can someone help me here?

I am using a Canon MG5751 under Mint 18.3.

I already saw that this model isn't supported under Mint 18.3 (at least saw some threads about it)

However, I can print on it via WiFi Network. Also scanning is possible, but only in the CLI mode via scangearmp2.

Does anybody knows how to get this scanner working under Xsane?
