Abstract
A method of inspecting a dispenser including a faceplate comprises translating a sensor across the faceplate while measuring a distance between the sensor and the faceplate. The sensor is oriented such that a longitudinal axis of the sensor extends at an acute angle relative to a longitudinal axis of the faceplate. The method may include translating another sensor across the faceplate while measuring the same distance. Or the method may include another translating of the sensor across the faceplate while measuring the same distance. In either case, the sensor is oriented such that the longitudinal axis of the sensor extends at an obtuse angle relative to the longitudinal axis of the faceplate. The method includes determining, based on the measured distances, whether an amount of accumulated formable material on the surface of the faceplate is greater than a predetermined value.
