Printhead chip incorporating laterally displaceable ink flow control mechanisms |
摘要 |
A printhead chip includes a substrate that incorporates drive circuitry and that defines nozzle chambers and nozzle chamber inlets on an inlet side of the substrate. A structural layer on an ink ejection side at the substrate defines ink ejection ports in fluid communication with respective nozzle chambers. Closure members on the ink inlet side are displaceable in a plane substantially parallel to the inlet side between open positions in which ink can enter the nozzle chambers and closed positions in which the inlets are closed. Micro-electromechanical drive mechanisms are connected to the drive circuitry and engaged with the closure members to displace the closure members between the open and closed positions on receipt of an electrical signal from the drive circuitry.
