First claim

Opening claim text (preview).

The invention claimed is: 1. An inkjet printhead comprising: an elongate fluid manifold having a base comprising a plurality of fluid delivery compartments, each compartment having a fluid outlet and a bubble-venting cavity; and one or more printhead chips attached to the base, each printhead chip receiving printing fluid from one or more fluid outlets, wherein each fluid outlet is aligned with a respective printhead chip and each bubble-venting cavity is offset from the respective printhead chip. 2. The inkjet printhead of claim 1 , wherein each fluid outlet is configured for moving bubbles towards the bubble-venting cavity. 3. The inkjet printhead of claim 2 , wherein each fluid outlet is flared towards the bubble-venting cavity. 4. The inkjet printhead of claim 1 , wherein each fluid delivery compartment comprises a shelf defining a floor for the bubble-venting cavity. 5. The inkjet printhead of claim 4 , wherein the shelf has an edge curved towards the fluid outlet. 6. The inkjet printhead of claim 1 , wherein one or more fluid supply channels of the printhead chip are aligned with each fluid outlet. 7. The inkjet printhead of claim 1 , wherein the fluid outlets are alternately flared towards opposite longitudinal edges of the printhead chips.
