Abstract
A document reproduction machine having a multiple range of magnifications employs a scanning optical system which is controlled as to scanning speed and distance of travel by the selected magnification using a three-dimensional cam mechanism. In the higher reduction copying ranges the speed of the scanning optical system is automatically increased in proportion to the selected magnification reduction, and the increase in scanning distance is tailored to match expected document size to achieve a minimum amount of scanning distance.
