摘要： A fluid ejector head includes a die with a plurality of fluid ejector units, each fluid ejector unit comprising a pumping actuator having a drive electrode, and a manifold that contacts the first side of the die to define a module volume in fluidic communication with a drainage volume. The module volume is defined in part between the manifold and at least a portion of plurality of fluid ejector units, and the drainage volume is located apart from the fluid ejector units. The module volume, in comparison to the drainage volume, has a greater ratio of interior surface area to volume or has a greater percentage of interior surface area covered by a non-wetting coating.

摘要： Methods, systems, and apparatus for drive a pumping chamber of a fluid ejection system are disclosed. In one implementation, the actuator for drive the pumping chamber includes a continuous piezoelectric layer between a pair of drive electrodes and a continuous reference electrode. The pair of drive electrodes includes an inner electrode and an outer electrode surrounding the inner electrode. The actuator is further coupled to a controller which, during a fluid ejection cycle, applies a negative voltage pulse differential to the outer electrode to expand the pumping chamber for a first time period, then applies another negative voltage pulse differential to the inner electrode during a second time period after the first time period to contract the pumping chamber to eject a fluid drop.

摘要： In the embodiments described in the specification, electrodes are bonded to the surface of a ceramic piezoelectric layer by supporting electrodes having a reduced dimension on a flexible dielectric film and placing the dielectric film under tension to expand the film and the electrodes sufficiently to conform the electrodes to the desired electrode pattern on the ceramic piezoelectric layer. The electrodes are then bonded to the piezoelectric layer with an adhesive bonding agent under pressure applied hydraulically so as to be distributed uniformly throughout the surface of the piezoelectric layer. In one embodiment the dielectric film also carries conductor arrays for connecting the electrodes to remote driver chips at locations spaced from the surface of the piezoelectric layer.

摘要： In the representative embodiments of the invention described in the specification, an ink jet head has a series of aligned arrays of ink jet orifices arranged to project drops of different colored inks in sequence to the same location on a substrate during each scan of the ink jet head adjacent to the substrate. The spacing of the orifices in each aligned array and the speed of the ink jet head during the scanning are arranged so that all the ink drops applied at the same location on the substrate are applied in a time period of no more than about 100 milliseconds and preferably no more than 50 milliseconds. Moreover, to avoid banding the lines produced by successive scans of the head are interlaced so as to produce a periodic frequency of no more than about four lines per millimeter.
