Abstract
Apparatus for detecting black band separator documents placed as markers between batches of documents. The apparatus is responsive to four measurements which enable it to determine when a black band document has passed. These measurements relate to changes in the intensity of light transmitted through the document, the length of a black band, length of the document, and the position of the black band on the document.
