The GT 12000/ES 8000 isn't in the list of the supported devices by SANE,  
so it may not work with the epson-backend. However the external  
epkowa-backend (iscan) may work - it is listed there as 'untested'. To  
make your scanner known to your system, you will have to go to  
'epkowa.conf' and fill in the path to the device simply by uncommenting  
the line with '/dev/scanner' if you have set this link, or to add the  
direct path, i.e. /dev/sg0.

Try the first scan as root. If it doesn't work, chances are high, that the  
GT 12000 isn't supported by the epkowa-backend either.
