PRINTHEAD SYSTEM WITH SUBSTRATE CHANNEL SUPPORTING PRINTHEAD AND INK HOSE

摘要

A printhead system for an inkjet printer includes a pagewidth inkjet printhead formed from a plurality of printhead integrated circuits arranged end-to-end; a flexible ink hose extending a length of the printhead, the flexible ink hose defining a plurality of distinct and parallel ink channels and further defining plural groups of apertures repeated along the length of the flexible ink hose; and a substrate channel supporting on a top thereof the plurality of printhead integrated circuits and supporting from a bottom thereof the extruded flexible ink hose, the substrate channel provided with plural groups of repeated apertures defined therethrough and extending along a length of the channel. Each group of apertures provided on the substrate channel aligns with a respective group of apertures defined along the flexible ink hose and further with apertures provided on a bottom of one printhead integrated circuit.
