摘要： A system and method to provide pressure to de-prime a printhead. An image forming device comprises an ink reservoir that contains ink and provides the ink to a printhead. When a fault condition is detected that indicates a likelihood of a solidifying of the ink, the printhead is de-primed by applying pressure to the printhead to purge the ink from the printhead. The fault condition comprises any of a loss of power, a power-down process, or a printhead temperature being less than or equal to a threshold temperature.

摘要： Systems and methods of ejecting ink drops from an inkjet printer are disclosed. The systems and methods can include a printhead with one or more actuators with associated nozzles and membranes A voltage waveform can be applied to the actuators to fill the actuators with a volume of ink and eject the ink through the nozzles as ink drops. The voltage waveform can have associated pre-fill voltage to fill the actuator with ink and a firing voltage to eject the ink. The actuator membranes can have multi-height dimples to protect the membranes from contacting electrodes and reduce the electric field.

摘要： A structure and method including a filter assembly, wherein the structure can be an ink jet printhead including the filter assembly. The filter assembly can include a first filter layer having a plurality of pores therein, wherein the pores have a first pitch, and a second filter layer having a plurality of pores therein, wherein the pores in the second filter layer have a second pitch which is different than the first pitch. The structure can include a fluid path through the filter assembly. An area of overlap of the pores in the first filter layer with the pores in the second filter layer, in a vertical direction perpendicular to a plane of the filter assembly, can include a periodicity.

摘要： A chip used for dispensing a fluid such as ink provides ink-dispensing ejectors having an ink cavity over a supporting substrate, and further provides a heater for heating the ink in the cavity. The heater can be interposed between the substrate and the ink cavity to provide direct heating of ink as it is being dispensed. Various embodiments further comprise the use of the heater structure as a temperature probe to measure the temperature of the ink in the ink cavity. Other embodiments provides a chip having both a temperature probe and a heater as separate structures interposed between the ink cavity and the substrate. Further described is a temperature probe and/or heater which traverses a majority of a width of a substrate, and surrounds each drop ejector on at least two sides.
