Very cool. How much pressure do you apply? Have you ever damaged a head?

I tried this with my print head for the HP8610 and it never fixed the issue. Kept telling me my cartridges were damaged even though they were new. 😮‍💨

Have you had luck cleaning a printhead from a 476dw that will not clean up through the recovery process? Yellow is 90% gone. Cyan has some bad streaks.
