METHODS OF OPERATING AN IMAGE-BASED CHECK PROCESSING SYSTEM TO DETECT A DOUBLE FEED CONDITION OF CARRIER ENVELOPES AND AN APPARATUS THEREFOR

摘要

A method is provided of operating an image-based check processing system to detect a double feed condition of carrier envelopes. The method comprises attempting to read a magnetic ink character recognition (MICR) codeline from a first predefined area of an image of a document item. Based upon the attempted read of a MICR codeline from the first predefined area of the item image, a determination is made if the document item is a carrier envelope. A conclusion is made that the document item is not a double-fed item when a determination is made that the document item is a carrier envelope. A conclusion is made that the document item is potentially a double-fed item when a determination is made that the document item is not a carrier envelope. The method may further comprise attempting to read a MICR codeline from a second predefined area which is different from the first predefined area of the item image. Based upon the attempted read of a MICR codeline from the second predefined area of the item image, a determination is made if the item image has a valid MICR codeline. A conclusion is made that the document item is not a double-fed item when a determination is made that a valid MICR codeline has been read from the second predefined area of the item image. A conclusion is made that the document item is potentially a double-fed item when a determination is made that a valid MICR codeline has not been read from the second predefined area of the item image.
