  • Document processor having improved throughput capabilities
    Patent number: 5121915
    Abstract: A document processor having closed loop control of the average feeding rate of the documents and closed loop control of the gaps between documents and dynamic control of the removal of documents from the input station. By controlling the rate at which documents are introduced into the system, and the gaps between documents, more documents can be effectively read and processed in a unit of time without exceeding system limitations imposed by hardware (such as closeness of adjacent documents) even as the mechanism changes due to wear or environment.
