Crosstalk reduction in piezo printhead |
| 摘要 |
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. |

1. A method to reduce crosstalk in a piezo printhead comprising:
storing a coefficient that expresses an amount of crosstalk between a first nozzle and an adjacent nozzle; pre-biasing a drive waveform voltage using the coefficient by summing to the drive waveform voltage, a scaled copy of a second drive waveform voltage for the adjacent nozzle; and applying the pre-biased drive waveform voltage to a piezoelectric material of the first nozzle. |
