I have successfully configured a Canon Pixma MX494 as a network printer from my laptop (PureOS/Debian) using CUPS. It appears under "Printers" and I can print a test page over the network.
I can successfully scan over the network from my Android device using the Canon app.
I am now trying to configure the same device as a network scanner from my laptop.
Following https://wiki.debian.org/SaneOverNetwork#Client_Configuration I have:
- Uncomment the net backend entry in
- Added the IP address of the scanner to
/etc/sane.d/net.conf(Although, from the link "Note that the net backend is not for accessing arbitrary scanners over a network.")
- I can ping the scanner at its IP address from my laptop
scanimage -L does not detect the scanner. (It seemed to detect it once, but
simple-scan then failed, and it has not detected it again since then.)
