  • Double document feed detection for a document handler in a reproduction machine
    Patent number: 4153241
    Abstract: A control system for a document handler in a reproduction machine. As the document handler transports a set of originals to an exposure platen, a counter is incremented and stores the total number of documents placed on the platen for the set. If it is desired to recycle the set to the platen again, the machine compares the document totals for each set cycle to insure that they are the same thereby checking for erroneous double document feeds.
