    摘要： A printhead includes at least a first drop generator set and at least a second drop generator set. The first drop generator set includes a first type of drop generator, whereas the other drop generator sets include a second type of drop generator. The first and second types of drop generators are primarily different with regard to the drop weights they are capable of providing. Preferably, the first type of drop generator comprises a multi-nozzle configuration, whereas the second type comprises single nozzle configurations. In one embodiment, a first type of ink is ejected by the first type of drop generators and a second type of ink is ejected by the second type of drop generators. To prevent unwanted mixing of the black and color inks, a first orifice or nozzle layer is provided separate and apart from a second orifice layer. In this manner, a single printhead may be used for the delivery of both black and color inks.

    摘要： A porous foam based ink containment system is provided with grooves defined in the exterior portion thereof, for storing ink, while preventing ink leakage from the ink-jet pen. The grooves provide passageways to allow air diffused throughout the ink and trapped air bubbles within the foam to expand and move to the atmosphere. An atmospheric vent is in fluid communication with at least one of the grooves.

    摘要： A variable optical density print system and method for continuous variation of the optical density among successive droplets expelled from the same nozzle, the print system comprising a fluid channel connected to a basis fluid supply and a fluid channel connected to a colorant concentrate fluid supply. Each fluid channel is in fluid communication with a single ink firing chamber. Appropriate amounts of basis fluid and colorant concentrate fluid are delivered to the firing chamber by briefly opening a microvalve positioned within each fluid channel. The fluids mix in the firing chamber and are then ejected as a single ink droplet which possesses a desired optical density.

    摘要： A method of fabricating a fluid ejector is disclosed. In the present embodiment, a plurality of thin film layers are deposited on a first surface of a printhead substrate, the plurality of thin film layers form a thin film membrane. At least one of the layers forms a plurality of fluid ejection elements, and at least another of the layers forms a plurality of conductive leads to the fluid ejection elements. A plurality of fluid feed holes are formed in the thin film membrane. At least one opening in a second surface of the substrate is formed, the opening providing a fluid path from a second surface of the substrate through the substrate. The plurality of fluid feed holes are located over the at least one opening in the substrate, and all portions of the fluid ejection elements and conductive leads overlie the substrate.
