1. A fluid dispensing system, comprising:
a photon source disposed on a moveable carriage; and
a fluid ejector array having a plurality of fluid ejection elements disposed on a substrate, each fluid ejection element having:
a fluid ejector, and
a photodetector electrically coupled to said fluid ejector, wherein moving said photon source over at least a portion of said fluid ejector array, selectively illuminates photodetectors, thereby selectively activating fluid ejectors coupled to illuminated photodetectors.
