Abstract

The following disclosure proposes the use of two different colored LED light sources to alternately illuminate original or copy sheets within a reprographic system, and using appropriate electronic circuitry, to automatically identify the approximate color of the paper. Such an approximation may be used to adjust the scanning of such documents, or to alert operators of the presence of colored stock in a paper tray.
