A control system for controlling a driving pulse applied to a piezoelectric element (112) of an inkjet head is disclosed. A variable-voltage source (104, 105) produces a control voltage (VL, VT) depending on a control signal (SL, ST) and a pulse generator (SWL, SWT, 106-109) generates the driving pulse (VDRV) having a voltage waveform with a slope determined depending on the control voltage. A peak voltage of the driving pulse is monitored by a monitor (110, 111) and the control signal is adjusted so that the peak voltage (VM) reaches a predetermined voltage (VP). <IMAGE> |
