Canon Pixma MP 780

My printer/scanner/fax/copier has a message "wrong cartridge". When I take the cartridge out and replace, still get the same message.

This may seem to be a stupid question but, is it the right cartridge?

Is it a genuine Canon cartridge or an aftermarket replacement that "suits" your printer? If the latter, try getting a genuine Canon cartridge and install that and see if you get the same error message.

If you still get the same message, take it to a repairer and get them to check it out for you.

Good luck.

Wrong cartridge on Canon means the printhead has gone bad, nothing to do with the inks. You just need a new printhead. The part number is on the side of the printhead and starts with QY6-

"Wrong Cartridge" Message is being displayed on the Canon MP 780


Remove the print head and cartridges.Unplug machine for 30 min.
Repower and reseat head and ink do a head alignment.
If this does not correct it may require service.
Ink Cartridges are the BCI6 and 3 series correct?
If using CLI8's and they are flashing red you have a bad cartridge or it is in the wrong location.If so Canon will replace the bad cartridge.

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.
