Abstract: An ink jet printer apparatus is adapted to secure a print cartridge which includes an open container having a top opening; a porous ink-absorbent in the container; a print head in ink communication with the porous ink-absorbent; a top cover lid adapted to be placed on the container, over the top opening, to close the container; and an ink conduit needle mounted on the top cover lid to longitudinally extend in a horizontal orientation above the porous ink-absorbent when the cover lid is placed on the container, so that a print ink can descend freely by the force of gravity from the ink conduit needle onto the porous ink-absorbent and from the porous ink-absorbent down to the print head.

Abstract: An apparatus and method for guiding recording media through a printer comprises a roller unit which is coupled to the printer and which comprises a plurality of roller wheels.

Abstract: An ink reservoir container for an ink jet printer comprises an ink outlet, a first mounting location for the ink outlet, and an alternative second mounting location for the ink outlet. The container is useful in a double plumbed ink jet printer.

Abstract: A moving belt accurately transports a wide variety of media through the print zone of an ink jet printer without distortion caused by tension in the media and without pinch rollers, star wheels, nip rollers, or other media transport assisting apparatus. The belt may be horizontally mounted and may comprise a coated paper material for ink absorption and high sliding friction characteristics.

Abstract: An ink reservoir container for an ink jet printer comprises an ink outlet, a first mounting location being located on a print carriage for mounting the ink outlet, and an alternative second mounting location being located on the print carriage for mounting the ink outlet. The container is useful in a double plumbed print carriage of the ink jet printer.

Abstract: An inkjet printer uses large volume ink reservoir containers to supply ink to ink cartridges located on a movable print carriage. A communication link including tubing sections and quick disconnect fittings couples the large volume ink reservoir containers and the ink cartridges. The printer may be plumbed with more ink supply tubing sections than ink cartridges and ink reservoirs for the provision of different ink types. The changing of sets of large volume ink reservoir containers or sets of ink cartridges is more convenient with the use of quick disconnect fittings.

Abstract: An apparatus and method for guiding recording media through a printer comprises a pinch roller which is pivotally coupled to the printer. The pinch roller may have a plurality of roller wheels. The degrees of freedom of the pinch roller allows the pinch roller to adjust its position and orientation with variations in the direction of motion of the recording medium as it is being fed through the printer.
