An inkjet printer includes a substantially closed ink duct in which ink is situated. The duct is operationally connected to a piezo-element,. The piezo-element is actuated with a number of actuation signals with appropriate waveforms, generated by a first and second signal generator in order to eject ink drops from the duct nozzle. A pressure wave is generated in the duct by an actuation pulse. The pressure wave causes a deformation of a piezo-element, which generates an electric signal as a result. The waveforms of the first and second signal may be different and do not have to be directly subsequent in time.
