Abstract
This is a system to coat oil on a fuser roller in a xerographic marking procedure. The system has an IR sensor which is located adjacent to the metering roller and which measures the emissivity of an oil film on the metering roller. Once the IR sensor determines the emissivity of this film, it conveys the emissivity reading to a controller. The controller then controls the metering roller speed to thereby control the oil film thickness. Once a fixed oil film is determined, the emissivity can be used to ensure this same film thickness is applied from run to run. There is no need to redesign the entire oil coating apparatus when the desired film thickness is varied, the same apparatus is used only the emissivity will vary to vary the oil film thickness.
