20100079523 | Control of Velocity Through a Nozzle - A method is described wherein one or more parameters are measured that affect the nozzle velocity at which a printing fluid is ejected from a pumping chamber through a nozzle. The printing fluid is contained in the pumping chamber actuated by deflection of a piezoelectric layer. A surface area of an electrode actuating the piezoelectric layer is reduced based at least in part on the measured one or more parameters. Reducing the surface area of the electrode reduces the actuated area of the piezoelectric layer. | 2010-04-01 |
