Printhead chip having longitudinal ink supply channels

摘要

A pagewidth inkjet printhead is provided. The printhead comprises: (a) a plurality of nozzles formed on a frontside of a substrate, each nozzle having a respective nozzle inlet; and (b) a plurality of ink supply channels. Each ink supply channel is configured for supplying ink from a backside of the substrate to a corresponding group of nozzle inlets. Further, each ink supply channel is dimensioned for receiving ink from one or more outlets in a molded ink manifold. Relatively wide ink supply channels allow the printhead to be directly bonded to a molded ink manifold, facilitating alignment and avoiding leaks.
