Method and apparatus to reduce variation of physical attribute of droplets using performance characteristic of dispensers

A performance monitor determines a performance characteristic of a plurality of dispensers receiving fluid from a reservoir. Each of the plurality of dispensers has an actuator that, when actuated, causes the each of the dispensers to generate a droplet of the fluid. A driver generates a drive comma...

Zusammenfassung:	A performance monitor determines a performance characteristic of a plurality of dispensers receiving fluid from a reservoir. Each of the plurality of dispensers has an actuator that, when actuated, causes the each of the dispensers to generate a droplet of the fluid. A driver generates a drive command to the actuator to adjust a physical attribute of the droplet based on the performance characteristic to satisfy a performance criteria.
