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.

Ink delivery system and methods for improved printing

An ink delivery system having at least one off-axis ink supply container and an on-axis printhead assembly. The 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 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.

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.

Fluid container

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.
