摘要
A method of controlling liquid movement to and from a liquid ejection device (such as an ink jet printing device) having a nozzle chamber, a liquid ejection aperture in the nozzle chamber and a movable element located within the chamber for displacing liquid through the ejection aperture. The method comprises actuating the movable element so that it moves from a quiescent first position to a liquid ejecting second position with a first average velocity and so that it returns from the second position to the first position with a second average velocity lower than the first average velocity.
