Hello, I have just installed a new Canon iSensys MF746Cx on Ubuntu 18.04 and I can't get it to scan. It' connected over the network. I haven't found any driver or software for scanning on Canon's Website, so I was hoping I could do it with sane. I have read on the list of supported devices that the MF741/743 are fully supported by the pixma backend.
So I activated the pixma backend in /etc/sane.d/dll.conf by uncommenting it and edited the /etc/sane.d/pixma.conf file by adding "bjnp://address.here:8612". Scanimage -L gives me this message: [bjnp] udp_command: ERROR - no data received (timeout = 5000) [bjnp] bjnp_init_device_structure: Cannot read mac address, skipping this scanner [bjnp] udp_command: ERROR - no data received (timeout = 5000) [bjnp] add_scanner: ERROR - Cannot read scanner make & model: bjnp://192.168.2.103:8612/timeout=5000 Because CUPS adds the printer with the ipp protocol on port 631, I tried with other things as well (port 631, ipp protocol, net) but I always get the same error messages. My Epson WF7620 works great with both the "epson2" and the "epkowa" backends. Any help would be appreciated. Thank you.
