[sane-devel] HP Scanjet G4010

[Brian Shaver]

Stef,
You are correct, changing the following line now produces results:

  /* set up clock once for all */
  if (1) /*if (strcmp (dev->model->name, "hewlett-packard-scanjet-g4050") ==
0) */

Trying Gray, Color and Lineart modes. The result for Gray was pretty good.
With the Color mode I'm seeing some ghosted image effects. The Lineart mode
produced an image which was nearly all black.

Thanks,
Brian ..
