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.

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： An ink container is provides ink to a vented printhead, where both the ink container and the vented printhead are positioned on a moveable carriage. The ink container receives ink from an off-carriage ink supply via an ink conduit. Air is removed from the printhead and ink container via a vacuum pump, coupled to an upper portion of the ink container via an air conduit. The vacuum pump is operable to pull air from the ink container by generating negative pressure in the ink container.
