Abstract
1512160 Electrophotographic copying machine INTERNATIONAL BUSINESS MACHINES CORP 1 Dec 1976 [15 Jan 1976] 50151/76 Heading B6C The machine is of the kind comprising a rotary drum having a renewable photoconductive surface in the form of a web the ends of which pass to supply and take-up rollers within the interior of the drum, and in which, after a plurality of cycles, the rollers are operated to renew the exposed surface of the web, e.g. as disclosed in Specification 1,286,100. Additional programmed control circuitry is provided to automatically cycle the copier through a predetermined number of machine cycles, whilst inhibiting the transport of copy sheet material, each time the exposed photoconductive surface has been changed, in order to precondition it.
