Re: Hacking the Xaar 128 printhead

Gentle ultrasonic cleaning will clean the printhead. I have read that excessive ultrasonic energy can damage a head. There is an Ebay seller in Lafayette Louisiana who cleans heads for less than USD$100 each. This company did a couple for me and they turned out great. Xaar authorizes a number of com...
