Abstract:
A fluid ink delivery system includes a receptacle positioned proximate to a plurality of inkjet ejectors, and an ink supply in fluid communication with the receptacle. Ink held in the receptacle may be withdrawn under negative pressure by a pump in the ink supply. A flow restrictor in fluid communication with the pump limits the negative pressure level applied by the pump to be less than a pressure that draws air across a porous member in the receptacle.
