Abstract
A document acceptor includes a document transport path and a multi-function optical sensor disposed adjacent the document path. The multi-function sensor can be operated in one of two or more modes. Depending on the mode in which the sensor is operated, signals from the sensor can be used, for example, to indicate whether a document has reached a particular position, to determine whether the document includes a predetermined pattern, such as a bar-code pattern, or to determine whether an attempt is being made to pull the document out of the acceptor.
