    摘要： Apparatus including a plurality of droplet ejection devices, an electric source and a controller. Each droplet ejection device includes a fluid chamber having an ejection nozzle, an electrically actuated displacement device associated with the chamber, and a switch having an input connected to the electric source, an output connected to the electrically actuated displacement device, and a control signal input that is controlled by the controller to control whether the input (and thus the electric source) is connected to the output (and thus the electrically actuated device). The electrically actuated displacement device moves between a displaced position and an undisplaced position to change the volume of the chamber as a capacitance associated with the electrically actuated displacement device changes in charge between an actuated condition and an unactuated condition. The controller provides respective charge control signals to respective control signal inputs to control the extent of change in charge on respective capacitances by the time that the respective switch connects the electrical signal to the respective electrically actuated displacement device.

    摘要： A single-pass print head has multiple orifice plates each serving some but not all of the area to be printed. In embodiments, the printhead includes an array of ink jet outlets sufficient to cover a target of a print substrate at a predetermined resolution, and orifice plates, each of the orifice plates having orifices, each of the orifice plates serving some but not all of the area to be printed. The orifices are arranged in a pattern such that adjacent parallel lines on the print medium are served by orifices that have different positions in the array along the direction of the print lines, that are separated by a distance that is at least an order of magnitude greater than the distance between adjacent orifices in a direction perpendicular to the print line direction.

    摘要： An apparatus for depositing droplets on a substrate is disclosed. The apparatus includes a support for the substrate, a droplet ejection assembly which includes a pumping chamber, a controller and a source of static pressure to maintain the total pressure in the pumping chamber above a threshold pressure level to avoid rectified diffusion type bubble growth in the pumping chamber. The droplet ejection assembly is positioned over the support for depositing the droplets on the substrate and includes, in addition to a pumping chamber, a displacement member and an orifice that ejects the droplets. The controller provides signals to the displacement member to eject drops.

    摘要： A method for driving a droplet ejection device having an actuator, including applying a primary drive pulse to the actuator to cause the droplet ejection device to eject a droplet of fluid in a jetting direction, and applying one or more secondary drive pulses to the actuator which reduce a length of the droplet in the jetting direction without substantially changing a volume of the droplet.

    摘要： A drop ejection system includes a flow regulator that can regulate the fluid flow to enhance fluid purging from the fluid ejection head and other system operations. The drop ejection system can include a drop ejection head with a plurality of nozzles, a pumping chamber, and a fluid purge unit capable of purging the fluid from the nozzles by generating a negative pressure outside of nozzles. The flow regulator can increases the flow resistance of the fluid flow to the drop ejection head when the fluid is purged out of the nozzles.
