Abstract
Provided is an error detection apparatus of an inkjet printer head including: an amplification unit connected between a piezoelectric element, which applies pressure to an ink chamber, and a ground to amplify a voltage generated from the piezoelectric element; and a detection unit for detecting whether ink is normally ejected using the voltage amplified by the amplification unit. It is possible to detect whether the inkjet printer head abnormally ejects ink by sensing vibration after ejection of ink using the piezoelectric element.
