[sane-devel] USB Scanner Problem

[Peter Kirchgessner]

Hi Jan,

is this scanner really a HP ScanJet 4200c. USB says that it is a ScanJet 
6200c. But that doesn't matter.
After the first (and only) scan has completed, do the following:

export SANE_DEBUG_HP=255

scanimage > hp.ppm 2>hp.lis

and send hp.lis back to me.

Sincerely

Peter
