I have a Canon MG5420 printer. Changed an ink cartridge multiple times same as used before and keep getting error code wrong print cartridge.
JA: Has your Canon done this before? And can you guesstimate how old it is?
Customer: No. This is first time. It's around 23 months old

Customer: Windows 7. The error comes up on the printer. It shows the print jobs on the computer.
JA: How long has this been an issue? What happened right before this popped up?

Lets focus on the most recent cartridge you changed when you received this error.

Remove that cartridge, then we need to clean the electical contacts on the cartridges, and also clean the electrical contacts inside the printer that read that specific cartridge.

In this image, you can see the electrical contact on the bottom of the cartridge.$/12PK-PGI-250XL-CLI-251XL-Ink-SET-Chip-For-Canon-_1.jpg

You want to clean it with a lint free cloth and a drop or two of windex, or rubbing alcohol. Or warm water if thats all you have. Clean it, and dry it.

Also, theres a contact inside the machine that reads the electrical contact you see on the cartridge, clean that too.

Then, unplug the machine from power and hold the power button while you plug the machine back in.

Then, insert the ink cartridge when it asks.. Do you still get the error or is all well now?

I strive to provide great service, and greatly appreciate a 5 star rating clicked and submitted when you are satisfied. If you do not submit a rating, I am in no way credited for my time. I always answer follow up questions.

The error screen is coming up on the printer not the computer. The computer shows the printer connected by WI-Fi and lists the unprinted works ready for printing.

Right.. I assumed the error was on the printer, and if you read the steps I sent you they focus entirely on the printer.. I didnt mention the computer as the computer cant help us fix the issue!
