Fluid ejection devices and methods thereof

摘要

Fluid ejection devices and methods thereof are disclosed in the present disclosure. A method includes establishing fluid communication between an ejection chamber and a fluid supply chamber of the fluid ejection device such that the ejection chamber includes a nozzle and an ejection member to selectively eject fluid through the nozzle. The method also includes detecting at least one impedance in the fluid by a sensor unit having a sensor plate.

主权项

1. A fluid ejection device, comprising:
a fluid supply chamber to store fluid; a plurality of ejection chambers including nozzles and corresponding ejection members to selectively eject the fluid through the respective nozzles; a channel to establish fluid communication between the fluid supply chamber and the ejection members; a temperature adjustment module to establish at least one temperature of the fluid of the fluid ejection device; and a sensor unit having a sensor plate, the sensor unit to detect at least one impedance in the fluid corresponding to the at least one temperature;
wherein the sensor unit detects a plurality of impedances in the fluid corresponding to the at least one temperature at predetermine time periods.
