Error U052 on Canon printers

MAJ 08/07/14

Error U052 appears on these Canon printers: MX850, MP540, MP530, MP600, MP610, MP970 and others...

Message error: The type of print head is incorrect install the correct print head U052



Solution 1:
  • Remove and replace the cartridges.

Solution 2:
  • Insert new cartridges

Solution 3:
  • Reseat the print head to correct print issues or clear error.

Solution 3a (thanks to Tony LeBaigue):
  • Remove the ink cartridges.
  • Remove the printhead: cleaned the rear contacts with a cotton bud and surgical spirit.
  • Left the part 5 minutes to dry.
  • Install the printhead and the cartridges.
  • The printer wil be into printhead clean mode and will return to normal mode.

Judging from all the posts I see on this very same problem, as well as my experience, this is a manufacturer's problem, a system defect. I've got this error and it is THE SAME print head that came with the printer. Genuine CANON cartridges, always. Canon printers never have impressed me and the service is worse than none.

I was happily printing things, then went to print something else and this error message came up. Talk about great timing..NOT. I am in the middle of sorting my accounts for my tax return :-(. Now it is going to take me time to sort this that I don't really have.

Same problem here with original print head and Canon ink cartridges only. Found a forum where a few folks tried rehabbing their existing print head. They ran water through the print head until the water ran clear, then allowed it to dry thoroughly before re-installing. A few claim it worked. It didn't work for me,same old U052 message, but it also didn't cost me any extra money...

What is so frustrating about this error is that it makes the unit completely inoperable. The scanner is still perfectly functional, bur I can't use it because the printer error message takes over the whole unit!

Looks like the next step is to try a replacement.

Our printer did this last night. We recently upgraded our Mac laptop system software (or whatever) and when I tried to print a Word doc, the error message popped up and wouldn't leave. I left the printer turned off overnight and the message was gone this morning. I used it this afternoon to print some Adobe files with no trouble but when I tried again to print the Word doc it popped up again. So I turned the printer off, made a pdf of the word doc, and then printed it.

Canon says this is an internal malfunction that will require service if standard cleaning did not fix this.

Thanks everyone. I've tried all the tips with no success. I will be purchasing a new printer which will not be a Canon.

I too will fix this problem by replacing this Canon u052 problem with a new printer. It's amazing how much support was given to Canon by the "techs" who sold out!

Dopo aver fatto anche io ciò che dice Jaime, sono molto contrariata dal fatto che una multifunzione diventi una zero funzioni solo per la testina di stampa.

I had the same error code. I removed the ink cartridges (not canon) and the print head (make sure you don't touch the underneath inking element or the rear contacts)and then cleaned the rear contacts with a cotton bud and surgical spirit. Removed a fair bit of blue coloured dirt. Left the unit 5 mins to dry and then put it all back together. The printer then went into print head clean mode on its own (5 mins) and afterwards back to normal - I hope this works for you too.

Canon consumers should be aware there is a known defect with the PIXMA MX print heads that Canon has been hiding.
Federman & Sherwood has filed a consumer class action lawsuit against Canon USA, Inc., and was brought on behalf of all consumers who have purchased certain defective printers manufactured and distributed by Canon USA, Inc. Thus far, at least 16 different Canon printer models have been identified that display an error message of "U052: Wrong Printhead Error," after limited use. This error indicates that the printer does not recognize the printhead, or that the printhead itself is faulty, but disables all functions of the printer, including scanning and facsimile capabilities, rendering the printer unsuitable for its intended purpose and use.

Regretfully I too have have the same UO52 error which appeared out of nowhere. Have tried all suggestions I have read online with no luck. Waiting for return email from Canon but not expecting much help based on what I've read. Never again another HP and now Canon.

Idem come tutti gli altri post.. le ho provate tutte .. ma niente da fare...è completamente inutilizzabile...ora capisco perchè lho pagata 99 euro in offerta da Euronics...gli altri amici miei che ho invogliato(purtroppo)ad acquistare.. per lo stesso problema, le hanno buttate nell'immondizia almeno dal 2012.....che delusione.. mai più canon

U052 Cost me a day fooling with my mx5320 JUST out of warranty, but nearly new w barely 100 pages printed in graysCale text mode- but still halfway into black cartridge #3 to add it all up it costs a buck or 2 per page to print plain text WHAT A BUNCH OF CRAPOLA!

I never even got around to using the scanner or fax machine and it still has the original film cov3r on it. No dust or wear even, but now it's a frigging brick grrrr.....

CANON I will never buy your products again-NEVER!

how do you remove the print head? would like to try the cotton swab cleaning

UO52 code and I followed the usual instructions and removed all CANON ink cartridges and removed the print head. Washed the print head with hand warm tap water until no ink color was apparent. No scrubbing just water. Installed everything (twice) and still UO52. I looked at the gold contacts on the print head and they looked clean. Since I had nothing to loose I decided to clean them with pure 96% alcohol (isopropanol will also work) and a make up cleaning pad. To my amazement it worked! It was an electrical contact issue... We will see how long it will work...
