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 and is actuatable to produce a modulation in the liquid jet that cause portions of the liquid jet to break off into a series of drop pairs traveling along a path. Each drop pair is separated in time on average by a drop pair period. Each drop pair includes a first drop and a 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 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 drop velocity modulation device varies a relative velocity of a first drop and a second drop of a selected drop pair 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 causes the first drop having the first charge state to travel along a first path, causes the second drop having the second charge state to travel along a second path, and causes the combined drop having the third charge state to travel along a third 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 an outer boundary of a cavity. Other portions of the substrate define 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 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 substrate. A second portion of the MEMS transducing member extends over at least a portion of the cavity and is free to move relative to the cavity. A compliant membrane is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member. A second portion of the compliant membrane is anchored to the substrate such that the compliant membrane forms a portion of a wall of the liquid dispensing channel. The wall is positioned opposite the outlet opening.

摘要： Reducing waste in a digital printing system (200) includes moving media (214) through a web transport system (205) at a first speed. A first job is printed on the print media and a downstream finishing device (203) in a first configuration acts on the media. The web slows to a second speed prior the end of the first job and the finishing device changes to a second configuration after the first job has passed. A time to complete changing from the first to the second configuration is estimated and a time for a first section of the media containing the end of the first job to arrive at the finishing device is estimated. A second job is printed on the media prior to completion of the change based on the estimated time to completion.

摘要： An apparatus and method of ejecting liquid drops includes modulating a liquid jet to cause it to break off into drop clusters, including first and second drops traveling along a path, separated on average by a drop cluster period. An input image data independent charging waveform of a charging device includes a period that is equal to the cluster period and first and second voltage states having opposing polarities. The charging device produces first and second charge states on the first and second drops, respectively, of each cluster. The first and second drops are deflected away from the path toward first and second catchers, respectively. Relative velocity of drops of a selected drop cluster is modulated in response to input print data causing the drops to form a merged drop traveling along the path having a third charge state that prevents it from being deflected to either catcher.
