Abstract: An ink delivery system having at least one off-axis ink supply container and an on-axis printhead assembly. The on-axis printhead assembly includes at least one reservoir and a corresponding standpipe separated by a particle filter. At least one tube connects the off-axis ink supply container to the on-axis printhead assembly. A first valve is configured to selectively open a flow path between the tube and the reservoir. A second valve is configured to selectively open a flow path between the standpipe and the tube.

Abstract: Exemplary embodiments of the invention include replaceable printing consumables with a variety of features that facilitate intuitive installation of the consumables in printers. The features may be utilized in various combinations to provide multiple, consistent visual cues to a printer user regarding the proper installation of the consumable. The consumables may be, for example, ink containers for inkjet printers.

Abstract: An on-axis ink reservoir that is pivotally secured to the carriage of an inkjet printer thereby defining an engaged position, in which the ink reservoir is in fluid communication with a printhead secured to the carriage, and an open position, in which the ink reservoir pivots away from the printhead to allow easy access to the printhead without the need to remove the ink reservoir from the carriage. Preferably, the ink reservoir is detachably secured to an ink-reservoir mounting portion, the printhead is detachably secured to a printhead mounting-portion, and these two mounting portions are pivotally secured together. More preferably, the ink-reservoir mounting portion includes a plurality of ink reservoirs, and the printhead mounting-portion includes a plurality of printheads. A latching mechanism is provided to operably secure the two mounting portions together in the engaged position.

Abstract: The present invention contemplates providing apparatus and methods for recommending to a consumer an optimal replacement consumable size, based on a record of the consumer's past utilization rate and on recommended intervention rate information stored in a memory device on the consumable.

Abstract: The present disclosure relates to a replaceable ink container for providing ink to an inkjet printing system. The inkjet printing system has a receiving station for receiving the replaceable ink container. The replaceable ink container includes a handle extending from a trailing end of the ink container for grasping the ink container for insertion into the receiving station. Also included is a latch for securing the replaceable ink container to the receiving station. The latch has an extended position for engaging the receiving station for securing the ink container to the receiving station and a retracted position. The latch is so disposed and arranged on the ink container to be urged from the extended position to the retracted position as the handle is grasped.

Abstract: The present invention is an inkjet print cartridge for use in an inkjet printing apparatus for forming images on print media. The inkjet print cartridge includes an inkjet printhead that is responsive to print control signals for ejecting ink drops onto print media. The inkjet printhead has a manufacturing tolerances associated therewith producing a range of drop weights. The inkjet printhead has a corresponding drop weight from the range of drop weights. Included with the inkjet print cartridge is an information storage device that is associated with the inkjet printhead for storing information for identifying the corresponding drop weight.
