Abstract
A method and system for application in an inkjet printer containing a substantially closed ink duct in which ink is situated, said duct being operationally connected to an electromechanical transducer, the method including the steps of: actuating the transducer with a number of actuation pulses according to a predetermined actuation setting in order to eject ink drops from a duct nozzle, where a pressure wave is generated in the duct by an actuation pulse, this pressure wave causing a deformation of an electromechanical transducer which generates an electrical signal; analyzing the electrical signal; analyzing the signal for a plurality of different actuation settings, and based on which analysis, determining an actuation setting, on the one side of which setting the ejection of a drop is a stable process and on the other side of which setting, the ejection of a drop is an unstable process.
