摘要： A method of dispensing liquid drops includes providing a liquid dispenser array structure. Liquid dispensers, located on a common substrate, include a liquid supply channel and a drop formation device associated with an interface of a liquid dispensing channel and the liquid supply channel. A carrier liquid is provided by a first liquid supply that flows continuously through an outlet of the liquid dispensing channel during a drop dispensing operation. A functional liquid, immiscible in the carrier liquid, is provided by a second liquid supply to the liquid dispensing channel through the liquid supply channel. The drop formation device is selectively actuated to form a discrete drop of the functional liquid in the carrier liquid flowing through the liquid dispensing channel. The flowing carrier liquid causes the discrete drops of the functional liquid to move through the outlet of the liquid dispensing channel during the drop dispensing operation.

摘要： Drop formation devices are provided with a sequence of drop formation waveforms to modulate the liquid jets to selectively cause portions of the liquid jets to break off into print drops having a print drop volume Vp and non-print drops having a non-print drop volume Vnp. The print and non-print drop volumes are distinct from each other. A timing delay device shifts the timing of drop formation waveforms supplied to drop formation devices of first and second nozzle groups so that print drops from the first and second nozzle groups are not aligned relative to each other. A charging device includes a charge electrode that is positioned in the vicinity of break off of liquid jets to produce a print drop charge state on drops of volume Vp and to produce a non-print drop charge state on drops of volume Vnp.

摘要： Drop formation devices are provided with drop formation waveforms to modulate liquid jets to cause portions of the liquid jets to form print drops having a jet breakoff length Lp in a print drop breakoff length range Rp and non-print drops having a jet breakoff length Lnp in a non-print drop breakoff length range Rnp. A timing delay device shifts the timing of the waveforms supplied to drop formation devices of first and second nozzle groups so that print drops formed from first and second nozzle groups are not aligned relative to each other. A charging device includes a charge electrode that is positioned relative to the breakoff length Lp and breakoff length Lnp such that there is a difference in electric field strength at the two breakoff lengths to produce a print drop charge state on print drops and a non-print drop charge state on non-print drops.

摘要： Methods and systems are described herein for driving droplet ejection devices with multi-level waveforms. In one embodiment, a method for driving droplet ejection devices includes applying a multi-level waveform to the droplet ejection devices. The multi-level waveform includes a first section having at least one compensating edge and a second section having at least one drive pulse. The compensating edge has a compensating effect on systematic variation in droplet velocity or droplet mass across the droplet ejection devices. In another embodiment, the compensating edge has a compensating effect on cross-talk between the droplet ejection devices.

摘要： A method of producing a print on a recording medium includes receiving positive and negative image data for the print to be produced. A selected region of the recording medium is discharged. First-sign charged fluid is deposited in a selected first-sign charged-fluid pattern on the selected region of the recording medium, the first-sign charged-fluid pattern corresponding to the positive image data. Second-sign charged fluid is deposited in a selected second-sign charged-fluid pattern on the selected region of the recording medium, the second-sign charged-fluid pattern corresponding to the negative image data and the second sign being different from the first, sign. Charged dry ink having charge of the second sign is deposited onto the recording medium. The deposited dry ink is attracted to the first-sign charged-fluid pattern and adheres to the recording medium in the first-sign charged-fluid pattern.

摘要： Fabricating a printhead includes providing a silicon wafer including first and second surfaces and a nozzle membrane layer on the first surface of the silicon wafer. The silicon wafer is sized to a thickness ranging from 10 to 250 microns. A plurality of chambers is defined on the second surface of the silicon wafer by depositing and patterning a mask on the second surface of the silicon wafer. The plurality of chambers is formed in the silicon wafer by etching portions of the silicon wafer that are exposed by the mask. A second wafer, permanently bonded to the second surface of the silicon wafer, includes a material property that is compatible with a material property of the silicon wafer. A preformed fluid channel of the second wafer is in fluid communication with the plurality of chambers of the silicon wafer after permanent bonding of the wafers.
