FLUID-JET DISPENSING DEVICE

摘要

Systems, methods, and other embodiments associated with fluid-jet dispensers are described. In one embodiment, a method (400) controls a fluid jet dispenser. The fluid jet dispenser includes a plurality of nozzles for precisely ejecting fluid and a plurality of ejection chambers. The fluid-jet dispenser includes one or more fluid channels for supplying fluid from a fluid reservoir to the plurality of ejection chambers and corresponding nozzles. The method includes detecting (405) that the fluid-jet dispenser has not ejected fluid for a predetermined time. The method applies a de-prime pressure (410). The de-prime pressure is a negative pressure to withdraw fluid from the nozzles and the ejection chambers to a high capillary force area within each of the one or more fluid channels to remove fluid from the plurality of nozzles.
