Abstract
A method of controlling an inkjet printhead with a substantially closed duct in which ink is disposed, which duct has an exit opening for the ink, the method including the actuation of an electromechanical transducer so that the pressure the duct changes in such a manner that an ink drop is ejected from the exit opening, said pressure causing a deformation of the transducer, whereby after the end of the actuation, an electric signal generated by the transducer is measured as a result of the deformation, wherein a subsequent actuation of the transducer is adapted to the measured signal.
