    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: Some embodiments of the invention provide a printhead having a chip feed extending between an ink reservoir and printhead nozzles, wherein the chip feed has an inlet, and outlet, and one or more projections or recesses in a transition surface of the chip feed. The transition surface and the projection or recess can be inclined with respect to the outlet of the chip feed, and in some cases can be curved to present a concave or convex shape toward the outlet of the chip feed.
