Abstract: PURPOSE: A fault detecting device of an inkjet printer head and a fault detecting method are provided to amplify an output generated by a piezoelectric element with residual vibration after discharging ink, thereby simply determining whether the ink normally discharged or not. CONSTITUTION: A fault detecting device(100) of an inkjet printer head comprises an amplifying unit(130) and a detecting unit(150). The amplifying unit is connected to between a piezoelectric element and a contact point. The piezoelectric element presses an ink chamber. The amplifying unit amplifies voltage generated by the piezoelectric element. The detecting unit detects whether ink is normally discharged or not by using the amplified voltage. The detecting unit compares the voltage amplified by the amplifying unit and a preference voltage saved in advance in normally discharging the ink.
