An electrophotographic printing method and apparatus in which a variable magnification optical system adjusts the size of indicia being reproduced on a copy sheet from a document. The size of the surface area of the copy sheet is compared with the surface area of the document being reproduced to generate a signal indicative of the difference therebetween. Responsive to this signal, the platens supporting the document and a lens are moved in synchronism relative to the photoconductive member to adjust the magnification of the indicia being reproduced. |
