摘要： A method for controlling printing actions of a print head (1) comprising pumps (10) filled with ink (18), and actuators (16) for generating actuation pulses acting on the ink (18), comprises the step of determining a characteristic frequency of the pumps (10). As the characteristic frequency of the pumps (10) is directly related to the geometry of the pumps (10), the characteristic frequency can be used as an indicator of the state of the pumps (10) and the volume of the ink droplets emitted by the pumps (10). In case a slight change of the characteristic frequency is detected, the actuation pulse is adjusted in order to still meet the requirements regarding the volume of the ink droplets. In case a relatively large change of the characteristic frequency is detected, the printing action of the pump (10) concerned is stopped, and may be taken over by another pump (10).
