摘要:
The present invention provides for a pressure development apparatus for an image forming device which includes a first pressure roller that has a width which is at least approximately equal to a media width of media to be developed and is adapted to apply pressure onto a surface of media to be developed. The development apparatus also includes at least a block-like member or a second roller mounted on top of the first pressure roller which is adapted to apply pressure onto the first pressure roller for the purpose of developing media to be developed. The block-like member or second pressure roller is effective to minimize any lateral deflection of the first pressure roller.

An image-forming device comprises a rotating belt that includes a plurality of micro-members. The micro-members are preferably spherical members or hook and loop members. The rotating belt having the micro-members thereon is adapted to contact microencapsulated media with a force sufficient to rupture unhardened microcapsules on the media.

The present invention relates to an image-forming device that comprises a roller that includes a plurality of micromembers. The micromembers are preferably hook or loop-like members made of a compliant material such as plastic or rubber. The micromembers on the roller essentially define a compliant surface, which is self-correcting for unintentional media thickness variations within a print area. The roller is rotational such that when the roller contacts the media the rotational or spinning force is converted to a compressional force, which is sufficient to rupture the microcapsules in the media.

A pressure development apparatus for an image forming device includes a pair of pressure roller which define a nip portion there-between for the passage of photosensitive media to be developed. The media is of the type that includes microcapsules on an imaging side thereof. The pressure roller located on the non-imaging side of the media includes a non-metallic outer layer that reduces the amount of stress on a base of the media while permitting the application of a sufficient force by the pressure roller located on the imaging side of the media to rupture selected microcapsules.

A thermal printer is adapted to prevent crease formation in a dye transfer area of a dye donor web that can cause line artifacts to be printed on a dye receiver during a dye transfer from the dye transfer area to the dye receiver in a dye transfer printer.

A liquid dispenser includes first and second liquid chambers. The second liquid chamber is in fluid communication with liquid supply and liquid return channels. A flexible membrane separates and fluidically seals the first and second liquid chambers from each other. The flexible membrane, residing in a first position, includes a residual compressive stress that exceeds an onset buckling stress of the flexible membrane. A heater, associated with the second liquid chamber, is selectively actuated to create a pressure pulse in a liquid that causes the flexible membrane to move from the first position to a second position to eject liquid through a nozzle of the first liquid chamber. In one embodiment, a liquid supply provides liquid that flows continuously from the liquid supply through the liquid supply channel through the second liquid chamber through the liquid return channel and back to the liquid supply during a drop dispensing operation.

A device and a method of controlling fluid flow are provided. The method includes providing a moving fluid including a fluid flow characteristic; providing a fluid control device including a fluid control surface, the fluid control surface including a pattern that guides the fluid; causing the fluid to contact the fluid control surface of the fluid control device; and causing the fluid to interact with the fluid control surface of the fluid control device by guiding the fluid using the pattern of the fluid control surface while the fluid is in contact with the pattern of the fluid control device such that the fluid flow characteristic of the fluid after interacting with the fluid control surface of the fluid control device is different from the fluid flow characteristic of the fluid before interaction with the fluid control surface of the fluid control device.

A drop generator operable to selectively form a drop having a first size and a drop having a second size from liquid emitted through a nozzle associated with the drop generator. The drop having the first size and the drop having the second size travel along a drop trajectory with the first size being larger than the second size when compared to each other. Each of the drops has a drop velocity. A gas flow deflection system includes a gas flow that is directed at a deflection zone that comprises at least a portion of the drop trajectory. The gas flow in the deflection zone includes a velocity vector having a parallel velocity component and a perpendicular velocity component with the parallel velocity component and the perpendicular velocity component being defined relative to the drop trajectory.

A printing system includes a liquid drop ejector, a fluid passage, and a fluid flow source. The liquid drop ejector is operable to form liquid drops having a plurality of volumes moving along a first path. The fluid passage includes a wall. A source of acoustic energy is associated with the wall. A fluid flow source is associated with the passage and is configured to provide a fluid flow through the passage. Interaction of the fluid flow and the liquid drops causes liquids drops having one of the plurality of volumes to begin moving along a second path.
