Abstract
Official abstract text for this publication.
An inkjet printhead includes: an elongate fluid manifold having a base defining a plurality of fluid outlets; and a plurality of printhead chips attached to the base of the fluid manifold, each printhead chip receiving ink from one or more fluid outlets. Each fluid outlet extends transversely across the ink manifold and extends at least half a width of each printhead chip.
First claim
Opening claim text (preview).
The invention claimed is: 1. An inkjet printhead comprising: an elongate fluid manifold having a base defining a plurality of fluid outlets; and a plurality of printhead chips attached to the base of the fluid manifold via an adhesive film, each printhead chip receiving ink from one or more fluid outlets via corresponding openings in the adhesive film, wherein: each fluid outlet extends transversely across the ink manifold; and each fluid outlet and each corresponding opening of the adhesive film extends across at least half a width of each printhead chip. 2. The inkjet printhead of claim 1 , wherein a combined area of fluid outlets supplying ink to one printhead chip is at least half a total area of the printhead chip. 3. The inkjet printhead of claim 1 , wherein the fluid outlets are positioned longitudinally along the base of the fluid manifold, each neighboring pair of fluid outlets being separated by a support web. 4. The inkjet printhead of claim 3 , wherein the printhead chips are butted end-to-end and arranged in a row along the base of the fluid manifold. 5. The inkjet printhead of claim 3 , wherein each butting pair of printhead chips have respective butting end portions commonly supported by one of the support webs.
