Defect detection device of a print head and method of detecting defect of a print head |
摘要 |
A defect detection device of a printer head, and a method of detecting defects, including first to Nth actuators providing a driving force for ejecting ink to ink chambers; a vibration signal generator generating vibration signals for vibrating the first to Nth actuators; a first switch receiving the generated vibration signals and outputting the vibration signals to a Kth actuator among the first to Nth actuators; a second switch receiving vibration signals of one or more among the first to Nth actuators and outputting an Lth vibration signal that corresponds to a vibration signal of the Lth actuator adjacent to the Kth actuator among the received vibration signals; and a defect detector comparing the Lth vibration signal output from the second switch with the specific vibration signal of the Lth actuator when there is no defect in a printer head and detecting defects in the printer head.
