摘要： In the embodiments of the simplified ink jet head described in the specification an orifice plate has specially profiled orifice openings to assure axial projection of drops when ink is supplied from an asymmetric ink path leading to the orifice. For this purpose the orifice includes cylindrical ink inlet and outlet portions with the ink outlet portion having a smaller diameter and a shorter length than the inlet portion and a tapered conical portion joining the ink inlet portion and the ink outlet portion. Preferably, the diameter of the inlet portion is no more than about twice the diameter of the outlet portion.

摘要： A fluid ejection apparatus includes a fluid distribution layer between a fluid manifold and a substrate. The fluid distribution layer includes fluid supply channels and fluid return channels. Each fluid supply channel receives fluid from the fluid supply chamber and circulates a fraction of the received fluid back to the fluid return chamber through a return-side bypass. The substrate include a plurality of flow paths, each flow path includes a nozzle for ejecting fluid droplets. Each flow path receives fluid from a respective fluid supply channel, and channel un-ejected fluid into a respective fluid return channel. Each fluid return channel can collect the un-ejected fluid from one or more flow paths and a supply-side bypass, and return the collected fluid back to the fluid supply chamber.

摘要： Techniques are provided for forming nozzles in a microelectromechanical device. The nozzles are formed in a layer prior to the layer being bonded onto another portion of the device. Forming the nozzles in the layer prior to bonding enables forming nozzles that have a desired depth and a desired geometry. Selecting a particular geometry for the nozzles can reduce the resistance to ink flow as well as improve the uniformity of the nozzles across the microelectromechanical device.

摘要： A fluid ejection apparatus includes a printhead having a substrate. The substrate includes a nozzle face having a width direction and a length direction. The nozzle face includes a set of four columns of nozzles oriented in a column direction substantially along the width direction of the nozzle face, and the nozzles in each column are positioned on a straight line along the column. A spacing between two adjacent columns of the four adjacent columns is different than a spacing between another two adjacent columns of the four adjacent columns. In some implementations, a controller can control timing of ejection of fluid droplets from the nozzles to deposit lines of fluid droplets on a medium, and the medium can travel relative to the nozzle face.
