<p>A copier (10) has the capability to determine the size of the original document, or a designated portion thereof, for purposes of auto scaling, auto paper select, and/or window scaling, to set image magnification parameters, and to process the image signal according to the set parameters in but a single scan of the original document. The copier forms an image on a copy sheet based on a supplied series of electrical data signals. Document recognition (38) determines the size of an original document from a series of electrical data signals, and a series of electrical data signals representative of the image content of a document is stored in memory (34). The size of a copy sheet and the size of the formed image are matched in accordance with the document recognition in response to but a single scan (28) of an original document. A portion of an original document and a magnification ratio may be designated for scaling.</p> |
