  I'm running Sane 1.0.4 on Linux - Mandrake 7.2 (kernel 2.2.17), with a
  Tekram DC-390U SCSI adapter (NCR 53c875e chipset).
  I have a Umax 1200S and an HP C5100A Rev 032. Both are recognised by the
  kernel, and the Umax works fine.
  The PhotoSmart, however: trying to scan a slide, everything seems to be
  working fine EXCEPT: the image I get from xscanimage is just solid
  black. All other functions of xscanimage work - when I ask for a preview
  image, the slide is taken in, it whirs appropriately, and for the scan
  itself it makes all the right noises and then ejects the slide.
  I tried using scanimage with and without options: same all black image.
  What's going on? Do I need to calibrate the 5100A? There is a
  calibration card that came with the scanner but none of the
  documentation I've found on the HP backend says anything about
  calibration.
  I tried scanning a print: very dark, faint blue image could be observed.
  However scanning a strip of negatives looks much better.
  There are no errors in /var/log/messages. Here's the SCSI device list:
  $ cat /proc/scsi/scsi
