Hello, I have a multifunction Canon MF746Cx and several machines: one Ubuntu 22.04 and one OpenSUSE Leap 15.5 (the others don't matter really).
In Ubuntu, when I run "scanimage -L" I get [00:06:02.547369] [bjnp] add_scanner: Scanner MF745C/746C is not supported, model is unknown! Please report upstream Created directory: /var/lib/snmp/cert_indexes device `escl:http://192.168.200.103:80' is a Canon MF745C/746C platen,adf scanner device `airscan:e0:Canon MF745C/746C' is a eSCL Canon MF745C/746C ip=192.168.200.103 so I am able to scan using the escl and airscan backends. On OpenSUSE there are no such backends in /etc/sane.d/ and I didn't find any option to install them (zypper doesn't find them in the default repositories). Also there is no dll.d direcotry under /etc/sane.d/ in OpenSUSE. Another thing is that in OpenSUSE, other than in Ubuntu, all backends are commented out in /etc/sane.d/dll.conf, so in order to try making it work I uncommented "pixma" because I thought it would be the closest to the right backend for my machine. I also tried adding in pixma.conf the line "bjnp://address.to.scanner" and "mfnp://address.to.scanner" and now "scanomage -L" gives me [00:17:39.635393] [bjnp] add_scanner: Scanner MF745C/746C is not supported, model is unknown! Please report upstream No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). "sane-find-scanner" doesn't find anything. How can I get this scanner to work in OpenSUSE too? Is there a place where I can download either "airscan" or "escl" for this OS? Thank you, Andreas
