Inkjet printer head, inkjet printing system having the same, and control method thereof

摘要

An inkjet printing system to control actuators in real time. The inkjet printing system includes a waveform generator to supply electric power in the form of a predetermined wave, at least one actuator to change a pressure in an ink chamber according to the electric power from the waveform generator, at least one sensing unit to continuously detect and output a voltage value for the voltage outputted by the actuator, and a controller to calculate an inductive voltage value induced by a deformation of the actuator using the detected result from the sensing unit, and to adjust the waveform of the electric power supplied by the waveform generator according to the calculated inductive voltage value, thereby controlling the actuator.
