This is a "call to arms" for all of you Canon customers who have had this problem and have had their printers disabled because of it. Please respond with the model of your printer and if you were able to fix it, what you did to fix it.
We need to put pressure on Canon to respond this product defect. It appears to be bad firmware that does not allow the user to override the problem and to continue to use the printer even in a degraded mode. From my investigations the problem is NOT a printhead issue - no way one can be printing fine and then have this error alert without having changed the printhead or ink cartridges!
Canon, PLEASE take this issue seriously and provide a solution across the affected models. If nothing else there should be a trade-in allowance for those printers that have been affected by this product defect.
I have had many Canon printers because they have superior functional specifications. I want to be able to continue using Canon products but only if I can have confidence that this product defect will not destroy my investment.
If Canon is unresponsive our next step should be to aggressively publisize this product defect on social media and on major product vendor outlet sites as negatives reviews.
Forum Users, please reply with your affected model number(s) and with details of any succdessful fix procedure.
I was about to buy an MX922 printer this week, as it received great reviews from several sources. But after discovering this crazy printhead error that seems to be common in many of Canon's printer models, I'M GONNA PASS.
I've used Canon cameras for ages, and haven't had significant issues. But man....HEY CANON! FIX YOUR PRINTHEAD ISSUE INSTEAD OF PASSING THE HASSLE ONTO YOUR CUSTOMERS!!!
Seriously.....I'm so glad I came across this forum thread. Shame on you, Canon.
There's no way I'm gonna take a chance with your printers.
I always buy Cannon Printers. This may need to change. I have a Multifunction unit MG6250 without runnijg out of ink or changing anything it had this U052 Wrong Print Head error. I did exactly what the cannon sight said and nothing changed. If I try to clean the print head (looks ok but I'll try anything now) then see if that works. Printers are cheap enough if this doesn't work I'm buying another brand.
I had this problem about six months ago (Pixma MG5550), i tried re-seating the head and even tried the head of a friend that has the same printer as me and nothing worked.
What did work for me was playing with the white flat ribbon cable that connects the head to the main board. Nothing fancy, i just pulled it a bit to either side, just played with it a bit (gently of course, so i couldn't damage it) and guess what, as soon as i lowered the cover, the error went away and it has been working since then. I didn't disassemble the printer, just did it with the cover up.
