ABSTRACT:
An electrophotographic copying machine includes a housing which is separated into an upper body and a lower body along a path of a copy paper in order to facilitate the removal of a jammed paper. When the housing is separated into the upper and lower bodies, a light memory effect is created on a photosensitive drum due to the ambient light. When the upper body is closed after removal of the jammed paper, a light memory removing operation is conducted, wherein a transcription unit and an erase unit are activated without transferring a copy paper.
