thank you for your answer Olaf, I installed both iscan and iscan-plugin-gt-9400, they both used to work under ubuntu-12 $ apt-cache show iscan | grep -E '(Status|Package|Version)' Package: iscan Status: install ok installed Version: 2.10.0-2 $ apt-cache show iscan-plugin-gt-9400 | grep -E '(Status|Package|Version)' Package: iscan-plugin-gt-9400 Status: install ok installed Version: 1.0.0-2 > The iscan frontend only works with the epkowa and net backends. iscan used to work with my previous ubuntu but I don't know if 'epkowa' was uncommented in my previous dll.con Furthermore, there is no 'epkowa' in dll.conf if that's what you mean. $ grep epkow /usr/local/etc/sane.d/dll.conf$ > Did you install the non-free plugin that is needed for the Perfection 3170? Yes see above, I'm not sure what you meant by non-free: the plugin is available for download from epson.com > Is it found by the backend? how can I check this ?
