Overnight my Canon MP780 started showing a "wrong cartridge" message on the display. I only use OEM cartridges. One was low and I replaced it, with no effect. I've turned it on and off, no effect. The Canon website said to take out the print head, put it back in and realign it, no effect (couldn't realign as wrong cartridge message still shows.) The closest repair center is 145miles away on another island, so not an option. Any suggestions?

Hi and welcome. I'm not familiar with Canon, but, I do know that HP cartridges have a built in chip with an expiration date. Regardless of the fact that you just opened it and inserted it, you get an error message. Not right, not fair....but true.

Thanks for the reply. These cartridges don't have the chips that came in later models. Can't figure out why this is occurring
