Document imaging system and method for imaging documents

An apparatus for processing documents, comprising:

• a feeder operable to receive a packet of a plurality of documents and separate the documents to serially feed the documents away from the feeder, wherein the feeder comprises a roller or a belt and an entry gap having a thickness between the roller or the belt and an opposing surface;
• a sensor for detecting a characteristic of the documents in the packet indicative of whether the number of documents in the packet exceeds a predetermined threshold;
• a pre-feeder for feeding the packet of documents into the entry gap of the feeder;
• a controller configured to control the pre-feeder in response to data received from the sensor, wherein in response to receiving data from the sensor indicative of the number of documents in the packet exceeding a first threshold the controller is configured to control the pre-feeder to drive the packet a first distance into the entry gap;
• and wherein in response to receiving data from the sensor indicative of the number of documents in the packet exceeding a second threshold the controller is configured to control the pre-feeder to drive the packet a second distance into the entry gap.
