ABSTRACT:
Copy production machine, such as a xerographic copier, includes an original document feed mechanism which is responsive to insertion of the document to place the document automatically in an imaging position. The copy production machine is actuated by the document feed mechanism to produce one or more copies of the placed original document. An original document being entered into imaging position may be removed by an operator or by the automatic original document feed mechanism, whereby the copy production machine is inhibited from producing copies until the original document is either reinserted or another original document is inserted. Thereupon, copy production resumes in the normal manner.
