  • Patent number: 7703900
    Abstract: There is provided an ink pressure regulator for regulating a hydrostatic pressure of ink supplied to an inkjet printhead. The regulator comprises: an ink chamber having an ink outlet for fluid communication with the printhead via an ink line; an air inlet open to atmosphere; a bubble outlet positioned for bubbling air into ink contained in the chamber; and an air channel connecting the air inlet and the bubble outlet. The bubble outlet is dimensioned to control a Laplace pressure of air bubbles drawn into the ink as result of supplying ink to the printhead. Hence, the hydrostatic pressure of the ink is regulated.

  • Publication number: 20090231401
    Abstract: An inkjet printer with a printhead and a conduit connected to the printhead. The conduit defines a flow path for the printing fluid and has an internal cross section configured such that the surface tension of printing fluid within it favors gas bubble growth along the conduit length over radial bubble growth that would fully occlude the flow path.

  • Publication number: 20090214392
    Abstract: A nano-fluidic trapping device and method of fabrication are disclosed. In one embodiment, a nano-fluidic trapping device for assembling a SERS-active cluster includes a substrate. The nano-fluidic trapping device further includes a SERS-active cluster compartment. The SERS-active cluster is formed in the SERS-active cluster compartment. In addition, the nano-fluidic trapping device includes a reservoir. The reservoir allows introduction of target molecules into the nano-fluidic trapping device. Moreover, the nano-fluidic trapping device includes a microchannel. The microchannel allows the target molecules to be introduced to the SERS-active cluster compartment from the reservoir. The nano-fluidic trapping device also includes a nanochannel. The SERS-active cluster compartment, the reservoir, the microchannel, and the nanochannel are disposed within the substrate.

  • Publication number: 20090096846
    Abstract: An inkjet printer that has a printhead for printing onto a media substrate, and a reservoir for containing a quantity of ink, the reservoir having a lower portion for holding ink and an upper portion defining a headspace of air above the ink. A fluid connection extends between the printhead and the reservoir. A pump draws air from the headspace to lower its air pressure and thereby controls the hydrostatic pressure of the ink at the printhead.

  • Publication number: 20090096853
    Abstract: There is provided an ink pressure regulator for regulating a hydrostatic pressure of ink supplied to an inkjet printhead. The regulator comprises: an ink chamber having an ink outlet for fluid communication with the printhead via an ink line; an air inlet; a regulator channel having a first end communicating with the air inlet and a second end communicating with a headspace of the chamber, the second end defining a bubble outlet; and a wetting system for maintaining at least some liquid in the regulator channel, thereby ensuring that air entering the headspace first passes through the liquid. The wetting system comprises a first wetting chamber connected to the first end, a second wetting chamber connected to the second end, and a liquid-retaining structure positioned in the second wetting chamber. The regulator channel, the first wetting chamber, the second wetting chamber and the liquid-retaining structure are all in fluid communication with each other.

  • Publication number: 20080143761
    Abstract: A method of regulating a hydrostatic pressure of ink supplied to an inkjet printhead is provided. The method comprises withdrawing a volume of ink from an ink chamber and simultaneously bubbling air bubbles into the chamber via a bubble outlet to balance the withdrawn volume of ink. Each air bubble is defined by an air cavity trapped inside a film or a body of ink. The bubble outlet is dimensioned to control a Laplace pressure of the air bubbles, thereby regulating a hydrostatic pressure of the ink.
