摘要： Methods and systems of ejecting ink drops from an inkjet printer are disclosed. The methods and systems can include a printhead with one or more stepped nozzles each with an associated entrance diameter and exit diameter. Ink can be received into the printhead and formed into ink drops in the stepped nozzles. The ink drops can each have an associated drop mass and drop speed. The stepped nozzles can be provided such that the exit diameter can independently dictate the drop mass and the entrance diameter can independently dictate the drop speed. As such, the complexity of jet design optimization is reduced.

摘要： Methods and apparatus for performing addressable fusing and/or heating of a substrate undergoing xerographic processing are disclosed. The apparatus includes a fuser having an array of addressable heating elements in radiative communication with a substrate through a fuser roll or fuser belt. The array of addressable heating elements is operated to selectively heat portions of the substrate to achieve a desired effect on the substrate, such as changing its surface finish, or fusing unfused toner to the substrate. In the case of toner fusing, the array is operated such that substantially only an area covered by the unfused toner is heated. This eliminates the need for blanket fusing, and generally provides for greater flexibility in xerographically processing substrates. Apparatus and methods for performing two-sided selective fusing and/or heating are also disclosed.

摘要： A method of making a laser ablated article includes forming an article of one or more layers, each of which absorbs radiation within the wavelength range of from about 210 nm to about 360 nm and at least one of which is a hydrophobic fluorine-containing graft copolymer derived from at least one fluorine-containing monomer and at least one comonomer containing at least one aromatic group, and processing the article with a laser that outputs radiation at a wavelength of between about 210 nm and about 360 nm. The graft copolymer is surprisingly absorptive to radiation within the specified wavelength range. Articles formed using laser ablation include a nozzle plate of an ink jet printhead, wherein the nozzle plate contains ink jet openings formed by laser ablation and has a polymer substrate coated with the laser ablatable hydrophobic fluorine-containing graft copolymer.

摘要： The present invention is a multispot laser light source assembled from at least two individual laser diodes in accordance with a design model. The multispot laser includes at least two semiconductor laser diodes, both of which are permanently affixed to a chip carrier. The chip carrier rigidly supports the diodes and conducts heat away from the the diodes to be dissipated by a heat sink. The present invention is further characterized by a predefined relationship between the chip carrier material, the relative dimensions of the chip carrier, and the separation distance of the diodes from the heatsink, which results in significant reduction in the thermal droop and crosstalk between the diodes.
