Question about Canon PIXMA MP780 All-In-One InkJet Printer
Inkjet printers need to be used frequently to prevent inkdrying out in the print head nozzles.
If the print head cleaning maintenance routine does not clear the blockages,then print head needs replacing, but it may be expensive.
It may be more cost effective to buy a later model and better printer thanreplace the print head.

First of all the print head is clogged just because you have tried to print repeatedly while some of the cartridges are empty. This results ink burn in the nozzle and clog. My recipe: Heat some drinking water in the kettle (70-80 C). Put the head in it and shake gently several times until ink is completely clean (10 minutes). Change the water do the same again. Change the water again (70-80 C) this time put a spoon full of apple vinegar (becomes a natural acidic solution very dilute) shake again, clean with cotton stick. I did it and started to love my mp800 again as much as I just bought it, all colours come back and started to print superior photos again......
