To project white documents much whiter, press the WHITE PAPER
button.
If the button is pressed, the WHITE PAPER indicator lights up.
If the button is pressed again, the indicator turns off and returns to
regular mode.
The effectiveness may vary depending on the document, including how dark it
is.
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.
