Question about Canon PIXMA MP780 All-In-One InkJet Printer
You should remove all inks and then lift the lever to remove the printhead. You can dab the bottom on a paper towel damp with water to clean old ink and paper dust off the nozzle area. Re-intalll printhead and inks, do at least 2 deep cleans, if not improved you will need a new printhead. The part number is stamped on the side of the printhead.
