摘要： A continuous inkjet system includes a plurality of nozzles producing a respective liquid jet through each nozzle. A stimulation device (42) at each nozzle is responsive to different types of stimulation signals to produce a modulation in the respective liquid jet to selectively control droplet break off relative to phases of the cycle of a varying voltage source (51) that is connected to a charge electrode (44). The break off phase of a droplet relative to the voltage phase of the voltage source will determine whether the droplet is charged or not charged. Droplets that become charged may be deflected from their paths and a deflection mechanism including the charge electrode determines which droplets are allowed to reach a surface for say printing and which droplets are collected and not deposited upon the surface.

摘要： A printhead includes a liquid manifold. A filter is in fluid communication with the liquid manifold. A nozzle plate includes a length and an array of nozzles extending along the length of the nozzle plate. A liquid chamber is positioned between the nozzle plate and the filter. The liquid chamber is in fluid communication with the array of nozzles and the filter and includes a width that is substantially perpendicular to the length of the nozzle plate. The liquid chamber includes a structure that is spaced apart from the nozzle plate and spaced apart from the filter. The structure spans the width of the liquid chamber. A liquid source provides a liquid through the manifold, the filter, the liquid chamber under pressure sufficient to jet individual streams of the liquid from the array of nozzles.

摘要： Satellite droplets (9,10,11) that have a lifetime selectable between an infinite lifetime and a finite lifetime are formed with a continuous fluid-jet system having a drop generator, a stimulation device (2), and a nozzle plate (3) with at least one nozzle opening. A force is applied to eject a fluid jet having a diameter D from the nozzle openings and an adjustable energy drive pulse is applied to the stimulation device in a manner to create a series of perturbations on the ejected fluid jet, such that the perturbations are separated by a distance lambda. The drive pulse is defined by a pulse shape, a pulse amplitude, and a pulse duty cycle. A first satellite formation state is established by adjusting the energy of the of drive pulse (12) while operating the continuous fluid-jet system in a state wherein the lambda/D values are greater than theta and correspond to the measured normalized Rayleigh growth rate within or beyond the first minimum. The drive pulse (13) is adjusted in a manner to bring about a second satellite formation state after at least 1 lambda of the first satellite formation state.

摘要： A drop generator is operated to form large-volume and small-volume droplets by providing a droplet generator having a nozzle and an adjustable stimulation device; supplying liquid to the droplet generator such that a stream of diameter D emanates from the nozzle; activating the stimulation device to produce a first set of perturbations on the liquid stream, the perturbations having a period x such as to cause the liquid stream to form into small-volume droplets (26); selectively adjusting the stimulation device to produce a second set of perturbations on the liquid stream, the second set of perturbations having a period Nx such as to cause a segment of the liquid stream to form into a large-volume droplet (28), whereby the large-volume droplet is N times the volume of the small-volume droplets; and further adjusting the stimulation device to produce a third set of perturbations on the liquid stream during the period Nx.
