摘要： This present invention is embodied in a printing system with thermally efficient heat transfer capabilities for reducing dimpling of a nozzle member during fabrication of the printhead portion of an inkjet printer. The printing system of the present invention includes a printhead assembly and an ink supply for printing ink on print media. The printhead assembly includes a printhead body having a heat transfer device, ink channels and a nozzle member having plural nozzles coupled to respective ink channels. The nozzle member is secured to the printhead body with a suitable adhesive layer. The heat transfer device can be defined by a portion of or the entire printhead body for reducing thermal expansion of the printhead body during exposure to heat. Namely, the heat transfer device of the printing system of the present invention is capable of efficiently reducing thermal expansion of the printhead body during the process of adhering (which includes heating and curing the adhesive) the nozzle member to the printhead body. As a result, trajectory errors of ejected ink droplets from the nozzles are reduced.

摘要： This present invention is embodied in a printing system and method for inducing shrinkage-tensioning of a flexible nozzle member of a printhead portion of an inkjet printer with an adhesive and novel arrangement. The printing system of the present invention includes a nozzle member securely coupled to a printhead body with an adhesive arrangement that allows shrinkage-induce tensioning of the nozzle member. The adhesive arrangement includes having an adhesive located between a top portion of the printhead body and the flexible nozzle member. The top portion has a mechanical structure such that it induces tensioning of the flexible nozzle member during thermal expansion of the adhesive. Namely, the adhesive arrangement of the printing system of the present invention is capable of efficiently tensioning, and thus, flattening the flexible nozzle member during the adhesion process of the nozzle member. As a result, trajectory errors of ejected ink droplets from the nozzles are reduced.

摘要： For each totally black pixel of image data to be printed using a fluid-ejection printing device, it is determined whether the pixel is part of a line feature or an area fill feature of the image data. Where the pixel is part of a line feature, a first printing mask selected that is optimized for printing line features. Where the pixel is part of an area fill feature, a second printing mask is selected that is optimized for printing area fill features. Each mask specifies a number of fluid droplets to be printed and positions where the fluid droplets are to be printed. The selected mask is applied to the pixel. The pixel is printed using the mask that has been applied. The fluid-ejection printing device prints the pixel by ejecting the number of fluid droplets specified by the mask at the positions specified by the mask.

摘要： The present invention overcomes the problem of filter blockage created by bubble accumulation underneath the filter of previous printheads with a filter carrier and filter that reduces air bubble blockage of the filter. Namely, air bubble blockage of the filter is avoided by trapping more bubbles in a designated area with a horizontal ink flow, relative to the substrate. In addition to the filter carrier and filter, the printing device further includes an outer housing, a substrate and an ink conduit. The substrate has a back surface and a front surface with ink ejection chambers formed thereon. The ink conduit has a distal end proximate to the back surface of the substrate. The ink conduit, the outer housing and the substrate define an ink flow path to the ink ejection chambers and a bubble accumulation chamber in communication with the ink flow path such that buoyancy will tend to move bubbles that accumulate in the ink flow path into the bubble accumulation chamber.

摘要： Described herein is a snout insert, referred to as an exapander, which is pressed fit into the snout of a plastic inkjet print cartridge. The expander has a low coefficient of thermal expansion (CTE) and a high tensile modulus relative to the print cartridge body. The expander reduces the CTE of the snout to be closer to, or less than, the CTE of the nozzle member, such as a TAB head assembly, to reduce or prevent warpage of the nozzle member due to thermal cycling of the print cartridge during the manufacturing process. The nozzle member is then fixed to the snout. The expander is designed for a precise fit into the snout and, in one embodiment, includes machinable datums to ensure a tight fit. In one embodiment, the expander is inserted through the ink reservoir area in the print cartridge body and pushed into the snout.
