Abstract
The present application is directed to methods and devices for determining the presence of a module and presence of a media sheet in a media path using output signals from a single sensor in an image forming device. One embodiment includes a sensor which may be oriented in a variety of positions through interaction with the module and the media sheet. An algorithm may be used to determine the presence of the module in a module insertion path and presence of the media sheet in the media path based on the position of the sensor.
