Adjusting Brightness and Picture Contrast

The brightness of the picture can be controlled by the EXPOSURE control. When the document is dark, has
low cotrast, or is small and dim against a brighter background, use the EXPOSURE control to make the
image clearer.
To adjust brightness, turn the EXPOSURE knob. Turn the knob
toward the HIGH side to brighten the image. Turn the knob toward
the LOW side to darken the image.
Use the DETAIL control to adjust picture quality. Turn the control
toward the HARD side to emphasize the outline of an object. Turn
the control towards the SOFT side for a softer outline.
Brightness may not be adjusted effectively using the EXPOSURE
knob if the image is too dark.
