As far as I understand, you are using your scanner with Ethernet or Wifi connection. And it tries to communicate with an IP address, but in message, we can read both:
Failed to open device 'pixma:MX350_192.167.1.88': Invalid argument. and scanimage: open of device pixma:MX350_192.168.1.88 failed: Invalid argument 192.167.x.x is surely a wrong address due to a typo, so I don't know how your scanner is configured, does it use dhcp to get its address, or is it static ? Maybe this is to double check, both in the scanner and in /etc/sane.d/pixma.conf If you still encounter this problem, you could also try to check if the situation is the same with usb. In the meantime, I'll commit the successful changes for the Pixma MX350, thanks to your feedback. Nicolas Le dimanche 04 juillet 2010 ? 19:13 +0200, Guenther Hutzl a ?crit : > Unbelievable!
