An implementation of a technology is described herein for automatically detecting when multiple sheets of print media are fed into a print device. More particularly, described herein is a technology for indirectly and automatically determining the number of sheets of print media by determining the stiffness of print media, such as acetate and paper. At least one embodiment, described herein, includes a registration assembly of a laser printer. In this assembly, the print medium is deflected (i.e., bent, bowed, buckled, etc.). A measurement of such deflection is made. That measurement is an indication of the relative stiffness of the print medium. Assuming approximately similar densities, the stiffness of print media is directly related to its thickness. The thicker the medium the stiffer it is and vice versa. The thickness of print media is directly related to the number of sheets of print media.
