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.

A fluid dispenser calibration system includes a fluid dispenser having a plurality of nozzles, a balance having a balance surface, and a mask positioned between the fluid dispenser and the balance surface. A nozzle pitch is a distance between two adjacent nozzles. The balance measures mass of fluid dispensed from a single nozzle and measures a change in mass on the balance surface. The balance surface has a linear dimension that is greater than the nozzle pitch. The mask includes an aperture and a catch region. The aperture allows fluid dispensed from the single nozzle to impact the balance surface. The catch region catches fluid dispensed from remaining nozzles in the plurality of nozzles.
