  Yikes. I think I got a severe case of coloredstriperitis.

  Scanned color images show horizontal lines, one pixel high. The
  colors of these lines are clearly off. They seem to lack one or two of
  the RGB components.

  I'm not sure if these are the horizontal stripes that are mentioned in
  the SANE literature, because I only saw one example on the Mustek
  backend homepage which looked quite different from my images.
  Have a look at
  <a href="http://www.xs4all.nl/~ferencj/stripe.gif">
  www.xs4all.nl/~ferencj/stripe.html
  </a>
  for one of my images with this problem.

  I have a Mustek ScanExpress 12000SP (says the cover) with
  firmware 2.02 (says SANE). The scanner is tied to a nameless
  NCR810 SCSI card, no other SCSI devices are involved.

  Slackware 7.1, kernel 2.2.17 drives the linux box, ncr53c7,8xx.o
  drives the card. SANE 1.0.4 with Mustek backend 1.0.4 compiles
  flawlessly - BTW I only compile the backends mustek and v4l to save
  time.

  Changing the SCSI driver (to ncr53c8xx.o or sym53c8xx.o) doesn't
  help. Neither does changing the resolution. Also, altering
  mustek.conf doesn't help. I tried an active terminator on the unused
  scanner port, scanner doesn't work at all.
  I'm running out of options here.

  Incidentally, the setup (SCSI card, -cable, scanner and SANE (don't
  remember which version though)) used to work fine in another linux
  machine.

  Scanner also performs OK with Mustek s/w, but this is on another
  machine, another cable, another card and of course on another OS.

  Sorry to be a bit long, but I thought you'd want this information.

  Please advise.

  thanks for reading this far & cheers

  Ferenc
