U052 Incorrect Printhead TEMPORARY Bypass
Canon MX700 printer printhead diagram
NOTE: Scroll down to “Reseating the Print Head” to see the print head
diagrams of print head nozzles, electrical contacts, ink supply ports.
1. I have successfully TEMPORARILY bypassed the U052 incorrect print
head error on my 11 year old Canon MX700 printer by thoroughly
cleaning the print head as follows. The U052 error REOCCURS after
printing on my printer and with the passage of time (i.e. a few days).
I believe I saw this fix on the Canon Community Forum.
a. Get a flat bottom container and fill it with a 1/4 inch of warm water
and put your print head with the print head nozzles pointed down
in the water. See print head diagram web link above.
b. Drip warm water onto the ink supply ports too.
See print head diagram web link above.
c. Jiggle the container to jostle the print head to get the
d. Repeat steps a, b & c until your water remains clear
(i.e. no ink remaining).
e. I dried my print head with the following: paper towels,
setting it under a desk lamp, air drying overnight.
2. With a clean print head I do not get the U052 error.
3. After printing on my printer a dozen color pages successfully-
1 week later I get the U052 error. Cleaning the print head
per note# 1 above and the U052 error goes away.
Other notes include:
1. I cleaned the print head gold contacts & interfacing pins with
CRC Electronics Cleaner & Q-tip. This cleaner is available
from an Auto Parts store. This cleaning did not resolve the
2. Previously cleaned the print head gold contacts with a pencil
eraser which resolved my U052 error. However, a few days
later the U052 error came back.

I had a long chat with a Canon Canada service tech today about the U052 error msg. He advised that it is a poorly worded general error msg that has been refined in later printers to be more specific about the error. It can be caused by a verity of issues within the head or outside such as cartridges or wiring behind the contacts. He suggested the overnight soaking which I have already done and swapping the printhead with another similar printer, again which I have already done. He could not come up with any other suggestions for me to try other than buying a new printer.

Would love to know if there is any resolution to all of these printer complaints. I, personally, would love some answers, Seems like something is obviously defective for everyone to have the same problems.
Error 1403, MX922- "The type of print head is incorrect. Install the correct print head." Many post are over 5 years old. It's 2019 and still experiencing same problems.

Same issue, stopped suddenly while printing, and have had/used the same printer head (factory) for years (almost 10)!

Still happening. My MG5350S has just come up with the same u052 error message. I have now wasted two new print cartridges and cleaned the printhead, but it is still not working. Very disappointing to see that Canon have completely failed to resolve this issue.
I guess that I'll be buying a new ptinter tomorrow. Hmm, what brand shall I choose? Will it be Canon? Not blxxdy likely!!! I am mad, so goodbye Canon.

I am as mad as an entire nest of wasps, right now! My husband bought me the Canon Pixma MX892 a few years ago because I still have my last Canon printer (a BJC-50, which was one of the first portable printers available) and it still works. I wanted to upgrade and loved my Pixma MX892! That was until today. Right in the middle of printing pictures for a memorial for my cat that just died, I got the errors B200 and then the U052 error message about having the wrong print head! I have always used Canon brand printer cartridges and have always kept up on all the required maintenance of this printer. There is absolutely no reason for a printer that's only a few years old to just stop working! Especially when I still have another Canon printer that is much older, that has no issues!
Canon: I've seen countless people on countless forums with this same problem, with multiple models of your printers. You owe it to your customers to do something about it! Give us a trade in value, towards a new printer, or something! I have been a long time customer. I've bought multiple printers, cameras, and endless amounts of printer cartridges, none of which have been cheap! I've always used brand name cartridges and followed the instruction manuals and maintained my printers well. This is inexcusable!
I am now setting out on a mission to blast the internet with the message that Canon, knowingly, makes faulty printers. I am going to post to social media using various hashtags to make sure I reach as many people as humanly possible. You can't keep selling bunk products and stay in business. Eventually, enough people will hear about it and stop buying your products. I don't care if I have to stand in front of Best Buy with a sign, I'm going to make sure people know about this! Lots of people!
I will never buy a Canon product, again!

I have been using my Pixma MX892 for six years and suddenly it displayed the dreaded U052 wrong printhead code. My previous Canon printer did the same thing after only 3 years of operation and customer service suggested that I replace it and she gave me a significant discount on a new printer. With 2 consecutive printers being disabled by the same code and no official instructions on how to fix it, other than buy a new one, I am switching to a different manufacturer.

i just want to thank all those in the community that offered fixes. I have about $100 in ink for my MX922 so I had to try, but alas nothing worked.
Likewise, I would like to thank Canon for their silence on the matter. That made it an easy decision to buy an Epson ecotank ET-3750. It included a bathtub of ink, setup and software installation were a breeze, and the first pages just rolled out of it. No guarantees this experience will be better, I realize that. But I'm happy to give it a try.
