Contrast % sets the image contrast by adjusting the difference
between black-and-white, thereby making an image sharper or softer.
In a low contrast setting, the difference between black-and-white is
small, so the image is softer. In a high contrast setting, the difference
between black-and-white is large, so the image is clearer. Select a
contrast value from 1 to 100. The default is 50.
Adjust the contrast setting by dragging the Contrast sliding bar to the
left or right to achieve the desired contrast setting, or you can enter a
value (1 to 100) in the Contrast text box. Scan the document to check
the contrast.
