ABSTRACT:
Automated quality control is provided in a document conversion system. A scanner scans and converts printed documents into digital data. A computer stores the digital data into one or more files which are then displayed on a monitor for view by an operator. The computer obtains from the operator an error count of conversion errors observed by comparing the printed documents scanned to the diplayed files. The computer calculates a conversion accuracy percentage based on the number of conversion errors.
