Abstract
The scanning drum of a facsimile receiver carries a longitudinally extending stripe such that portions of the stripe at opposite extremities of a document carried by the drum are exposed. The width of the stripe at the exposed portion adjacent the leading edge of the document is sensed by an optical sensing head and stored in memory prior to transmitting dark/light variations in the document. The scanning of the document continues until the optical scanning head is juxtaposed to the exposed portion of the drum adjacent the trailing edge of the document. At this time, the width of the stripe is again detected and compared with the width in memory so as to verify that the scanning of the document is complete. The facsimile transmission is then terminated.
