Abstract:
1. A fluid ejecting device comprising: a substrate having a first surface and a second surface located opposite the first surface; a nozzle plate formed over the first surface of the substrate, the nozzle plate having a nozzle through which fluid is ejected, the nozzle having a center axis; a drop forming mechanism situated at the periphery of the nozzle; a fluid chamber in fluid communication with the nozzle, the fluid chamber having a first wall and a second wall, the first wall and the second wall being positioned at an angle relative to each other; a fluid delivery channel formed in the substrate extending from the second surface of the substrate to the fluid chamber, the fluid delivery channel being in fluid communication with the fluid chamber, the fluid delivery channel having a center axis; and a source of fluid impedance comprising a physical structure located between the nozzle and the fluid delivery channel, wherein the fluid delivery channel is substantially perpendicular to the first and second surfaces of the substrate and the center axis of the fluid delivery channel is offset from the center axis of the nozzle.
