Changing the background
bars
There are two background bars located inside of the scanner; an upper
background bar and a lower background bar. Each bar has a white side
and a black side. These bars can be easily changed. The background
color is important because is may affect the cropping quality of the
scanned image.
Most of the time, you will scan your documents using the black
background. The black background can
improve imaging of documents
with very light contrast data and increase color uniformity.
You should use the white background if you are scanning translucent
documents. The white background will reduce black background bleed-
through, which produces whiter images.
The background color set up in your scanning application, must match
the color of the background bars.
To change the background bars:
1. Turn the scanner off and open the exit door.
2. Locate the lower background bar, place your finger on the right end
of the bar and push it to the left. Rotate the background bar until the
desired color is showing. Release the pressure on the background
bar and verify it is locked in place.
3. Locate the upper background bar, place your finger on the left end
and push it to the right. Rotate the background bar until the desired
color is showing. Release the pressure on the background bar and
verify it is locked in place.
Both background bars should be the same color.
4. Gently close the exit door and turn the scanner on.
