ABSTRACT:
A microelectromechanical fluid ejection device configured for detecting a fault condition is provided. The device comprises a mechanical actuator, drive circuitry and a switch device. The actuator is displaceable upon receipt of an electrical current from the drive circuitry and the displacement causes ejection of fluid from an aperture in the device. The switch device determines an extent of displacement of the actuator and comprises a contact element positioned for contact with the actuator; and processing circuitry for detecting when the actuator makes contact with the contact element.
