Abstract
Crosstalk in a piezo printhead is reduced by storing a coefficient that expresses an amount of crosstalk between a first nozzle and an adjacent nozzle. A drive waveform voltage is pre-biased using the coefficient, and the pre-biased waveform is applied to a piezoelectric material of the first nozzle.
