Just wanted to leave some useful information to those who have this problem. I have a TS 9020 and it had the "type of print head is ioncorrect" message. I couldn't get rid of it no matter what I did. Eventually I removed the cartridges and put it in printhead install position (holding stop until head moves to correct place). Then I got a flashlight and examined the pins on the printer to see if something was stopping them from making contact. I found that 1 pin was bent and also there was dust on the pin connection. I was able to CAREFULLY straighten out the bent pin with a small plastic spudger from a cell phone repair kit. I brushed off the dust with a small soft bristled clean craft brush. After putting back the cartridges and closing the cover, the message went away and the printer has begun printing normally again!

Canon MG7160. Similar printer error was Support code 1405 (incorrect print head).
I followed the suggestions offered here and everywhere else.
1: Opened front cover
2. Wait until the head assembly moves to the middle.
3. Removed all the print cartridges.
4. Removed the power cable to power the printer off.
5. Moved the head assembly 1CM to the right.
6 Pulled back the head release lever.
7. Removed the print head.
8. Examined the contact surface (brass coloured). It looked clean.
9. Examined the pins inside the printer that the contact surface mates with. That looked clean also.
10. Cleaned the contact surface with iso-propyl alcohol and a lint-free cloth. It came up very dirty! All purple.
11. Cleaned the pins inside the printer. VERY carefully!. Examined them for any damage. All ok.
12. Re-inserted the print head, and while holding it towards the back of the printer, pushed the head locking bar back in.
13. Reassembled the rest of the removed parts, cartridges etc.
14. Tested. ALL OK!!
Prints ok now.
Thank you all!

I have a Pixma MX922, lightly used but over 2 years old, that is showing this message. Yes, I performed all of the obvious troubleshooting stuff (resetting the printer, cleaning contacts and replacing, and so forth). I am an engineer with a extensive experience working with and designing large, complex instrumentation.
My impression from Canon's postings on this forum thread is that Canon's business model likely depends heavily on your local waste management services to meet its yearly profit targets. This is still commonplace as with most other consumer technology products. Despite a lot of lip service paid to environmental concerns, the expectation from the business owners is that you will put this relatively large hunk of plastic in the garbage to slowly degrade over the next million years and buy a complete replacement product every 2-4 years, even though there is absolutely nothing wrong with most of the parts (and particularly not with the plastic ones!). Is there really that much new happening in printers in the 2020 decade and beyond that the consumer gains something by replacing them this freqently? I don't think so.
There is an awful lot of inventory of equipment and goods to manage in today's household. Having a house full of devices that need attention relatively frequently is a big waste of time when you add up the time spent over millions of printer consumers.
It is 2021. A printer at this point should be like a hammer and should last at least 20 years. Can Canon do us all a favor and finally provide a printer that is fit for the current era? I'd like to see that!

I installed a new print head and it still gave me the error message. I had to order a new printer. It was not that old.
