    Abstract: A printhead module includes: an ink manifold defining a plurality of ink supply channels, the ink manifold having first and second opposite faces; a plurality of print chips mounted on the first face, each print chip receiving ink from a respective ink supply channel via a set of ink outlets defined in the first face; first PCBs mounted on the first face of the ink manifold, each print chip being electrically connected to a respective first PCB; and second PCBs mounted on the second face of the ink manifold. The first and second PCBs are connected via electrical connectors extending through longitudinal slots defined in the substrate.

    Abstract: A modular inkjet printhead includes a plurality of printhead modules arranged end on end in a row. Each printhead module includes: a substrate having a plurality of longitudinal ink supply channels; a plurality of print chips mounted on a first face of the substrate, each print chip receiving ink from a respective ink supply channel; and a plurality of fingers extending longitudinally from opposite ends of each printhead module, each finger having an ink port extending away from a second face of the substrate opposite the first face, each ink port being in fluid communication with a respective ink supply channel Each ink supply channel is connected to a respective pair of ink ports at opposite ends of each printhead module and the fingers of neighboring printhead modules are interdigitated such that the ink ports of neighboring printhead modules overlap.

    Abstract: A modular inkjet printhead includes a plurality of printhead modules arranged end on end in a row. Each printhead module includes: a substrate having a plurality of parallel ink supply channels extending longitudinally along a length thereof and a plurality of parallel printhead segments. Each printhead segment extends longitudinally along a length of the substrate and has a plurality of print chips arranged end on end in a row. A plurality of fingers extend longitudinally from opposite ends of each printhead module, each finger including a portion of a respective one of the printhead segments. The fingers of neighboring printhead modules are interdigitated such that printhead segments of neighboring printhead modules overlap.

    Abstract: An inkjet printing system includes: (a) an inkjet printhead having a rigid elongate manifold with first and second parallel ink supply channels extending along a length of the manifold between respective ink ports positioned at opposite ends thereof; and a plurality of printhead chips mounted to a lower surface of the manifold, the ink supply channels supplying ink to the printhead chips via ink outlets defined in the lower surface. One end of the manifold has a first ink inlet port for the first ink supply channel and an ink outlet port for the second ink supply channel. The other end of the manifold has a first ink outlet port for the first ink supply channel and a second ink inlet port for the second ink supply channel. An ink delivery system is configured to flow ink along the first and second channels in opposite directions.
