Abstract
In one embodiment, a printing system includes a printhead module that has a printhead and a regulator chamber. The regulator chamber contains ink and a regulator air bag. The regulator air bag and the printhead are in fluid communication with the ink, and the printhead includes a plurality of ejection nozzles. The printing system includes a pressure source to inflate the air bag, thereby displacing an amount of ink sufficient to agitate menisci in the ejection nozzles without pushing ink out of the nozzles.
