Abstract
An Inkjet apparatus is provided. An Inkjet apparatus includes a piezoelectric inkjet print head, a plurality of driving unit, a detection unit and a control unit. The piezoelectric inkjet print head comprises a plurality of nozzles, wherein each the nozzle outputs an ink drop according to a driving voltage. The driving unit generates the driving voltage according to a control signal. The detection unit detects a state of the ink drop corresponding to the nozzle to generate a detection signal. The control unit generates the control signal to control the driving voltage according to the detection signal.
