摘要： Liquid dispensing includes providing a downwardly inclined slide surface and a carrier liquid dispensing channel that includes an outlet opening on the slide surface. A carrier liquid source is pressurized causing carrier liquid to flow continuously through the outlet opening of the carrier liquid dispensing channel and down the slide surface. A liquid dispenser array structure is provided and includes functional liquid dispensers located on a substrate that is common to the functional liquid dispensers. The functional liquid dispensers include a functional liquid supply channel, a functional liquid source that provides functional liquid, and a drop formation device associated with an interface of the functional liquid supply channel and the slide surface. The drop formation device is selectively actuated to form discrete functional liquid drops in the carrier liquid flowing down the slide surface. The functional liquid is immiscible in the carrier liquid.

A functional liquid is provided to the liquid dispensing channel through a second liquid supply channel using a second liquid supply. A 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 functional liquid is immiscible in the carrier liquid. The drop ejection device is selectively actuated to divert the discrete drop of the functional liquid and a portion of the carrier liquid flowing through the liquid dispensing channel toward an outlet opening of the liquid dispensing channel.

摘要： A system and method of printing includes providing print and non-print drop formation waveforms to a drop formation device of a drop ejector in response to input print data to form print and non-print drops, respectively, from a liquid jet. First and second charging waveforms are provided to a charging electrode of a drop charging device when a relative motion of a receiver and the drop ejector is provided or measured at first and second speeds, respectively. The first and second charging waveforms are independent of input print data and include first and second voltage states. The drop formation device and the drop charging device are synchronized to produce print and non-print drop charge states on print and non-print drops, respectively. A deflection device causes print and non-print drops to travel along print and non-print drop paths, respectively, with the non-print drops being collected by a catcher.

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： A group timing delay device is provided to shift the timing of drop formation waveforms supplied to drop formation devices of nozzles of one of first and second groups so that print drops formed from nozzles of the first and second groups are not aligned relative to each other along a nozzle array direction. A charging device includes a common charge electrode associated with liquid jets formed from the nozzles of the first and second group and a source of varying electrical potential between the charge electrode and liquid jets. The source of varying electrical potential provides a charging waveform that is independent of print and non-print drop patterns. The charging device is synchronized with the drop formation device and the group timing delay device to produce a print drop charge state on print drops and a non-print drop charge state on non-print drops.

摘要： An apparatus for obtaining an image of a tooth having at least one light source providing incident light having a first spectral range for obtaining a reflectance image (122) from the tooth and a second spectral range for exciting a fluorescence image (120) from the tooth. A polarizing beamsplitter (18) in the path of the incident light from both sources directs light having a first polarization state toward the tooth and directs light from the tooth having a second polarization state along a return path toward a sensor (68), wherein the second polarization state is orthogonal to the first polarization state. A first lens (22) in the return path directs image-bearing light from the tooth toward the sensor (68), and obtains image data from the portion of the light having the second polarization state. A long-pass filter (15) in the return path attenuates light in the second spectral range.
