Printable media sensing devices, systems and methods are disclosed herein. An array of light emitters projects light through a printable media sheet for detection by a corresponding array of light sensors. A processor is operably connected to the array of light emitters and light sensors, and is configured to activate the light emitters, and receive output signals from the light sensors, and permit the accurate detection and determination of the locations of top of form (TOF) and bottom of form (BOF) for a given printable media sheet, as well as multiple widths corresponding to such sheet. According to some embodiments, the locations of labels on a sheet may also be detected with heightened accuracy, as may regions having no labels disposed thereover.
