摘要： A printhead includes a nozzle plate, a filter, and a plurality of walls. Portions of the nozzle plate define a plurality of nozzles. The filter, for example, a filter membrane, includes a plurality of pores grouped in a plurality of pore clusters. Each of the plurality of walls extends from the nozzle plate to the filter membrane to define a plurality of liquid chambers positioned between the nozzle plate and the filter membrane. Each liquid chamber of the plurality of liquid chambers is in fluid communication with a respective one of the plurality of nozzles. Each liquid chamber of the plurality of liquid chambers is in fluid communication with the plurality of pores of a respective one of the plurality of pore clusters. The respective one of the plurality of pore clusters includes two pore sub-clusters spaced apart from each other by a non-porous portion of the filter membrane.

摘要： A group timing delay device is provided to shift the timing of drop formation waveforms supplied to drop formation devices of nozzles of one of first and second groups so that print drops formed from nozzles of the first and second groups are not aligned relative to each other along a nozzle array direction. A charging device includes a common charge electrode associated with liquid jets formed from the nozzles of the first and second group and a source of varying electrical potential between the charge electrode and liquid jets. The source of varying electrical potential provides a charging waveform that is independent of print and non-print drop patterns. The charging device is synchronized with the drop formation device and the group timing delay device to produce a print drop charge state on print drops and a non-print drop charge state on non-print drops.

摘要： A compressed fluid microvalve for controlling flow of compressed fluid from a region of high pressure to a region of low pressure is provided. A chamber includes an inlet port, a region of high pressure, and an outlet port leading to a region of low pressure. A cantilever beam includes a first portion, a second portion, and a third portion. The cantilever beam is anchored to a portion of the chamber and is suspended in the chamber such that the first portion and third portion of the cantilever beam are exposed to the region of high pressure on all sides. The second portion of the cantilever beam overlaps the outlet port. The cantilever beam includes a first position in contact with the outlet port to prevent fluid flow from the chamber through the outlet port and a second position removed from contact with the outlet port to permit fluid flow from the chamber through the outlet port. A controller is in electrical communication with the cantilever beam and is configured to provide an actuation pulse to the cantilever beam to move the cantilever beam from the first position in contact with the outlet port to the second position removed from contact with the outlet port.

摘要： A micro-electromechanical device for controlling compressed fluid flow is provided. A chamber includes a fluid flow inlet port, a high pressure region exceeding 30 bar, and a fluid flow outlet port. A moveable micro-electromechanical valve is positioned to contact the fluid flow outlet port when the moveable micro-electromechanical valve is in a first position. An electrical connection to the moveable micro-electromechanical valve provides an electrical pulse train to the moveable micro-electromechanical valve to actuate the valve at a rate of 10 KHz or more to move the valve in order to control fluid communication between the high pressure region and a low pressure region downstream from the fluid flow outlet port.

摘要： A method is used to make a laser-ablatable element for direct laser engraving that has a laser-ablatable, relief-forming layer that has a relief-image forming surface and a bottom surface. The relief-forming layer can be prepared by applying multiple formulations. Each formulation comprises a coating solvent, a laser-ablatable polymeric binder, and an infrared radiation absorbing compound. The infrared radiation absorbing compound concentration in the resulting sub-layers is different in each adjacent pair of sub-layers so that the concentration is always greater in each pair sub-layer that is closer to the substrate, and the concentration is progressively greater in the sub-layers as they are closer to the substrate after the coating solvent is removed, wherein the multiple sub-layers provide a relief-forming layer so that the sub-layer farthest from the substrate provides a relief-image forming surface.
