摘要： A method of determining whether a flow path is ready for ejection includes supplying liquid to the flow path, which includes a pumping chamber and a nozzle, after supplying fluid to the flow path, applying energy to an actuator adjacent to the pumping chamber, measuring an electrical characteristic of the actuator to obtain a measured value, and comparing the measured value to a threshold value to determine if the flow path is ready for ejection.

摘要： In the embodiments of the simplified ink jet head described in the specification, a carbon body is formed with ink passages, such as internal passages extending through a carbon plate, pressure chambers on one side of a carbon plate, flow-through passages on the other side of the same plate and ink supply passages, and a piezoelectric plate is affixed to the pressure chamber side of the carbon plate by a thin layer of epoxy adhesive. The piezoelectric plate may have a conductive coating on one side which is photo-etched to produce an electrode pattern corresponding to the pattern of the pressure chambers in the carbon plate. An orifice plate may have specially profiled orifice openings to assure axial projection of drops and may be affixed by a thin layer of epoxy adhesive to a carbon plate having orifice passages supplying ink from the pressure chambers to the orifices. Since the carbon plate is conductive, it can be used, if desired, as an electrode on the opposite side of the piezoelectric plate and, to assure grounding of the piezoelectric plate, a conductive epoxy adhesive may be used to bond the piezoelectric plate to the carbon plate. Moreover, since the carbon plate is porous, it can provide a communication path between a vacuum source and an air-permeable, ink-impermeable layer on the ink passages to remove dissolved air from the ink in the passages. In one alternative embodiment, an ink jet head assembly contains two separate carbon pressure chamber plates, a carbon manifold plate and a carbon collar to retain the carbon plates in an assembly.

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.
