Here is another description of a problem with the Coolscan backend
from a Debian Linux user.

Package: sane
Version: 0.74




I tried sane versions 0.72 (from Hamm) and sane 0.74.
Compared with the W95 software shipped with the Nikon Coolscan
LS-20 the scans are significantly unsharp.


This may be caused by a broken autofocus routine.  A hint for
this is the terribly noise which the scanner produces before
doing the scan.


Kind regards


            Andreas.
