Thank you very much. Confirmed working now here as well :)

Hmm, I'm not sure. The list only offered up to 1200 dpi, but it was editable. 
So I tried defining 2400 dpi and from what I can see it worked. At least gimp 
reports the scanned image with 2400 dpi. I did the same for 4800 dpi as well, 
don't know if it is useful or not.

I tried to get as small as possible scans, maybe it ended up too small. If so 
tell me and I'll run it again. I uploaded the logs to my server, they are 
available here: http://www.liwjatan.at/files/logs/

Hope that helps! :)

Grs,
Heinz
