Abstract

Disclosed is a sensing method and apparatus for detecting and measuring toner exiting from the cooling rolls downstream from an extruder in a toner manufacturing process. An infrared sensor, for example, capable of scanning a toner web transport belt for the width, thickness, and temperature, of the toner mass thereon, enables the detection of unusual or irregular operation. The toner mass parameters are monitored and an alarm is signaled if the toner parameters stray beyond specified limits. The manufacturing process can then be halted or operational parameters, for example temperature of the cooling rolls or the rate of extrusion, can modified or adjusted accordingly to return the process to within specified operational ranges.
