Through trial and error and some help from Mike at precision colors I've learned how to clear an ink starved printhead from a Canon Pixma Pro-100 printer. I also cover steps and tips to avoid getting another clog.
Printhead cleaning solution: 10 Parts distilled water, 2 parts Isopropyl Alcohol, 1 Part Ammonia (can be increased for stubborn clogs).
