Abstract
An inkjet printhead includes: a rigid elongate manifold having at least one ink supply channel and a lower surface with a longitudinal ink cavity defined therein, the longitudinal ink cavity having a roof and sidewalls extending between the roof and the lower surface; a metal film sealingly attached to the lower surface so as to bridge across the longitudinal ink cavity, the film having a plurality of film apertures for receiving ink from the longitudinal ink cavity; and a plurality of printhead chips attached to the film, each printhead chip receiving ink from the longitudinal ink cavity via the film apertures. A plurality of through-holes are defined in the manifold to provide fluid communication between the ink supply channel and the longitudinal ink cavity. The through-holes extend perpendicular to the ink supply channel and the longitudinal ink cavity.
