Abstract
Systems, methods, and apparatuses are disclosed for sensing clear or transparent media in printers. In one embodiment, a media conveyance apparatus is provided comprising a light sensor positioned on a first side of a media conveyance path; a light source positioned on a second side of the media conveyance path; and presence determination circuitry. The media conveyance apparatus is configured such that the light sensor and the light source are positioned such that media may pass between the light sensor and the light source along the media conveyance path. The media conveyance apparatus is further configured such that the light sensor provides signals to the presence determination circuitry indicating an amount of light received from the light source and the presence determination circuitry determines a reflection loss based on the signals received from the light sensor and further determines whether the reflection loss satisfies a loss threshold. The media conveyance apparatus is further configured so that if the presence determination circuitry determines the reflection loss satisfies the loss threshold, the presence determination circuitry outputs a media present indication.
