<p>An electrophotographic printing machine of the type having a variable magnification optical system (17), which adjusts the size of indicia being reproduced on a copy sheet from a document. The magnification of the optical system (17), is controlled so as to reproduce the indicia of the document on the copy sheet. The machine includes means (38) for comparing the size of the surface area of the copy sheet with the surface area of the document and generating a signal indicative of the difference therebetween; and means (72) responsive to the signal from said comparing means, for controlling the optical system to adjust the magnification thereof so as to reproduce the indicia of the document on the copy sheet. A method of reproducing an original document on a copy sheet is also disclosed.</p> |
