Network scanner setup

The sane man pages refer to "backendname" a lot. http://www.sane-project.org/sane-mfgs.html gives the backend name for the 6250 as "pixma"

man sane-pixma (seems to be a man entry for each backend) tells you that network scanners should normally be detected, but if not, add them directly to /etc/sane.d/pixma.conf

Edit that file and add a line of the format:

bjnp://<ip_address>

IP address can be retrieved from the printer settings, or from the options in the printer itself.

After adding an entry for the printer, save pixma.conf

Now edit /etc/default/saned and set RUN=yes

Then: service saned start

Run xsane
