摘要： Methods for improving the thermal conductivity of a substrate for a micro-fluid ejection head and micro-fluid ejection heads are provided. 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. Exemplary modified substrates have improved thermal conductivity characteristics as compared to a corresponding substrate not modified to include the thermal bus.

摘要： An apparatus and method is provided for compensating for the effects of thermally induced droplet size variations in ink-jet printers. The apparatus includes a temperature determination unit for determining the temperature of the print head, and a halftone adjustment unit configured to receive the print head temperature from the temperature determination unit and to receive image data in the form of nominal halftone values. The adjustment unit can increase or decrease the number of dots to be printed, and thereby compensate for droplet size variations, either by adjusting the nominal halftone values based upon the temperature or by adjusting a threshold array based upon the temperature. The temperature determination unit can predict the print head temperature by counting the number of dots to be printed by counting the binary halftone values fed to the swath memory.

摘要： A binary printer for printing halftone color images on a substrate so that the determination of whether to print a dot or to not print a dot of each color ink at each pixel location is based at least in part upon an estimated temperature of the print head. The temperature of the print head may be estimated based upon direct measurement of the ambient temperature and/or direct measurement of temperature of some portion of the print head. Alternatively, the temperature of the print head may be estimated by counting the number of dots fired by the print head.

摘要： The invention described in the specification relates to an apparatus and method for cooling a printhead containing multiple semiconductor substrates. The substrates which contain a plurality of energy imparting devices for energizing ink are attached to a metal substrate carrier for providing efficient heat transfer from the substrates. A temperature sensing device is attached to the carrier for measuring a temperature of the substrate carrier during a printing operation and for generating an input signal to a controller. The controller, in turn, sends an output signal to the printhead to selectively energize one or more of the energy imparting devices on each substrate in response to the input signal and a thermal expansion value based on the temperature of the heat transfer member. Because the timing of energization of the energy imparting devices is controlled in response to the carrier temperature and its expansion characteristics, more cost effective materials for the carrier can be used.

One such heater chip includes a resistive layer deposited adjacent to a substrate and a protective layer deposited adjacent to the resistive layer. The protective layer can be a tantalum oxide protective layer, which has a high breakdown voltage. An optional cavitation layer of tantalum, which bonds well with the tantalum oxide layer, may be deposited adjacent to the protective layer. Alternatively, for example, the tantalum oxide layer may serve as both the protective layer and the cavitation layer.
