I have the same issue with Pixma MP610 from 2008.
The printer is otherwise in very good state.
I see no reason, why also scanner should be harmed by this error. Could someone help how to get at least scanner working?
Thank in advance for any help.

Same issue with a MG6650 multifunction printer. None of the suggested solutions has worked so far. Not willing to buy a print head to see if that works.

Haven't responded to these many posts for so long as it became so frustrating, but here's the answer, as many of my more learned colleagues and so many, many other posters will know. You have two choices. 1. You can keep posting requests for details, & trying the many options like changing print heads; using whole new sets of branded inks; writing to Canon: reading through many years of Forum posts, including the success of a Class Action Lawsuit in America (which changed nothing in terms of future Printers!); OR 2. you can stop all the stress, as I did eventually, and go out and just buy another printer!

My MX 870 threw the U052 code this morning after I replaced an ink cartridge. My search brought me to this forum. Needless to say, I was very discouraged by what I read while waiting the 10 unplugged minutes called for in the Canon reccommended "fix"
I restored power, the printer turned on and......the message was gone!

U052 Incorrect printhead error
FIX: Clean printhead “gold” contacts with a pencil eraser
Notes: All previously tried youtube fixes failed.
Printer: Canon MX700

I have two Canon MG5220. One of them suddenly showed the U052 Printhead error msg. I swapped the printhead into my other MG5220 printer and the error moved with the printhead. I swapped the printhead back and the error stayed with the printhead. Next I will try a long soak in water to see if it makes a difference.

An overnight soak of the printhead and a thorough cleaning of the printhead docking station did not fix the problem. I now have only 1 MG5220 printhead but two otherwise fine working printers.

I'm convinced that the printhead is NOT the problem. The problem is CANON printersl and the Canon company. I, for one, will never buy another Canon product. They apparently settled a class action lawsuit, but continued to sell their defective product. I know because I had one, but never more.
