摘要： A method of producing a print on a recording medium includes receiving image data for the print to be produced. A selected region of the recording medium is discharged. Charged fluid is deposited in a selected charged-fluid pattern corresponding to the image data on the selected region of the recording medium. Charged dry ink having charge of the opposite sign as the charge in the deposited charged-fluid pattern is deposited onto the recording medium. The deposited dry ink is repelled by the charged-fluid pattern and adheres to the recording medium outside the charged-fluid pattern.

摘要： Apparatus for producing a print on a recording medium includes a printhead providing drops of hydrophilic liquid. A hydrophobic drop-retention layer of an intermediate member receives the drops in cells including ion donors, forming a liquid pattern corresponding to image data. The ion donor in liquid-containing cells dissolves into ions. A transport member brings the recording medium into contact with the liquid pattern on the intermediate member. A voltage source applies a bias across the recording medium in contact with the liquid pattern to move ions to form a charge pattern corresponding to the liquid pattern on the recording medium. A development station applies charged dry ink to the recording medium bearing the charge pattern, so that a dry ink image corresponding to the image data is formed on the recording medium.

摘要： A liquid dispensing system includes a liquid dispenser array structure. A first liquid supply provides a carrier liquid that flows continuously through an outlet of a liquid dispensing channel during a drop dispensing operation. A plurality of liquid dispensers, located on a common substrate, includes a second liquid supply that provides a functional liquid, immiscible in the carrier liquid, to the liquid dispensing channel through a liquid supply channel. A drop formation device, associated with an interface of the liquid supply channel and the liquid dispensing channel, is selectively actuated to form discrete drops of the functional liquid in the carrier liquid flowing through the liquid dispensing channel. A receiver conveyance mechanism and the liquid dispenser array structure are positioned relative to each other such that the discrete drops of the functional liquid are applied to a receiver.

摘要： A method of continuously ejecting liquid includes providing a liquid ejection system that includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate includes a MEMS transducing member that extends over at least a portion of the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. The compliant membrane includes an orifice. Liquid is provided under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate by a liquid supply. A drop of liquid is caused to break off from the liquid jet by selectively actuating the MEMS transducing member which causes a portion of the compliant membrane to be displaced relative to the liquid chamber.

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 continuous liquid ejection system includes a substrate and an orifice plate affixed to the substrate. Portions of the substrate define a liquid chamber. The orifice plate 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 liquid chamber and is free to move relative to the liquid chamber. A compliant membrane is positioned in contact with the MEMS transducing member. A first portion of the compliant membrane covers the MEMS transducing member and a second portion of the compliant membrane is anchored to the substrate. The compliant membrane includes an orifice. A liquid supply provides a liquid to the liquid chamber under a pressure sufficient to eject a continuous jet of the liquid through the orifice located in the compliant membrane of the orifice plate. The MEMS transducing member is selectively actuated to cause a portion of the compliant membrane to be displaced relative to the liquid chamber to cause a drop of liquid to break off from the liquid jet.
