Abstract
A media type sensing method for an imaging apparatus includes the steps of changing a light intensity of a light source by changing a drive signal, while monitoring for an output change of a comparator; determining a drive signal value of the drive signal at a point of detection of the output change; and correlating the drive signal value to a specific media type.
