More about : canon mp780 printer head buwish November 7, 2010 5:53:55 AM Is it an original canon cartridge or is it a re-manufactured one? If it's re-manufactured, some printers tend to recognize this and will give you trouble for it. In either case, I'd return it and get a new cartridge. Can't find your answer ? Ask !
