ABSTRACT:
A photoreceptive unit and transfer unit replacement system of a printer includes a door opening and closing an entrance formed above a portion where a photoreceptive unit and a transfer unit are installed in a main body of the printer. A first guide rail is provided at a frame of the main body to guide the photoreceptive unit which enters through the entrance and descends. A second guide rail is provided at the frame to guide the transfer unit which enters through the entrance and descends. A locking unit locks and unlocks the photoreceptive unit and the transfer unit according to an operation of opening and closing the door. Thus, since the operation of opening and closing the door are performed according to the operation of locking and unlocking the respective photoreceptive unit and transfer units, and the photoreceptive unit and transfer units pass through the entrance disposed above the units, a replacement process can be performed more conveniently and stably.
