Patent abstract
In an embodiment, a method of degassing ink in a fluid ejection device includes generating a localized nucleation site within an ejection chamber of a fluid ejection device. An air bubble is formed at the nucleation site, and the air bubble is prevented from venting into an ink supply slot using a bubble-impeding structure. The air bubble is vented through a nozzle associated with the ejection chamber and into the atmosphere.
