    Canon MX850: U052 error (wrong print head installed)

    My stratman , aren't we getting philosophical? Couldn't resist? You know what I meant When a tire wears out we say "oh well I got 65000 miles out of it". When a door handle breaks we say "holy @#$% I never saw one of those break before".

    Canon MX850: U052 error (wrong print head installed)

    Hi stratman. Whether you go by tanks or pages it looks like it comes to the same idea that a print head has a life span and eventually wears out as opposed to some mechanical part that may or may not break, like a car tire vs a door handle.

    Canon MX850: U052 error (wrong print head installed)

    After looking at the motley assortment of available printers and the bad reviews, I took a shot and ordered a new print head direct from Canon for $59, delivered. It was even cheaper than eBay or those direct imports from China from Ali Express. Now and then you win one. It just came, I threw it...

    Thanks again Peter. I'll take a shot with a new print head. In the event that that it does not fix it I will need a new printer. You found additional shortcomings in the MX922 that I didn't know about. Is that still my first choice, even if I were to spend more? The MX922 is under $100 and...

    Canon MX850: U052 error (wrong print head installed)

    Thanks Peter. Your advice is about what I got from the Canon tech rep., though your explanation of the relation between the print head sensor and logic board electronics made things a lot clearer. I am in the U.S. and the best price for a head was directly from Canon. The want $59 for the print...

    Canon MX850: U052 error (wrong print head installed)

    This is the original print head so it is clearly not the wrong head. I found a Canon bulletin that suggests removing the ink cartridges and print head and unplugging the machine for 5-10 minutes and then putting it back together if you get this error. I flushed the print head with water, as I...
