Abstract
An appropriate pulse width of a driving pulse for driving a piezoelectric element of ink jet head is determined by using the head difference. That is, the pulse width with which the least change in the ink speed occurs can be used as the pulse width of the driving signal for the piezoelectric actuator. As a result, a reliable ink jet printer head capable of stably ejecting ink droplets over a long period of time and having excellent frequency characteristics can be provided.
