Abstract
An imaging apparatus including an imaging system and an optical sensor for detecting a print medium within a paper path. The optical sensor may include at least one light emitter and at least one light detector. The light detector is configured to output two or more light intensities sequentially onto the paper path, which reflects from the paper path or transmits directly onto the optical sensor. Data indicating an amount of light received by the at least one light detector is received by the controller, which performs data analysis to determine the presence or absence of a print medium in the paper path.
