    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.

    摘要翻译： 墨水输送系统通过在打印头中的墨水排出机构周围设置两个或更多个墨水室来实现平衡的墨水流动。 多个饼形墨水室可以布置在喷墨机构上方的圆圈中，其从每个墨水室提供短的墨水路径，以及具有大致相同长度的墨水路径。 这促进了墨水流量和墨水供应的相同的压降/损失，从而改善了对打印头的墨水供给，并提供了改进的喷射效率和打印头性能。

    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.
