Public bug reported: While executing scangearmp2 reports "Cannot find available scanners", then it fails when "Update Scanner List". However I can print documents normally. This always worked for me using wifi.
I tried sudo apt-get purge scangearmp2 and installing from fresh. Firstly, using the package cnijfilter2-5.50-1-deb, which reports "Could not detect the target printer", but Ubuntu reports a window "Printer added Canon Ts_6151". After that, installing scangearmp2-3.50-1-deb, also fails. The printer/scanner is working normally from another laptop with windows 10.
