摘要： A multi-fluid body and an ejection head substrate connected in fluid flow communication with the multi-fluid body for ejecting multiple fluids therefrom. The multi-fluid body includes at least two segregated fluid chambers. Independent fluid supply paths lead from each of the fluid chambers providing fluid to multiple fluid flow paths in the ejection head substrate. The ejection head substrate is attached adjacent an ejection head area of the body. The fluid flow paths in the ejection head substrate have a flow path density of greater than about one flow paths per millimeter.

摘要： Ink delivery systems achieve balanced ink flow by positioning two or more ink chambers around ink ejection mechanisms in a printhead. A plurality of pie-shaped ink chambers may be arranged in a circle above an ink ejection mechanism, which provides short ink paths from each ink chamber, and ink paths having approximately the same length. This fosters even ink flow rates and equal pressure drop/loss of ink supplies, thereby improving ink feeds to a printhead and providing improved jetting efficiency and printhead performance.

摘要： In a system for laser welding work pieces along a collapsing weld interface, methods and apparatus include providing welding pads and/or stop projections on either or both of the work pieces to control the manner or amount of collapse. Preferably, the stop projections exist a separation distance from the weld interface while the welding pads exist at and form a portion of the weld interface. Buffers are taught between the weld interface and stop projection. The work pieces may comprise inkjet printhead lids and bodies. In another aspect, the invention teaches methods of laser welding inkjet printhead lids and bodies according to whether the inkjet printhead body embodies a mono or color ink body type and especially includes selective control of one or more laser light sources to illuminate the inkjet printhead lid in a specific pattern of light.

摘要： Some embodiments of the present invention provide an inkjet printhead comprising a housing and at least four ink reservoirs located in the housing. The housing can include an outer surface adapted to be covered by a chip in fluid communication with each of the at least four ink reservoirs. In some embodiments, the housing includes first and second ink vias positioned to fluidly couple first and second ink reservoirs to the outer surface. The first and second ink vias can each include a first end opening into the first and second ink reservoirs, respectively, and a second end opening to the outer surface. The inkjet printhead can have an orientation in which the outer surface lies in a substantially horizontal plane and in which the first ends of the first and second ink vias are positioned over the outer surface.

摘要： Multi-compartmentalized ink cartridges for ink jet printers and improved methods for making the ink cartridges. The multi-compartmentalized ink cartridge includes a molded, open-topped body having an interior cavity and a printhead surface area opposite the interior cavity. A divider wall is integrally molded with the molded body structure and disposed in the interior cavity to provide at least three segregated ink chambers. The divider wall includes a first wall section and a second wall section attached substantially perpendicular to the first wall section. At least first, second, third molded ink flow paths connect each of the at least three segregated ink chambers with the printhead surface area. The second and third ink flow paths are oriented relative to their corresponding ink chambers for molding with a mold insert tool so that the cartridge body does not require a separately attached member to close mold insert tool insertion areas in the body.
