Question about Canon PIXMA MX850 Multifunction Printer
Is there ink in the cartridge?
If so you may remove the print head and take a mixture of 1oz. ammonia and 8 oz. water (roughly 180 degrees) and let it soak for 30 minutes.
If you see some cyan ink come out you are on your way.
Now completely dry the head being careful of the nozzles.
I usually use an air duster can to blow off and let stand for a few minutes.
