Trigger
The BC5100 scanner uses the LA 650 trigger (photocell) to begin and end
the scan cycle. The LA 650 trigger uses a red laser beam to detect
substrates. The trigger signals the system to begin the scan cycle when it
senses the leading edge (or some other selected edge) of the product. The
scanning cycle continues until the trailing edge (or some other selected
edge) of the product is sensed.
