Abstract
The invention relates to an imaging system for a multi-magnification copier which employs a plurality of gradient index lens arrays to provide a 1.times. as well as a magnification capability. The magnification range of the copier is extended beyond the discrete value associated with each lens array by changing the speed at which the document is normally scanned in the isometric mode so that the image is anamorphically magnified in the scanning direction. This magnification either enlarges or compresses the image at the imaging plane and, due to the narrow scan slit employed with gradient index lens arrays, retains adequate resolution in the developed image.
