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.
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 if you have set Scan Type to Black & White,
Gray (Error Diffusion) or True Gray.
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 gray areas. You
can also enter a value in the box to set the Contrast.
Note
The Contrast setting is only available if you have set Scan Type to Gray (Error Diffusion) or True Gray.
