Hello Sascha, I'm delighted that you have a MX710 series, which we can now debug! > scanimage: open of device pixma:04A9175D_20C2C2 failed: Operation not > supported > scanimage (sane-backends) 1.0.23; backend version 1.0.23 > device `pixma:04A9175D_20C2C2' is a CANON Canon PIXMA MX710 Series > multi-function peripheral > I used the actual pixma backend. > > Is there any chance to fix the problem. How can I help? Could you read "man sane-pixma" and use the debug variable to get more output? You'll need to run from the command line: export SANE_DEBUG_PIXMA 3 xsane (or scanimage) If there is a bug in the initialization, then maybe we will need Windows USB sniff results also, but as a first step, we should be able to see if something is clearly wrong or not.
