Mobile device with dual optical sensing pathways

摘要

A mobile device having an internal printer is disclosed. A media path is provided for receiving a print medium and a media drive mechanism transport the print medium along the media path past a printhead of the printer. An optical sensor and two separate optical pathways are also provided. The first optical pathway allows the optical sensor to image a surface of the print medium in the media path. The second optical pathway allows the optical sensor to image an area external to the mobile device.
