Go to canons website for troubleshooting your printer, fastest and quickest way to resolve this. good luck
secondly, in the applications folder on your system should be an icon for your printer. dbl click, this might be able for you to find out cartridge settings. good luck

You get that message when the printhead goes bad. It's not the ink cartridges. You need a new printhead

My canon pixma mp780 printer is giving the message "wrong cartridge". I did have a non canon ink cartridge in there, but now the cartridges are all canon, and I am still getting the "wrong cartridge"...


1. Remove the front printer cover.
2. Then take out the ink.
3. Next pull up the gray lever and take out the printer head.
4. Now go to the sink and start running the hot water. Then slowly and gently run the hot water over the metal part of the printer head. Use a soft tissue and gently clean the dry ink out.
5. Now dry the printer header with a soft cloth and wait for it to dry before placing it back into the printer.
6. Turn on your printer and see if it works now.

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.
