摘要:
A multi-color ink tank is adapted to replace individual different color ink tanks in a cavity of a given support structure. Elements on the body of the multi-color ink tank have configurations enabling compatibility with the support structure. The elements include empty opposite side portions of the body defining laterally spaced apart bottom openings that adapt the opposite side portions to seat in spaced slots in the cavity over keys therein and an intermediate central recessed region defined between the opposite side portions that adapts the body to straddle an intermediate slot between the spaced slots and a key therein and also straddle partitions in the cavity forming the slots. The elements also include tabs blocking some latches used to releasably lock some individual ink tanks to thereby identify the latch to be used to releasably lock the multi-color ink tank.

A multi-color ink tank includes certain features that properly interface with features on a printhead and carrier support structure to operatively seat the ink tank in the carrier support structure in a sealed flow communicative relationship with the printhead. These interface features are spaced apart relative to one another at distances (or dimensions) that ensure the desired seating and sealing of the ink tank in the carrier support structure and thereby the reliable supply of ink for operation of the inkjet printing system.

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.

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.
