摘要： A method of ejecting liquid includes providing a liquid dispenser including a substrate and a diverter member. Portions of the substrate define a liquid supply channel and a liquid return channel. The diverter member includes a MEMS transducing member positioned in contact with a compliant membrane. The compliant membrane is anchored to the substrate such that the compliant membrane forms a portion of a wall of the liquid dispensing channel. 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 when drop ejection is desired.

摘要： A continuous liquid ejection system includes a liquid chamber in fluidic communication with a nozzle. The liquid chamber contains liquid under pressure sufficient to eject a liquid jet through the nozzle. A drop formation device is associated with the liquid jet. The drop forming device is actuatable to produce a modulation in the liquid jet to selectively cause portions of the liquid jet to break off into one or more pairs of drops traveling along a path. Each drop pair is separated on average by a drop pair period. Each drop pair includes a first drop and a second drop. The drop formation device is also actuatable to produce a modulation in the liquid jet to selectively cause portions of the liquid jet to break of into one or more third drops traveling along the path separated on average by the same drop pair period. The third drop is larger than the first drop and the second drop. A charging device 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 period of formation of the drop pairs or the third drops, the drop pair period. The waveform also includes a first distinct voltage state and a second distinct voltage state. The charging device and the drop formation device are synchronized to produce a first charge to mass ratio on the first drop of the drop pair, a second charge to mass ratio on the second drop of the drop pair, and a third charge to mass ratio on the third drop. The third charge to mass ratio is substantially the same as the first charge to mass ratio. A deflection device causes the first drop of the drop pair having the first charge to mass ratio to travel along a first path, and causes the second drop of the drop pair having the second charge to mass ratio to travel along a second path, and causes the third drop having a third charge to mass ratio to travel along a third path. The third path is substantially the same as the first path.

摘要： A liquid dispenser includes a substrate. A first portion of the substrate defines a liquid dispensing channel including an outlet opening. A second portion of the substrate defines a liquid supply channel and a liquid return channel. A liquid supply provides a continuous flow of liquid from the liquid supply through the liquid supply channel through the liquid dispensing channel through the liquid return channel and back to the liquid supply. A diverter member, positioned on a wall of the liquid dispensing channel that includes the outlet opening, is selectively actuatable to divert a portion of the liquid flowing through the liquid dispensing channel through outlet opening of the liquid dispensing channel. The diverter member includes a MEMS transducing member. 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 continuous flow of liquid through 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.

摘要： A continuous inkjet printhead includes a jetting module, a fluid system, and a controller. The jetting module includes an array of nozzles. The fluid system includes a liquid source and a pressure control device. The liquid source includes a liquid and is connected in fluid communication with the jetting module. The controller is in electrical communication with the pressure control device of the fluid system and is configured to provide a first signal to the pressure control device to cause the liquid to be ejected as liquid streams through the nozzles of the array at a first pressure sufficient to create a stream of print-selectable drops. The controller is configured to provide a second signal to the pressure control device to cause the liquid to be ejected as liquid streams through the nozzles of the array at a second pressure with the second pressure being less than the first pressure. The controller is configured to provide the first signal to the pressure control device after a period of time.

摘要： A connector includes a structure for receiving the tubing and a mechanism for releasably retaining the tubing over the tubing receiving structure. The structure for receiving the tubing includes an exterior surface with portions of the exterior surface of the structure defining a tapered section and at least one ring. The mechanism for releasably retaining the tubing over the tubing receiving structure is releasably engagable with the tubing receiving structure. Portions of the mechanism define a longitudinal bore through which the tubing can be inserted. The mechanism includes an interior surface with portions of the interior surface defining a tapered section. When the tubing is positioned over the tapered section and the at least one ring of the tubing receiving structure and the tubing receiving structure is engaged with the retaining mechanism, at least two fluid seals are created or present. A first fluid seal is present between the tapered section of the tubing receiving structure, the tubing, and the tapered section of the retaining mechanism. A second fluid seal is present between the tubing and the at least one ring of the tubing receiving structure.

摘要： A system for flushing ink residue from a fluid system is provided for use with a continuous ink jet print station. Ink is rapidly drained from the fluid system, and the fluid system is refilled with a flush fluid. The flow of flush fluid is directed through all fluid system components which normally contain ink. Subsequently, the flow of flush fluid can be diverted to a waste tank rather than re-circulated into the ink tank.
