摘要： The present subject matter relates to evaluating nozzle condition of a plurality of nozzles. In one example, drive bubble detect (DBD) test results for a set of nozzles from among the plurality of nozzles are stored by a print head in a test result register, where the test result register is provided onto the print head. Further, status bits of a result-ready register provided in the print head are set to a predetermined value by the print head responsive to storing of the DBD test results in the test result register. Further, based on the setting, the DBD test results are obtained by a control unit, from the test result register, for evaluating the nozzle condition.

摘要： There is disclosed an ink jet printhead which comprises a plurality of nozzles (3) and one or more heater elements (10) corresponding to each nozzle. Each heater element is configured to heat a bubble (12) forming liquid in the printhead to a temperature above its boiling point to form a gas bubble therein. The generation of the bubble causes the ejection of a drop (16) of an ejectable liquid (such as ink) through respective corresponding nozzle, to effect printing. Each heater element is in the form of a beam suspended over at least a portion of the bubble forming liquid so as to be in thermal contact therewith. This configuration of printhead provides for a relatively high efficiency of operation.
