CONTROL METHOD OF INKJET PRINT HEAD, INKJET PRINT HEAD SUITABLE FOR USING THAT METHOD, AND INKJET PRINTER COMPRISING THAT PRINT HEAD

摘要

PROBLEM TO BE SOLVED: To provide a control method of an inkjet print head including a substantially closed duct having an ink outlet and set with ink. SOLUTION: The control method of an inkjet print head comprises a step for applying an operating pulse to an electromechanical transducer in order to vary the pressure in the duct such that an ink drop is ejected from the outlet, a step for measuring the electrical impedance of the electromechanical transducer, and a step for adapting the operating pulse based on the measured impedance.
