| 主权项 | 1. A method for determining an issue in an inkjet nozzle with impedance measurements, comprising: taking a first impedance measurement to detect a presence of a drive bubble with an impedance sensor coupled to an interior surface of an ink chamber; and taking a second impedance measurement to detect said drive bubble with said impedance sensor after said first impedance measurement. | ||
