Scan Type

Black & White

Use for text or line art.

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 due to using up to 256 shades of grey.

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.

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 grey areas. You can also enter a value in the box to set the Contrast.
