A multi-functional device is provided to allow a scanning sensor to read a manuscript or detect a color registration of an image formed on an image transfer belt. A printing unit(110) includes an image transfer belt(143) on which a plurality of colors overlap to form a color image. A scanning unit(190) reads a manuscript with a scanning sensor to input an image. The scanning unit is mounted within the printing unit and the scanning sensor is rotatably installed. When the scanning sensor reads a manuscript, it is rotated toward the manuscript. When the scanning sensor detects a color registration, it rotates toward the image transfer belt. The scanning unit includes a path guide unit for selectively changing a transfer path of a manuscript or a print media when the manuscript is read or a sheet of print media is supplied to the printing unit. The path guide unit is rotated by a driving unit(195). A scanning sensor(196) which can be movable is prepared at an upper part of a frame(191) to read an original document and detect a color registration of an image transfer belt(143).
