    摘要： An inkjet printhead with a plurality of nozzles, a bubble forming chamber corresponding to each of the nozzles respectively, the bubble forming chambers adapted to contain ejectable liquid, a heater element positioned in each of the bubble forming chambers respectively for heating the ejectable liquid to form a gas bubble that causes the ejection of a drop of the ejectable liquid from the nozzle; and, a print engine controller for controlling the operation of the heater elements; wherein during use, the print engine controller heats the ejectable liquid with the heater element to lower its viscosity prior to a print job; and during printing, the print engine controller ensures that the time interval between successive actuations of each of the heater elements is less than a predetermined time in which the viscosity of the ejectable liquid in the increases to a threshold.

    摘要： There is disclosed an inkjet printhead which comprises a plurality of nozzles (3) and one or more heater elements (10) corresponding to each nozzle (3). Each heater element is configured to heat a bubble forming liquid in the printhead to a temperature above its boiling point to form a gas bubble (12) therein. The generation of the bubble causes the ejection of a drop of an ejectable liquid (such as ink) through the respective corresponding nozzle, to effect printing. Each heater element is configured such that an actuation energy of less than 500 nanojoules (nJ) is required to be applied to that element to heat it sufficiently to form such a bubble (12) in the bubble forming liquid (which liquid can also be the ink). This configuration thus provides for a high efficiency printhead.

    摘要： A thermal inkjet actuator for use in an inkjet printer assembly includes heat conduction means arranged to realize a predetermined negative pressure profile to facilitate droplet formation. In a preferred embodiment the heat conduction means comprises a thin layer (54) of very high thermally conductive material such as Aluminium located in the middle of a non-heat conductive passive bend layer (56). The overall cool-down speed of the actuator, and hence the speed with which the passive bend layer returns to its quiescent position can be controlled by controlling the proximity of the heat conductive layer to the actuator's heater during fabrication.
