摘要： A liquid ejection system ejects a liquid jet through a nozzle. A drop formation device modulates the jet causing portions to break off into drop pairs, including first and second drops, separated on average by a drop pair period, and modulates the jet to cause portions to break off into larger third drops separated on average by the same period. A charging device includes a varying electrical potential source providing a waveform including first and second distinct voltage states and a period equal to the drop formation period. The charging device and the formation device are synchronized to produce first, second, and third charge to mass ratios on the first, second, and third drops, respectively. A deflection device causes the first, second, and third drops to travel along first, second, and third paths, respectively. The first and third charge to mass ratios and paths are substantially the same.

摘要： A method of ejecting liquid drops includes providing liquid under pressure sufficient to eject a liquid jet through a nozzle of a liquid chamber. The liquid jet is modulated to cause portions of the liquid jet to break off into a series of drop pairs traveling along a path using a drop formation device. Each drop pair is separated in time on average by the drop pair period. Each drop pair includes a first drop and a second drop. A charging device is provided that includes a charge electrode associated with the liquid jet and a source of varying electrical potential between the charge electrode and the liquid jet. The source of varying electrical potential provides a waveform that includes a period that is equal to the drop pair period. The waveform also includes a first distinct voltage state and a second distinct voltage state. The charging device is synchronized with the drop formation device to produce a first charge state on the first drop and to produce a second charge state on the second drop. A relative velocity of a first drop and a second drop of a selected drop pair is varied using a drop velocity modulation device to control whether the first drop and the second drop of the selected drop pair combine with each other to form a combined drop. The combined drop has a third charge state. A deflection device is used to cause the first drop having the first charge state to travel along a first path, to cause the second drop having the second charge state to travel along a second path, and to cause the combined drop having the third charge state to travel along a third path.

A first portion of the MEMS transducing member is anchored to the wall of the liquid dispensing channel that includes the outlet opening. A second portion of the MEMS transducing member extends into a portion of the liquid dispensing channel that is adjacent to the outlet opening and is free to move relative to the outlet opening. A compliant membrane is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane separates the MEMS transducing member from the liquid dispensing channel. A second portion of the compliant membrane is anchored to the wall of the liquid dispensing channel that includes the outlet opening. A continuous flow of liquid is provided from a liquid supply through the liquid supply channel through the liquid dispensing channel through the liquid return channel and back to the liquid supply. The diverter member is selectively actuated to divert a portion of the liquid flowing through the liquid dispensing channel through outlet opening of the liquid dispensing channel.

摘要： An ink jet printing device has a drop generator for producing continuous streams of ink drops from at least one orifice and further has stimulation control electronics for maintaining desired stimulation conditions in response to a feedback from the drop generator. First and second feedback transducers measure the stimulation amplitude in the drop generator and generate feedback output signals in response to the stimulation. The feedback output signals are approximately equal in magnitude and opposite in sign to each other when the stimulation amplitude in the drop generator is a desired stimulation mode. An amplifier, whose inputs are the feedback output signals, provides an amplifier output signal to the stimulation control electronics which is the difference between the two feedback output signals.
