also for openSUSE Leap 42.3 x86_64, see the section

See the section "Trouble-Shooting (Debugging)" at
First of all I would try to connect the scanner via USB,

If the scanner works again when connected via USB, the root cause
is likely related to the changes in your networking layer,
cf. the section "Scanning via Network" in
