  • Patent number: 7540599
    Abstract: Some embodiments of the present invention provide an inkjet printhead within which a removable ink cartridge can be installed. Upon installation, the ink cartridge can be coupled to one or more wicks in the printhead for establishing fluid communication between one or more chambers in the ink cartridge and nozzles through which ink exits the printhead during operation. The wick can extend from a cartridge receptacle to a substantially enclosed ink reservoir in order to transport ink from the removable cartridge to the ink reservoir.
    Type: Grant

  • Patent number: 7159974
    Abstract: An inkjet assembly comprising a vented ink reservoir for containing a liquid ink therein, the vented ink reservoir defining an internal volume occupied at least in part by a semipermeable membrane in fluid communication with a vent that automatically adjusts for pressure differentials by enabling gaseous diffusion between an environment external to the vented ink reservoir and the internal volume of the vented ink reservoir, while inhibiting liquid diffusion therethrough. A method is also disclosed for mounting the semipermeable membrane to at least one of an ink reservoir cap and an ink tank.

  • Publication number: 20040257412
    Abstract: A method of assembling a print head that includes the steps of: (a) providing a print head base including a nozzle and at least one ink channel; (b) mounting in fluid communication with the at least one ink channel of the print head base an ink regulator that includes: (i) a pressurized chamber including an ink inlet in fluid communication with an ink source, an ink outlet in fluid communication with the at least one ink channel of the print head base, and an exterior flexible wall having an inner surface facing an interior of the pressurized chamber, (ii) a valve biased to restrict fluid communication between the ink source and the pressurized chamber, where the exterior flexible wall actuates the valve to overcome the bias in response to a predetermined pressure differential across the exterior flexible wall to provide fluid communication between the ink source and the pressurized chamber, where the fluid communication between the pressurized chamber and the ink source decreases the pressure differential ac

  • Publication number: 20040257414
    Abstract: A method of assembling an ink filtration system in fluid communication with an ink source comprising the steps of: (a) providing a printhead base including at least one ink channel in fluid communication with at least one nozzle; (b) positioning an ink filter in fluid communication with at least the one ink channel of the printhead base; and (c) laser welding the ink filter in series with the printhead base to provide a sealed fluidic interface therebetween ensuring that ink within at least the one ink channel has passed through the ink filter. Also disclosed are methods and resulting apparatuses utilizing laser welding to mount components of an ink cartridge for use with an inkjet printer.
