摘要： An inkjet printhead for printing redundantly in four colors. The printhead includes: an ink manifold having first, second, third and fourth ink reservoirs for supplying first, second, third and fourth inks, respectively; and first and second parallel printhead chips mounted on the ink manifold. The ink manifold has ink feed slots configured for supplying the first and second inks to the first printhead chip and for supplying the third and fourth inks to the second printhead chip.

摘要： A method of printing redundantly in four colors using a pagewide printhead having first and second rows of printhead chips mounted on a common ink manifold and receiving four colors of ink. The method includes the steps of: supplying first and second ink colors from the manifold to the first row of printhead chips; supplying third and fourth ink colors from the manifold to the second row of printhead chips; and printing the inks redundantly from the printhead chips.

摘要： A print module including: a cradle having a longitudinal cavity; an elongate printhead assembly positioned in the longitudinal cavity; and a supply assembly slidably movable relative to the cradle along an axis perpendicular to a longitudinal axis of the printhead assembly, the supply assembly having one or more ink couplings for fluidic connection to a printhead of the printhead assembly. The cradle includes a fixed limiter configured for abutment with a reaction plate of the printhead assembly so as to limit movement of the printhead assembly during movement of the supply assembly away from the printhead assembly.

摘要： 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.

摘要： A method of minimizing condensation on a lower surface of an inkjet printhead. The inkjet printhead has a plurality of printhead chips mounted on a manifold and a shield plate defining the lower surface. The method includes the steps of: disposing a heating layer between the manifold and the shield plate; heating the heating layer; and printing using the printhead chips, wherein heating of the heating layer minimizes condensation on the lower surface.

摘要： An inkjet printhead includes: a rigid elongate carrier having an ink supply channel and a lower surface having a plurality of printhead chips mounted thereon; a rigid PCB attached to the lower surface of the carrier, the PCB extending a length of the carrier and projecting laterally beyond a sidewall of the carrier; a lead retainer attached to the sidewall of the carrier; and a plurality of leads extending upwardly from contact pads positioned along a longitudinal edge portion of the PCB, each lead being secured to the sidewall of the carrier via the lead retainer. The PCB supplies power and data to the printhead chips via electrical connections between the PCB and the printhead chips.
