INKJET SYSTEM AND ITS MANUFACTURING METHOD AND ITS USE

摘要

PROBLEM TO BE SOLVED: To provide an inkjet system capable of checking a signal generated by a piezoelectric actuator through the use of a simple electronic device in a short time. SOLUTION: The invention relates to an inkjet system comprising a printhead equipped with an ink fillable chamber operatively connected to a piezoelectric actuator and provided with a nozzle for the ejection of ink drops in response to a current energized by the actuator. The actuator is connected to a measuring circuit for measuring an electric signal generated by the actuator in response to its deformation, wherein the system is so configured that a natural frequency of the inkjet system corresponds substantially to a natural frequency of a disturbance in the system.
