Pixma780 wrong cartridge

I suddenly started getting this error "Wrong Cartridge" on Pixma Mp780. I changed all of the cartridges (oem) but it has not helped. I am disabled on on a very limited income so I really need to know what the problem before I start spending a lot of money I don't have to fix it.

Re: Pixma780 wrong cartridge

If it is new, just call technical support. Chances are if it is in warranty, you'll get it replaced. I'd say do that before anything. Let me know otherwise

Error: ''Wrong Cartridge'' when no new cartridge has been installed

It is probably one of the cartridges. Usually, when the message "wrong cartridge" appears, the cartridge is faulty.

Receiving message stating "wrong cartridge"

Overnight I started getting the "wrong cartridge" message on my Canon MP780. I use only OEM cartridges. As the Canon website suggested, I replaced the printhead with a new one (Empire Office Machines for $48.25 plus shipping) and it works great. Prints better than ever. Easy fix for my machine. I did read that using refills can cause more problems than just the printhead.
