Thanks, Mark. In the elegance stakes, that solution scores zero, I'm afraid! Fortunately, by updating MP Navigator to v4.0.5 and reinstalling the IJ Network Tool in its latest version, all problems with my MG 6150 have been overcome. Took me a couple of hours to sort that out and I would have hoped for an auto-update from Canon, to be honest, but the job's done, thankfully. Hopefully this might help other sufferers.
Having fixed the MP Navigator and High Sierra through your helpful forum, I am now having the same issue with MP Navigator and Mac OSMojave can you please help.
My Canon Pixma MG 8150 has ceased working
again after updated my iMac to the new MacOSMojave.
I had the issue of not being able to scan on my Canon MX340 after updating to High Sierra on my Mac. I followed the instructions listed by GenoBarr in Message 159 posted on 5/22/15 and have been able to scan now. In #1 of the instructions it says to click on El Capitan; since I had High Sierra, it said there was nothing to download. But I changed it to El Capitan and downloaded that. After downloading and installing the things in that post, I clicked on the "Solution Menu" icon and it still would not scan.
So I went through Finder, clicked on Applications, Canon Utilities, MP Navigator EX, then on MP Navigator Ex 3.1 app and was finally able to scan pictures. It was a long detour but glad I can scan again.
I own an MX410 and can't find a version of MP Navigator that works with High Sierra. I purposely waited a long time to upgrade to High Sierra just so I wouldn't run in to compatibility issues. If I don't find something that works, I will definitely be divorcing Canon for good. Holler if anyone found a solution.
