A method of controlling an inkjet printhead, an inkjet printhead suitable for use of said method, and an inkjet printer comprising said printhead

摘要

The invention relates to a method of controlling an inkjet printhead containing a substantially closed duct in which ink is situated, said duct having an exit opening for the ink, the method comprising: applying an actuation pulse to an electro-mechanical transducer so that the pressure in the duct changes in such a manner than an ink drop is ejected from the exit opening, wherein the method further comprises: measuring the electric impedance of the electromechanical transducer and adapting the actuation pulse on the basis of the measured impedance.
