1. Remove the print head, then rinse under hot running water from the ink inlet side and then the nozzle side, do this back and forth until you don't see any ink flowing out.

2. Soad the print head for an hour in water, rinse again.

3. Soak the print head in a shallow container using Windex with Ammonia overnight.

Just put enough Windex to come up about an eight of an inch up the print head and cover the nozzles.

4. Rinse under running water again.

5. Shake the print head well to remove as much water as possible. Then pour isopropyl rubbing alcohol over the print head to remove water that you can't see on the printer circuit board side and dry the print head over night, or in sunlight, or a warn spot as you want to remove that moisture on the printed circuit board side that you can't see. If you don't remove that moisture you can damage the printer electronics (been there). Don't use a heat source, such as a hair dryer, as that could be too hot and damage the print head electronics.

NEVER RUB THE NOZZLE SIDE WITH ANYTHING OR DAMAGE COULD OCCUR.

Proof that some posts, no matter their age, are super valuable!  I just used this technique to clean my Pixma Pro 9000 print head and it worked like a charm!  Thanks Petruska!
