ABSTRACT:
A method of media type differentiation includes the steps of providing a media sensor including a specular detector that provides a specular signal output having a signal level related to an amount of the reflected specular light received; providing a highly reflective surface positioned to face the media sensor; interposing a print media sheet between the media sensor and the highly reflective surface; using the media sensor to measure a first amount of the reflected specular light and determining a first signal level of the specular signal output of the specular detector; and using the first signal level to differentiate the print media sheet as being one of a transparency media sheet or a high glossy media sheet.
