Abstract
A document feeder is provided for feeding documents along a document feed path. The document feeder comprises a tray for containing a stack of documents to be fed along the document feed path. A picker mechanism is provided for picking a document from the stack of documents stored in the tray and moving the picked document along the document feed path. A sensor mechanism is provided for (i) detecting movement of documents along the document feed path, and (ii) providing an output signal indicative thereof. A controller responsive to the output signal from the sensor mechanism is provided for controlling operation of the picker mechanism to provide a gap of at least a predetermined size between adjacent documents moving along the document feed path.
