ABSTRACT:
A method and apparatus for preventing persons from leaving original documents in a document copier. A document is scanned by a document copier to produce a stored image thereof. Prior to producing any copies of the document, it is determined whether the document has been removed from the document copier. Producing any copies of the document is withheld unless it is determined that the document has been removed from the document copier. Alternatively, the stored image of the document may be examined to determine whether it includes selected information. If the stored image of the document includes the selected information, producing any copies of the document is withheld unless it is determined that the document has been removed from the document copier.
