1. A method of processing a plurality of page images belonging to a plurality of documents so as to separate, without the use of separator sheets, the page images into individual ones of the plurality of documents, the method comprising: receiving the plurality of page images from a scanner; extracting content from each of the plurality of page images; for each of the plurality of page images, determining, based upon the extracted content, whether the respective page image is an initial page image of one of the plurality of documents, wherein the determining comprises: assigning a classification weight to each of the plurality of page images based upon an analysis of the extracted content, wherein each classification weight reflects a discrete probability that the respective page image is one of the initial pages of one or more of the plurality of documents; and determining, based upon a comparison of the assigned classification weight to a sample set of classification weights, whether the page image is an initial page of a document in the plurality of documents; wherein the comparison comprises calculating a percentage probability of whether the page is an initial page of one of the plurality of documents according to a formula: 
 (1−(( W type X −W Assigned )/ W type X )); wherein W type X is a classification weight of a page of a document of a particular type in a sample set of documents; and wherein W assigned is the classification weight assigned to the page image; and appending each of the plurality of page images located between a first determined initial page image of the one of the plurality of documents and a subsequent, second determined initial page image of another of the plurality of documents to the first determined initial page image.
