Canon Pixma ip4300 won't print text and won't print the pgbk test pattern

Genki I don’t think you will ever remove all the dried pigment ink out of the print heads internal maze.

If you want to break loose some more of that pigment you might want to add some isopropyl alcohol to your cleaning formula.

I swear some one across the pond should start selling Windex in relabeled bottles.

@Genki You could also try using a window cleaner with ammonia as cleaning fluid. I don't know your location, but in the US the original Windex with Ammonia-D is recommended. Another suggestion is to use pharmacist's cleaning solution. It is the solution with the ammonia added.
