Abstract
The invention relates to a method for monitoring a performance of a jetting device, the jetting device being configured to expel droplets of an electrically conductive fluid wherein at least a part of the conductive fluid is positioned in a magnetic field, the method comprising providing an electrical actuation current in the part of the conductive fluid positioned in the magnetic field, thereby generating a pressure wave in the conductive fluid; characterized in that the method further comprises detecting a resulting electrical current, which electrical current is induced by a residual pressure wave in the part of the conductive fluid positioned in the magnetic field, thereby obtaining a detection signal and based on the detection signal determining whether the jetting device is in an operative state. The invention further relates to a printing device, employing the described method.
