Image forming apparatus having optical sensor system, optical sensor system having heating module for removing deposit formation of volatile organic compounds there from, and method thereof

摘要

An optical sensor system is disclosed including a source module, a detection module, and a heating module. The source module includes a source housing unit having a source window member to emit a detection signal through the source window member. The detection module includes a first detection housing unit having a first detection window member spaced apart from the source module. The detection signal received by the detection module corresponds to an amount of volatile organic compounds (VOC) present in a path of the detection signal between the detection module and the source module. The heating module heats the source window member and the detection window member to remove deposit formation of the VOC there from.
