An electrophotographic printer including at least one paper feeder, a printing unit, a feed roller, and an overhead projector paper detector. The at least one paper feeder loads recording media. The printing unit transfers a toner image formed according to an electrophotographic method to the recording media fed from the paper feeder and applies heat and pressure to the recording media so that the toner image is fixed and fused to the recording media. The feed roller is installed between paper feeder and the printing unit and advances the recording media fed from the paper feeder to the printing unit. The overhead projector paper detector is installed between the feed roller and the printing unit to determine whether the recording media are OHP papers. Accordingly, even though recording media are fed from a plurality of cassettes, only one OHP paper detector can detect OHP papers.
