ABSTRACT:
An electrostatographic reproduction apparatus for producing copies of an original document on copy sheets includes a mechanism for determining the size of the original document. The document size determining mechanism includes an optical document scanner, logic and control means and an advanceable multi-section document cover belt. The multi-section belt has a white section and a dark section which are selectably advanced over a document so as to create a color contrast between the color of the document and the color of the selected document cover forming section.
