Abstract:
A network-based publication system, to publish data over a communications network, includes an interface to receive, via the communications network and from a first user, user data to be published by a network-based publication system. The publication system further includes a publisher component to generate publication data (e.g., an HTML document) including the user data and function modifying code. The publisher component generates the publication data in accordance with a publication format. The interface publishes the publication data via the communications network. The function modifying code is interpreted and executed, at a browser application, to disable (or modify) least one function of programming language supported by the browser application.
Abstract:
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.A method for controlling effects of accumulated air in a printhead assembly. The printhead assembly has at least one ink reservoir and one standpipe separated by a particle filter. The printhead assembly is fluidicly connected to at least one off-axis ink supply container by at least one tube. The method includes drawing air from said printhead assembly through said standpipe into the tube.
Abstract:
A peristaltic pump device and method includes at least one roller of a rotor rotatable with respect to an occlusion with a substantially constant radius. A depression is formed in the occlusion and extends beyond the substantially constant radius of the occlusion.
Abstract:
A positive stop capping system is provided for sealing an inkjet printhead in an inkjet printing mechanism during periods of printing inactivity. A positive stop or brace is provided in a cavity defined under a cap cover skin, with the skin also forming a sealing lip which surrounds ink-ejecting nozzles of the printhead when sealed. The flexible skin supporting the lip deflects into the cavity toward the brace when the cap is moved into a sealing position, in some cases contacting the brace, and in other cases, compressing the brace. An inkjet printing mechanism having the positive stop capping system and method of capping using this system are also provided.

Abstract:
A pump having a rotary portion which compels the movement of a fluid by peristaltic compression of resilient tubing containing the fluid includes a tube component having a plurality of adjacent resilient tubes, with a web interconnecting the adjacent resilient tubes. The web may be offset from the centerline of the tubes so as not to degrade the compressibility of the tubes.
Abstract:
The present invention includes as one embodiment a capping station for a fluid ejection device having a snout feature, the capping station comprising a cap with a rigid body and a gland seal disposed around an inner perimeter of a cavity defined by the rigid body for resiliently receiving side portions of the snout feature of the fluid ejection device to create a seal with the fluid ejection device.

Abstract:
A system for receiving and recycling ink comprises a print cartridge having a printhead, and an ink supply reservoir fluidly connected to the print cartridge and a seal member coupled to the ink supply reservoir. The seal member defines a fluid path into the reservoir and the print cartridge engages the seal member so that ink spit from the printhead flows through the fluid path into the reservoir.
Abstract:
A ganged inkjet printhead sealing system maintains inkjet printhead health in an inkjet printing mechanism during periods of printing inactivity. In multi-printhead printing mechanisms, separate caps seal against each of the printheads. The caps each have an outlet vent. The vents are all ganged together and fluidically coupled to a single, common pressure regulation chamber that isolates the environment adjacent the printhead nozzles from the external environment when the printheads are capped. A fluid in a U-shaped manometer tube, or an elastomeric bladder are used to isolate the pressure chamber environment. The bladder may be constructed as a thin-walled sheet, a spring-biased bag, or as a bellows. The pressure chamber volume changes to accommodate pressure spikes during the capping process, as well as environmental changes in temperature, elevation, barometric pressure, etc. An inkjet printing mechanism having such a ganged capping system, along with associated capping methods are also provided.
