Abstract:
An inkjet printhead with integral compensation for misdirection of ink drops ejected through at least one nozzle of the printhead comprising:a substrate forming a wall which defines a nozzle cavity adapted for facilitating the flow of ink from an ink reservoir; a membrane predisposed about said nozzle cavity to create a resistive barrier against ink flow, said membrane including a nozzle opening through which ink drops are ejected; a first disk positioned over said nozzle opening, said first disk having an aperture about its axis; and one or more actuators configured to move said first disk so that said aperture is controllably offset from said nozzle opening; wherein said first disk is adapted to cause ink ejected from said nozzle opening via said aperture to be deflected with regard to a desired amount of compensation when said aperture is offset from said nozzle opening.
