Question about Canon PIXMA MP780 All-In-One InkJet Printer

"Wrong cartridge" error when in fact it is the right cartridge

Our Pixma MP780 has the alarm flashing and says 'wrong cartridge' but we actually have the right cartridge in place. We've turned the machine on and then off again but still it's not correcting itself. We had this problem a few weeks ago, bought a new cartridge (even though we already had the right one inserted) and were able to print and now, all of a sudden the same error is appearing????

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

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.
