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 and the available colours.

Resolution	Black & White/ Grey (Error Diffusion)	256 Colour	True Grey/24bit Colour
100 x 100 dpi	Yes	Yes	Yes
150 x 150 dpi	Yes	Yes	Yes
200 x 200 dpi	Yes	Yes	Yes
300 x 300 dpi	Yes	Yes	Yes
400 x 400 dpi	Yes	Yes	Yes
600 x 600 dpi	Yes	Yes	Yes
1200 x 1200 dpi	Yes	No	Yes
2400 x 2400 dpi	Yes	No	Yes
4800 x 4800 dpi	Yes	No	Yes
9600 x 9600 dpi	Yes	No	Yes
19200 x 19200 dpi	Yes	No	Yes

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 a grey appearance.)
•	True Grey Use for photographic images or graphics. This mode is more exact because it uses up to 256 shades of grey.
•	256 Colour Uses up to 256 colours to scan the image.
•	24bit Colour Uses up to 16.8 million colours to scan the image. Although using 24bit Colour creates an image with the most accurate colour reproduction, the image file size will be about three times larger than a file created using the 256 Colour option. 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 Colour 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 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, Grey (Error Diffusion) or True Grey.

Contrast

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 grey 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 Grey (Error Diffusion) or True Grey.

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.
