  • Calibration of platen registration edges in copiers
    Patent number: 4933778
    Abstract: An electrophotographic copies having a document scanner which determines the location of registration marks on the platen. The scanner is initially operated in a calibration mode without a document on the platen. The platen is scanned and the data obtained is processed to determine when transitions from low to high density occur. These occurrences are translated to scanner locations to obtain the locations of the edges of the registration marks or guides, and the locations are stored in memory. In subsequent scannings of documents, only data within the determined locations of the registration edges is stored in memory.
