I have successfully compiled and installed sane-0.67 on a Linux system<br>
with a UMAX UC630 scanner attached using a SCSI host adapter.<br>
<p>
Now I am trying to get useful scans from it.<br>
<p>
This is my first experience with a scanner of any sort (using any OS), so<br>
please excuse my novice questions.<br>
<p>
I have experimented with scanimage and xscanimage, but the results are<br>
always the same. The color of the image is very poor, and I don't know<br>
what adjustments to make to improve it. I have fiddled with the "white<br>
level" and "black level" sliders, but to no avail. I have also made<br>
adjustments using the gamma tables in xscanimage, but the previews always<br>
look the same.<br>
<p>
I am guessing that a gamma table that works for on UC630 would work for<br>
all of them. Does anyone have one that they can provide?<br>
<p>
If not, could someone tell me how to go about correcting the color<br>
problems? I don't know where to begin.<br>
<p>
Thanks in advance for your help.<br>
