guys, i have two canon printers, Pixma MP780 and Pixma iP4000R. Do they have the same print head? Because i think my MP780 print head is broken, and i want to swap the print head just to make sure.
Yes... The Canon i860, i865, Pixma ip4000, MP750, and MP780 printers use the same printhead. If you need to order a new one, the reference # is Canon QY6-0049-000
