    摘要： A printhead is provided having an ejection surface having a plurality of nozzles for ejecting droplets and a nozzle guard positioned over the ejection surface and having a plurality of channels therethrough aligned with the nozzles. The channels have hydrophobic sidewalls and are radially flared with respect to the ink ejection surface such that droplets which are ejected from the nozzles with misdirection rebound off the channel sidewalls to pass through the channels.

    摘要： A thermal inkjet printhead with generally planar heater elements disposed in respective bubble forming chambers such that they are bonded on one side to the chamber so that the other side faces into the chamber. Each heater element receives an energizing pulse to heat ejectable liquid above its boiling point to form a gas bubble on the side facing into the chamber, whereby the gas bubble causes the ejection of a drop of the ejectable liquid from the nozzle. The chamber has a dielectric layer proximate the side of the heater element bonded to the chamber. The dielectric layer has a thermal product less than 1495 Jm−2 K−1s−1/2, the thermal product being (ρCk)1/2, where ρ is the density of the layer, C is specific heat of the layer and k is thermal conductivity of the layer. The present invention reduces the drop ejection energy and the heat dissipation into the printhead IC by improving the thermal isolation between the heater and the substrate.

    摘要： The invention provides for a micro-electromechanical nozzle arrangement for an inkjet printhead. The arrangement includes a substrate defining an inverted pyramidal ink chamber with a vertex thereof terminating at an ink supply channel defined by the substrate, said substrate having a layer of CMOS drive circuitry. The arrangement also includes a roof structure connected to the drive circuitry layer and covering the ink chamber, the roof structure defining a fluid ejection nozzle rim above said chamber. Also included is a plurality of actuators fast with and displaceable with respect to the roof structure, the actuators radially spaced about the nozzle rim between the guide rails. Each actuator has a serpentine heater element configured to expand thermally upon receiving current from the drive circuitry thereby moving said actuators into the chamber to increase a fluid pressure inside the chamber to eject a drop of ink via the ejection nozzle. Each actuator is cantilevered to a heater element in a bendable manner.
