| 20100149238 | THERMAL CLEANING OF INDIVIDUAL JETTING MODULE NOZZLES - A liquid ejection device includes a jetting module including an array of nozzles; a thermal stimulation device associated with each nozzle of the array of nozzles; and a controller in electrical communication with each thermal stimulation device. The controller is configured to provide a first activation waveform to each thermal stimulation device and to provide a second activation waveform to each thermal stimulation device to clean the associated nozzle with liquid emitted from the associated nozzle. The second activation waveform has a higher activation component when compared to the first activation waveform. | 06-17-2010 |
| 20100271436 | PRINTHEAD WITH LIQUID FLOW THROUGH DEVICE - A liquid drop ejector is disclosed including a nozzle structure and a thermal actuator. The nozzle structure includes a nozzle and a wall. The nozzle includes an end and the wall extends from the end of the nozzle. The thermal actuator is associated with at least one of the nozzle and the wall, and is operable to add surface energy to at least one of the nozzle and the wall to cause a directional change in a liquid flowing through the nozzle structure. | 10-28-2010 |
| 20100293787 | METHOD OF MANUFACTURING A POROUS CATCHER - According to one feature of the present invention, a method of manufacturing a porous catcher includes providing a catcher face material layer; forming pores in the catcher face material layer using a first etching process that is controlled by a first photolithographic mask; providing a reinforcing structure material layer that is in mechanical contact with the porous catcher face; forming openings in the reinforcing structure material layer using a second etching process that is controlled by a second photolithographic mask; and fluidically connecting the openings in the reinforcing structure and the pores of the catcher face using a material removal process. | 11-25-2010 |
| 20100295910 | PRINTHEAD WITH POROUS CATCHER - A printhead includes a catcher and a negative pressure source. The catcher includes a liquid drop contact structure. The liquid drop contact structure includes a plurality of pores, each of the plurality of pores having a substantially uniform size when compared to each other. The plurality of pores have a critical pressure point above which air can displace liquid from the plurality of pores. The negative pressure source is in fluid communication with the plurality of pores of the liquid contact structure. The negative pressure source includes a pressure regulator to control the negative pressure such that the negative pressure remains below the critical pressure point of the plurality of pores of the liquid drop contact structure. | 11-25-2010 |
| 20100295912 | POROUS CATCHER - A catcher for use in a continuous printhead includes a liquid drop contact structure and a reinforcing structure. The liquid drop contact structure includes a plurality of pores with each of the plurality of pores having a substantially uniform size when compared to each other. The reinforcing structure, which is in contact with the liquid drop contact structure, includes a plurality of fluid channels through which liquid from the plurality of pores can be removed. | 11-25-2010 |
| 20110012967 | CATCHER INCLUDING DRAG REDUCING DROP CONTACT SURFACE - A catcher and a method of printing are provided. The catcher includes a liquid drop contact face. The liquid drop contact face includes an opening that creates an air cushion upon which liquid flows after a liquid drop contacts the drop contact face. | 01-20-2011 |
| 20120026251 | LIQUID FILM MOVING OVER POROUS CATCHER SURFACE - A printhead includes a jetting module that forms liquid drops travelling along a first path. A deflection mechanism causes selected liquid drops formed by the jetting module to deviate from the first path and begin travelling along a second path. A catcher includes a stationary porous surface. A liquid film flows over the stationary porous surface of the catcher. The catcher is positioned relative to the first path such that the liquid drops travelling along one of the first path and the second path contact the liquid film. | 02-02-2012 |
| 20120026253 | PRINTING USING LIQUID FILM POROUS CATCHER SURFACE - A method of printing provides liquid drops travelling along a first path using a jetting module. A catcher including a stationary porous surface is also provided. A liquid film is caused to flow over the stationary porous surface of the catcher using a liquid source. Selected liquid drops are caused to deviate from the first path and begin travelling along a second path using a deflection mechanism. The liquid drops travelling along one of the first path and the second path contact the liquid film. | 02-02-2012 |
| 20120026259 | LIQUID FILM MOVING OVER SOLID CATCHER SURFACE - A printhead includes a jetting module that forms liquid drops travelling along a first path. A deflection mechanism causes selected liquid drops formed by the jetting module to deviate from the first path and begin travelling along a second path. A catcher includes a liquid outlet, a stationary surface, and a liquid source that causes a liquid film to exit the liquid outlet and flow over the stationary surface of the catcher. The catcher is positioned relative to the first path such that the liquid drops travelling along one of the first path and the second path contact the liquid film. | 02-02-2012 |
| 20120026260 | PRINTING USING LIQUID FILM SOLID CATCHER SURFACE - A method of printing includes providing liquid drops travelling along a first path using a jetting module. A catcher including a liquid outlet, a stationary surface, and a liquid source is also provided. A liquid film provided by the liquid source is caused to exit the liquid outlet of the catcher and flow over the stationary surface of the catcher. Selected liquid drops are caused to deviate from the first path and begin travelling along a second path using a deflection mechanism such that the liquid drops travelling along one of the first path and the second path contact the liquid film. | 02-02-2012 |
