Method and system for feeding and transporting documents

1. Field of the Invention A system and method for feeding and transporting documents are provided. The system includes a feeder stage including a hopper, a feeder and a separator. The hopper includes a hopper wall extending toward the feeder with a waterfall step along the hopper wall and with the stack of documents engaging the hopper wall including the waterfall step to form a pocket area over a limited distance extending from the waterfall step along the hopper wall toward the feeder. A photo edge detector located in the pocket area faces the stack of documents such that when a feeding document trailing edge passes the waterfall step, the trailing edge is detected by the photo edge detector while in the pocket area. The system further includes a transport stage downstream of the feeder stage for receiving the fed documents.
