After power-cycling the device, it reported that its IP address had changed back to 192.168.0.10, and it is now found: $ scanimage -L device `pixma:MF4800_192.168.0.10' is a CANON Canon i-SENSYS MF4800 Series multi-function peripheral Question: Since link-local addresses in 169.254.0.0/32 seem to be every bit as local as addresses on the local subnet, would it make sense for SANE to search for networked scanners on 169.254.0.0/32 in addition to the local subnet?
