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 one or more printhead chips attached to the base, each printhead chip receiving printing fluid from a plurality of the fluid outlets, wherein all fluid outlets are laterally flared towards a side of a respective printhead chip. 2. The inkjet printhead of claim 1 , wherein the based comprises a truss structure having a plurality of webs contiguously defined by a wavelike structure. 3. The inkjet printhead of claim 1 , wherein the fluid outlets are generally triangular or bell-shaped. 4. The inkjet printhead of claim 1 , wherein a plurality of butting printhead chips are arranged in a row along the fluid manifold. 5. The inkjet printhead of claim 1 , wherein the printhead chips are attached to the base via an adhesive film. 6. The inkjet printhead of claim 1 , wherein the fluid outlets extend laterally beyond at least one edge of each printhead chip. 7. The inkjet printhead of claim 1 , wherein the fluid manifold is comprised of a molded polymer material. 8. The inkjet printhead of claim 1 , wherein each fluid outlet is flared towards a respective bubble-venting cavity. 9. The inkjet printhead of claim 8 , wherein each bubble-venting cavity is positioned beyond an edge of a respective printhead chip. 10. The inkjet printhead of claim 9 , wherein each bubble-venting cavity has a floor defined by a shelf stepped from a respective fluid outlet. 11. The inkjet printhead of claim 10 , wherein the floor is curved downwards towards the respective fluid outlet. 12. The inkjet printhead of claim 1 , wherein the fluid outlets are alternately flared towards opposite longitudinal sides of the printhead chips.
