| 20090246377 | THERMAL INK JET INK COMPOSITION - Disclosed are ink jet ink compositions suitable for use in thermal ink jet printers. The ink jet ink compositions contain one or more volatile organic solvents, one or more humectants, one or more binder resins, and one or more colorants. The ink jet ink compositions may also contain additives such as a plasticizer and/or a surfactant. Embodiments of the ink jet ink compositions have short dry times, good adhesion to a variety of substrates, and/or long decap times. | 10-01-2009 |
| 20090273621 | SYSTEM AND METHOD FOR MAINTAINING OR RECOVERING NOZZLE FUNCTION FOR AN INKJET PRINTHEAD - A transducer capable of generating vibrational energy is positioned relative to an inkjet cartridge to impart a vibrational force to simultaneously vibrate at least a portion of each of a plurality of ink fluidic columns associated with a plurality of nozzles in a printhead of the inkjet cartridge to maintain or recover nozzle function. | 11-05-2009 |
| 20090289971 | Ink Containment System and Ink Level Sensing System for an Inkjet Cartridge - An ink containment system for an inkjet cartridge, for storing ink for printing, comprises a housing having a plurality of walls. A rigid basin member and a rigid moveable plate are disposed within the housing. A flexible membrane is affixed to a surface of the basin member and to a surface of the plate forming an ink reservoir within the basin member, plate and flexible membrane. A spring-biased mechanism is disposed between the basin member and plate, for biasing the plate apart from the basin member, generating a negative pressure within the ink reservoir and the basin member remaining stationary relative to the movement of the plate. | 11-26-2009 |
| 20090303299 | INK CONTAINMENT SYSTEM AND INK LEVEL SENSING SYSTEM FOR AN INKJET CARTRIDGE - An ink containment system for an inkjet cartridge, for storing ink for printing, comprises a rigid basin member and a rigid moveable plate. A flexible membrane is affixed to a surface of the basin member and to a surface of the plate forming an ink reservoir within the basin member, plate and flexible membrane. A spring-biased mechanism is disposed between the basin member and plate, for biasing the plate apart from the basin member, generating a negative pressure within the ink reservoir and the basin member remaining stationary relative to the movement of the plate. The basin member has a bowl-like configuration and the spring is seated within the reservoir in such a way that when the ink reservoir has collapsed due to depletion of ink, the flexible membrane and moveable plate are substantially flush with surfaces of the basin member. | 12-10-2009 |
| 20100098860 | THERMAL INK JET INK COMPOSITION - A thermal ink jet ink composition includes one or more volatile organic solvents, one or more humectants, one or more binder resins, and one or more dyes. The one or more volatile organic solvents are selected from C | 04-22-2010 |
| 20100328401 | THERMAL INK JET INK COMPOSITION - A solvent-based inkjet ink composition for inkjet printing includes at least 50 weight percent solvent, a colorant, a humectant, from 0.3 weight % to 8 weight % of a binder resin, and not more than 5 weight percent water. The ink composition is compatible with components of a thermal ink jet printer. | 12-30-2010 |
| 20110141191 | SYSTEM AND METHOD FOR MAINTAINING OR RECOVERING NOZZLE FUCTION FOR A PRINTHEAD - A transducer capable of generating vibrational energy is positioned relative to an inkjet cartridge to impart a vibrational force to simultaneously vibrate at least a portion of each of a plurality of ink fluidic columns associated with a plurality of nozzles in a printhead of the inkjet cartridge to maintain or recover nozzle function. | 06-16-2011 |
