Abstract

A system and related methods for automatically identifying media type in a printing device media tray is presented. The system comprises a controller, and an optical sensor, communicatively coupled to the controller, wherein the sensor is positioned to locate and identify a code containing media type information from a next available piece of print media, and to generate a signal to the controller based, at least in part, on the identified code.
