DETERMINING A HEALTHY FLUID EJECTION NOZZLE |
| 摘要 |
A method of determining a healthy fluid ejection nozzle includes measuring changes in impedance across the nozzle as fluid passes through it. A printhead includes a metal probe that intersects an ink nozzle and an integrated circuit to sense a change in impedance across the nozzle through the metal probe.
