Abstract
A method of preparing an inkjet printhead, prior to generating an image onto a receiving medium, the printhead containing a substantially closed ink duct comprising an inlet opening and a nozzle, said duct being operationally connected to an electro-mechanical transducer, the method including the steps of arranging that the duct is filled with ink; generating a pressure wave in the ink, the pressure wave causing a deformation of the transducer which generates an electrical signal as a result; analyzing the electrical signal, and deciding on the basis of the analysis whether the inkjet printhead is ready to proceed with the printing of the image. The inkjet printer is also modified to perform the present method.
