Using my PIXMA MG6220 as a scanner no longer works

[BobbyF]

My trusty MG6220 printer has stopped working as a scanner. I print to it just fine via WiFi from 4 Win10 computers & a couple of iPhones. I suspect a troublesome Windows update, but don't have hard evidence. I have tried deleting all the old Canon drivers & reinstalling. Nope!
I have turned off all firewalls. Nope!

BTW, reinstalling always fails because the install program can't find the printer. Yet I can ping it's IP address, and I can print to it just fine, but as a scanner it's a ghost. 

What a hassle. Anybody run into this & fixed it? I've wasted the afternoon trying to solve the glitch!
