Abstract
A method of cleaning a dispenser including a faceplate, comprises emitting light over the surface of the faceplate across the width of the faceplate, measuring an intensity of the light at a plurality of points on the surface of the faceplate after the light has passed over the width, determining, based on the measured light intensity, whether an amount of accumulated formable material on the faceplate is greater than a predetermined value, and in a case that the amount of accumulated formable material is greater than a predetermined value, imparting a suction force on the surface of the faceplate using the vacuum at a distance from the faceplate to remove at least a portion of the accumulated formable material from the surface of the faceplate.
