Thanks Aardvark. I did call Canon Tec Service when this happened. Got through quickly and the tech was as helpful as he could be but, of course, could not resolve the problem. His suggestions were the same as I found online. I've only used Canon ...
Pixma MG5220 failed with a U052 code today. What to do with those 8 unopened cartridges and a set almost full in the machine. I probably paid as much for the ink as the printer.
