

•
Black & White
Use for text or line art images.
•
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 grey appearance.)
•
True Grey
Use for photographic images or graphics. This mode is more exact because it uses up to 256 shades of grey.
•
8 Bit Colour
Uses up to 256 colours to scan the image.
•
24 Bit Colour
Uses up to 16.8 million colours to scan the image.
Although using 24 Bit Colour creates an image with the most accurate colours reproduction, the image file size will be about three times larger than a file created using the 8 Bit Colour option. It requires the most memory and has the longest transfer time.

Adjusting the Image

•
Brightness
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.
Screen
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 Note
The Brightness setting is only available if you have set Scan Type to Black & White, Grey or True Grey.
•
Contrast
You can increase or decrease the contrast level by moving the slide bar 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.
Note Note
The Contrast setting is only available if you have set Scan Type to Grey or True Grey.
•
Reduce Noise
You can reduce noise of scanned image. When noise appears in scanned image or print image of the scanned image, this setting can reduce the noise.
Note Note
The Reduce noise setting is only available when 24 bit color is chosen and the Resolution is set to 300 × 300 dpi, 400 × 400 dpi or 600 × 600 dpi.
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.
