Canon pixma TS6151 scanner stopped working suddenly.

[Mijail Febres Soria]

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.

Thank you for reply

There's no CD/DVD installation media for Ubuntu. The installation is made through official support drivers. They worked so far up until around one month ago. What is curious is that the printer works normally as intended.
