RISO Technologies, formerly Toshiba Tec’s Inkjet Business Unit, continues to provide high-quality shear-mode piezoelectric printhead products to the industrial inkjet printing market since 2001. A non-destructive method has been developed to evaluate piezoelectric actuators by simple LCR measurement. With empirical equivalent circuit modeling, we demonstrate that the approach may provide an insight into the actuator’s physical thickness in a finished printhead product and can be used as an alternative method to assess the effectiveness of the precision manufacturing processes by determining dimensional variance.
