Abstract: A ballistic aerosol marking device includes, marking material which flows from a material reservoir to a delivery channel via a port. Flow of marking material is facilitated by the creation of a fluidized bed or aerosol of marking material in the reservoir. Gas flow together with mechanical or electromechanical assistance can be used to assist in the generation of the fluidized bed or aerosol.

Abstract: An air pressurization system is incorporated as part of a replaceable auxiliary ink supply for an ink jet printer. The auxiliary ink supply cartridge includes a pressurized container having air, ink and electrical signal connections. The air pressure applied to the auxiliary ink supply is monitored to be maintained in a predetermined range in accordance with a start-up sequence, an operational sequence, a waiting time, and a close-down sequence.

Abstract: An inkjet printing arrangement having a series of nozzles for the ejection of ink wherein the nozzle rims are formed as a result of the deposition of a rim material layer and a subsequent planar etching of the material layer so as to form the nozzle rim. The planar etching can comprise chemical-mechanical planarization of the rim material layer and any associated sacrificial layers.

Abstract: A fluid cartridge, such as a cartridge for filling with ink for use in ink jet printhead includes a wick chamber that has outer walls, including a top wall, and an ink chamber formed of a plurality of outer walls. A fluid conduit connects the ink chamber and the wick chamber. The outer walls of the ink chamber are formed to provide no fluid communication between the ink chamber and the ambient environment, except through the fluid conduit and the wick chamber. A vent opening through the top wall of the wick chamber provides communication between the wick chamber and the ambient environment, and an outlet opening through an outer wall other than the top wall of the wick chamber provides fluid communication for the ink to flow from the wick chamber. A vent tube extends from the vent opening into the interior of the wick chamber, and projections extend from the top wall of the wick chamber into the interior of the wick chamber, farther than does the vent tube.

Abstract: The invention provides an improved ink jet cartridge for an ink jet printer and a method for making the improved ink jet cartridge. The ink jet cartridge includes a substantially inflexible frame having at least one pressure port, the frame having at least one peripheral edge. At least one malleable web is provided having a first side and a second side the first side being attached to the peripheral edge of the frame defining a substantially closed cavity. The malleable web is conformed to the cavity by applying a subatmospheric pressure to the cavity before, after or while heating the malleable web in order to substantially conform the web to the cavity thereby creating a variable volume cavity having a substantially predictable pressure/volume relationship. A biasing element is disposed adjacent the first or second side of the malleable web for biasing the web relative to the cavity.

Abstract: A container (1) is proposed for replenishing ink or solvent in an ink jet printer ink system. The container (1) has a plug-in connector (7) for attachment to a mating connector on the ink system along an axis so that fluid within the container (1) can be transferred to the ink system. Adjacent to the connector (7) a cam surface is disposed so as to cause the connector (7) to disconnect from the mating connector on rotation of the container (1) in a direction about the axis.

Abstract: A storage container for storing inkjet cartridges when removed from the carriage of a printer having caps for capping each cartridge, cleaning member for cleaning the electrically conductive interconnect pads of a cartridge as it is positioned within the storage container. The cleaning member may comprise abrasive cleaner for mechanically scraping or wiping the electrically conductive interconnect pads of the inkjet cartridge as it is inserted into and/or removed from the container and preferable comprises a flex circuit. The provision of cleaning member within a storage container reduces the chances of poor or defective electrical contact being made to a cartridge when it is returned to the printer.

Abstract: A gradation correction data used in correcting the gradation of the printed image is recorded on the leader film of the ink ribbon in a form of optically readable marks. Then the ink ribbon is set in a thermal printer, the marks are read out by an optical sensor to obtain the gradation correction data. Then, the gradation correction of the image data to be printed is carried out by referring to the correction data thus obtained prior to the actual printing of the image data.

Abstract: An ink jet printing system comprises multiple print cartridges each containing a different ink and having a plurality of printhead nozzle arrays scanning across printing media in a printing zone. After a specified amount of ink has been dispensed, an ink jet printhead carriage is moved to a refill station for ink replenishment. A label on a print head service module displays encoded visual indicia which are sensed by an optical sensor on the ink jet printhead carriage. The optical sensor is used to read pre-encoded information as well as on the fly information which is recorded on a label when the carriage moves along a traverse path to the printhead service station.

Abstract: An apparatus for printing variable identifying information on the face of tape is disclosed. In a particular application, the apparatus replaces a labeling station and is combined with a case sealing station to seal cases of products with adhesive sealing tape on a conventional production line. The apparatus includes a variable image printer, and preferably a thermal printer. The thermal printer preferably includes a thermal transfer print head and a thermal transfer ribbon. The tape is dispensed from a tape unwind spool and is routed past the print head with the thermal transfer ribbon positioned between the print head and the face of the tape, and the face of the tape opposite the print head. The thermal transfer ribbon is specially formulated to be compatible with the physical characteristics and chemical composition of the tape.
