  Hello Lawrence.

  Did that - in fact those are the programs that I've been using all along.
  There seems to be a difference between the two models. I've got the
  firmware uploadable one, and have to upload it each time electricity
  fails... Now I've put the upload in the rc.local file. All this works fine,
  as does grayscale and line art scanning. The problem is color. I'm game
  to try anything - I believe I tested most combinations possible, and some
  I invented too ;-)

  Thanks for the suggestion!

  John (ON6JC and LW3HAZ)
