A method or system of automatically interleaving duplicate sheets or blank sheets in between each copy, particularly for transparency copies. In response to operator selection of a "transparency" or "interleave" feature on the control console or screen, the copier would automatically "dual flash" a document (or print two identical electronic input images on the photoreceptor) and automatically switch to a copy sheet mode feeding alternately from the main copy sheet tray and the auxiliary copy sheet tray (with transparencies in one and plain paper sheets in the other), to sequentially produce two copies in the same processor on two different media so that at the copy output stack mylar transparencies could be protectively separated from one another by regular (paper) copy sheets which also have a duplicate of the image. Alternatively, the interleaved sheets may be blank depending on the operator selection. The only UMC cost would be that of the additional display and control software - no additional hardware is required. Accordingly, this is an appropriate feature for highly featured copiers, particularly those already equipped to provide cover inserts at the beginning and end of the document set by switching between two different paper supply tray feeders. *
