  • Ink delivery system and methods for improved printing
    Patent number: 7997698
    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.
    Type: Grant

  • Rejuvenation station and printer cartridge therefore
    Patent number: 6840603
    Abstract: A rejuvenation station has a housing with a first area adapted to hold a fluid supply, and a second area adapted to hold a printer cartridge. In the first area is a first fluidic interconnect that is adapted to couple with the fluid supply. In the second area is a second fluidic interconnect that is adapted to couple with the printer cartridge. A fluid path in the housing couples the fluidic interconnects. An actuator extracts fluid from at least one of the fluid supply and the printer cartridge, and inserts fluid into the printer cartridge through the fluid path.
