ABSTRACT:
Machine for marking documents with visually readable printed information on one portion of the document, and with magnetically encoded information on another, magnetizable portion of the document. The magnetically encoded information is read to determine if it was recorded with an error. If it was, printing is prevented so that a document which has an error in the magnetically recorded information is presented as a blank, non-printed document. It is therefore readily apparent that the document is defective and should not and cannot be used.
