Abstract: A bottom vacuum corrugated feeder (BVCF) includes a tray for supporting a stack of documents. The tray is angled downhill relative to the feeding direction of the documents such that the leading edge of the stack is urged to a common stop member. The tray also includes a single side guide for aligning one side edge of the stack. A stack height sensor sends a signal corresponding to stack height to a controller which in turn controls voltage to be applied to a DC motor controlled blower based on a predetermined ratio of air flow pressure to stack pressure. The structure enables intermixed size document feeding in a BVCF.
