First off, I've totally rid myself of Windows :^) so I can't test
this scanner with Win software. I was hoping someone out there
would recognize my problem as a common one that I'm too dense to
figure out.
I installed SANE 1.0.1 on Red Hat 5.2 along with the sane-client
package, both RH version 1.0.1-2. Fired up my scanner and did a
number of scans of a test copy, a copier-made sign done on blue
paper.
When I view the output image all I get is a totally white image.
No hint of color or of the black printing on the sign. SANE seems
to drive the scanner OK (although it did get confused when I tried
to run it with xscanimage and also when I tried to do an xscanimage
preview) and without SCSI-type errors.
I ran scanimage with the verbose option and it reports ranges for red
of like 175-255, green of like 165-255, and blue of like 120-255 IIRC.
It *seems* to know there are colors out there to scan, but the image
produced is just plain white (checked with both xv and gimp). It
passes all tests with the -T option just fine.
I just downloaded the latest firmware from the umax.de site and I'll check
to see if I need to burn an updated firmware chip. I'm not sure what
version of firmware it's using now.
Has anybody seen similar problems before? Do I need to tune some of the
brightness, color, etc. parameters? I didn't find reference to this
problem in the FAQ. TIA!
