Abstract
A system for identifying a characteristic of a printing media includes a light source module that has a light emitting diode (LED) and an aspheric lens and a light detection module that has a photodetector and an aspheric lens. The light source module and light detection module are oriented with respect to a printing media such that the focusing points of the respective aspheric lenses are located at a common position on the printing media. The system differentiates between printing media types by applying light to the surface of the printing media and measuring the light that is reflected from the surface.
