ABSTRACT:
A printing method for application in an inkjet printer containing a substantially closed ink chamber and a nozzle, said ink chamber being operationally connected to an electro-mechanical converter, which includes the steps of printing an image for the purposes of which the converter is actuated according to a predetermined printing strategy in order to eject ink drops from the nozzle for the formation of the image onto a carrier; detecting the presence of an obstruction, in particular a gas bubble, inside the ink chamber during printing: interrupting the printing process: modifying the printing strategy in such a way that the obstruction will not produce ink chamber failure while the process of printing the image continues by actuating the converter using the modified printing strategy: and continuing the printing process by application of the modified printing strategy. An inkjet printer which has been modified for using the present method is also provided.
