INTERLOCKING CONTROLLING METHOD OF ELECTROPHOTOGRAPHIC DEVICE

摘要

PURPOSE:To make it possible to realize smooth interlocking action among a plurality of electrophotographic devices in comparatively complicated printing operation. CONSTITUTION:A means for forming sign 5 corresponding to the content of image information on printing paper P is provided in an electrophotographic device 1, which is provided in the upperstream of image forming process. In a downstream electrophotographic device 2, a means 6 for recognizing the sign 5 is provided so as to actuate the downstream electrophotographic device 2 by the sign 5.
