Abstract
During a liquid spray pattern detection procedure, the sensor (50, 52) is operable to detect the presence or absence of an edge of the dispensed liquid spray pattern. The nozzle (18) of the liquid dispensing system is moved to a predetermined position (A) relative to the sensor (50, 52) to determine the presence or absence of the spray pattern and is then moved to a second predetermined position (B) relative to the sensor (50, 52) to again determine the presence or absence of the spray pattern. Based on these determinations, the width of the spray pattern can be verified. This provides a quick means to verify that the width of the dispensed pattern is within certain tolerances.
