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 method of cleaning an outer surface of a fluid ejector includes dispensing a cleaning fluid onto the outer surface of the fluid ejector, drying a region of the outer surface of the fluid ejector, and moving the region in a path across the outer surface of the fluid ejector to cause evaporation of the cleaning fluid along a front that moves across the outer surface of the fluid ejector A method of cleaning a surface of a fluid ejector includes dispensing a cleaning fluid onto the outer surface of the fluid ejector, the cleaning fluid including a solvent and carrier liquid that is more wettable to residue of fluid ejected from nozzles of the fluid ejector than the solvent and having a higher vapor pressure than the solvent, and evaporating the carrier liquid such that a concentration of solvent on the surface of the fluid ejector increases.

摘要： An apparatus for depositing droplets on a substrate is disclosed. The apparatus includes a support for the substrate, a droplet ejection assembly which includes a pumping chamber, a controller and a source of static pressure to maintain the total pressure in the pumping chamber above a threshold pressure level to avoid rectified diffusion type bubble growth in the pumping chamber. The droplet ejection assembly is positioned over the support for depositing the droplets on the substrate and includes, in addition to a pumping chamber, a displacement member and an orifice that ejects the droplets. The controller provides signals to the displacement member to eject drops.
