ABSTRACT:
A method of controlling a micro fluid ejection device by sensing a middle zone temperature, and selectively applying an amount of power to a middle zone heater to achieve a target temperature. An edge zone temperature is also sensed and power is selectively applied to edge zone heaters to achieve a target temperature for the edge zones, whereby uniform ejection of fluid droplets along an ejector array may be achieved.
