ABSTRACT:
An electrophotographic printing machine in which two original documents are supported on the platen of an exposure station. Both original documents are flash illuminated to record an electrostatic latent image on a photoconductive surface. One-half of the electrostatic latent image is erased. In this way, one of the original documents is reproduced on a copy sheet. During the next successive machine cycle, a second electrostatic latent image corresponding to both original documents is recorded on the photoconductive member. The other half of the electrostatic latent image is erased and a copy formed corresponding to the other original document.
