    Abstract: A printhead is provided for an inkjet printer. The printhead includes a wafer assembly defining a plurality of spaced apart groups of ink supply channels and a plurality of groups of ink ejection nozzle arrangements in fluid communication with respective ink supply channel groups. Each ink ejection nozzle arrangement includes a nozzle chamber structure mounted to the wafer assembly. Each ink ejection nozzle arrangement also defines a nozzle chamber for receiving ink from an ink supply channel and an ink ejection port through which ink in the nozzle chamber can be ejected. An anchor extends from the wafer assembly in a location external to the nozzle chamber. An elongate thermal actuator mechanism extends from the anchor and into the nozzle chamber. A pit is defined adjacent each nozzle chamber structure for catching ink and thereby impeding spilt ink from spreading across the printhead.

    Abstract: A thermal actuator for a micro-electromechanical device such as an inkjet printer nozzle. The actuator has: (a) a base element; (b) a cantilevered element including a thermo-mechanical bender portion extending from the base element and a free end tip residing in a first position, the thermo-mechanical bender portion having a base end adjacent the base element and a free end adjacent the free end tip; and (c) apparatus adapted to apply a heat pulse having a spatial thermal pattern directly to the thermo-mechanical bender portion, causing the deflection of the free end tip of the cantilevered element to a second position, and wherein said spatial thermal pattern results in a substantially greater temperature increase of the base end than the free end of the thermo-mechanical bender portion. By designing the actuator such that the material with a high coefficient of thermal expansion heats with a predetermined spatial thermal pattern concentrated toward the base of the cantilever beam, the paddle end movement is greater and faster. The ink above the paddle is given the necessary pressure such that the ink in the bulging meniscus has sufficient momentum to break the surface tension and form a drop.

    Abstract: A thermal bend actuator includes a wafer substrate. An elongate actuator arm is fixed to the substrate at a fixed end. The elongate actuator arm includes a heater layer of a conductive material and a dielectric, resiliently flexible layer. The heater layer defines a heater circuit which is connected to an electrical potential. A working member is fixed to an opposite free end of the actuator arm. Control logic circuitry is positioned on the substrate, between, and generally aligned with, the heater layer and the substrate. The control logic circuitry is interconnected between a data input means and the heater circuit and includes register circuitry connected to the data input means to generate an enabling signal. Firing circuitry is connected between the register circuitry and the heater circuit to close the heater circuit on receipt of the enabling signal so that said electrical potential generates a current in the heater circuit, resistively to heat the heater layer. At least the heater layer is of a material that has a coefficient of thermal expansion which is such that the heater layer can expand on heating and contract on cooling to do work. The heater layer is positioned so that the elongate actuator arm experiences differential thermal expansion and contraction and thus reciprocally displaces the working member.
