<P>Tried it out, problem got worse. Set them both to zero, got floating point errors
<BR>
when scanning. Set them to 1 and got better reults then with the original
<BR>
setting, but still not quite right. I think zero would be better. Also noticed
<BR>
that colors aren't correct. I was scanning sheet of white paper with blue
<BR>
writing. Paper came out white, but the ink looked more like a brownish black.
<BR>
Maybe that is because of the offset. How can I fix the resolution? The scanner
<BR>
runs only have of the length of the page, and scans only about a quarter of the
<BR>
width. I think this is because of the higher resolution of this scanner. It has
<BR>
an optical resolution of 600x1200 dpi.
