Claim 5:
6. A conformal coating machine having a dispensing control system for controlling a width of a spray pattern exiting a dispenser, the dispensing control system comprising:
a sensor for measuring an actual width of the spray pattern, the sensor consisting of a first sensor portion and a second sensor portion that faces the first sensor portion, the sensor coupled to a frame component within the conformal coating machine, the first sensor portion configured to emit a beam of light having a width greater than the width of the spray pattern; and
at least one adjustment component in operable communication with the dispenser;
wherein the spray pattern that is unaltered after exiting the dispenser is measured by the sensor based on light not received by the second sensor portion to compare with a desired spray pattern, the measurement occurring without moving the dispenser and the sensor.
