摘要： The present invention is directed toward an improved heater chip for an ink jet printer. The heater chip has a diamond-like-carbon coating that functions as the cavitation and passivation layers of the heating elements on the heater chip. To improve the efficiency of the heater chip, the diamond-like-carbon coating is surrounded by a material that has a lower thermal conductivity than diamond. This surrounding layer limits thermal diffusion from the heating elements into the heater chip. A smoothing layer of tantalum is deposited over the diamond-like-carbon layer to insure that vaporization of the ink occurs at the ink's superheat limit. The diamond-like-carbon layer is preferably less than 8700 Angstroms in thickness such that less than 1 microjoule of energy is required to expel of ink droplet having a mass between 2-4 nanograms.

摘要： An ink jet print head has first nozzles of a first diameter for ejecting droplets of ink having a first mass, and second nozzles of a second diameter for ejecting droplets of ink having a second mass. The first diameter is larger than the second diameter, and the first mass is larger than the second mass. First and second heater-switch pairs are connected in parallel on a substrate of the print head. The first heater-switch pairs include first heaters adjacent corresponding first nozzles, and the second heater-switch pairs include second heaters adjacent corresponding second nozzles. The first and second heaters are composed of electrically resistive material occupying first and second heater areas on the substrate. The first heater-switch pairs also include first switching devices connected in series with the first heaters, with each first switching device developing a first switching device voltage drop as a first electrical current flows through. The second heater-switch pairs include second switching devices connected in series with the second heaters, with each second switching device developing a second switching device voltage drop as a second electrical current flows through. The first heater area is larger than the second heater area, thus matching heater area to nozzle diameter to provide for more efficient transfer of thermal energy to the ink. The voltage drop across each first switching device is substantially equivalent to the voltage drop across each second switching device, thus reducing undesirable nozzle-to-nozzle variations in the amount of energy delivered to the ink.

One such head includes a substrate having a thermal conductivity ranging from about 1.4 W/m-° C. to about 148 W/m-° C., a fluid ejection actuator, and a thermal bus thermally adjacent to the substrate and configured to dissipate heat associated with the operation of the actuator.
