Printhead container and method. The container comprises an enclosure surrounding a printhead body having an ink channel terminating in a nozzle orifice. The ink channel has ink therein. The enclosure is capable of being pressurized to a predetermined internal pressure. The internal pressure acts on the ink to retain the ink in the channel, so that the ink is prevented from flowing along the channel and through the orifice. A one-way valve is in communication with the interior of the enclosure for ingress of a pressurizing medium into the interior of the enclosure, while avoiding reverse flow through the valve in order to allow sustained pressurization of the enclosure. Moreover, a support frame disposed in the enclosure may be provided, the frame defining a well sized to matingly receive the printhead body for constraining movement of the printhead body during transport of the enclosure.
For use in association with a printer, a container for a fluid-carrying body having a channel terminating in an orifice, the channel having a fluid therein, the container comprising an enclosure surrounding the fluid-carrying body, said enclosure defining an interior thereof pressurized to a predetermined internal pressure, the internal pressure acting on the fluid to retain the fluid in the channel, so that the fluid is prevented from flowing along the channel and through the orifice;
A container for a printhead, comprising:
For use in association with a printer, a container method for containing a fluid-carrying body having a channel terminating in an orifice, the channel having a fluid therein, the container method comprising the steps of surrounding the fluid-carrying body with an enclosure, the enclosure defining an interior thereof pressurized to a predetermined internal pressure, the internal pressure acting on the fluid to retain the fluid in the channel, so that the fluid is prevented from flowing along the channel and through the orifice;
A container method for containing a printhead body, comprising the steps of surrounding the printhead body with an enclosure, the printhead body having an ink channel having ink therein, the channel terminating in an orifice, the enclosure defining an interior thereof pressurized to a predetermined internal, the internal pressure acting on the ink to retain the ink in the channel, so that the ink is prevented from flowing along the channel and through the orifice;
