A document feeding device includes a pressing member that extends in a document conveying space from a document conveying surface of an outer conveying guide member having a counter conveying roller, of two conveying guide members provided in a first document conveying path such as to oppose front and back sides of a document, toward a document conveying surface of an inner conveying guide member. The method provides the steps of electronically monitoring network user compliance with a network security policy stored in a database, electronically evaluating network security policy compliance based on network user compliance, and electronically undertaking a network policy compliance action in response to network security policy compliance. A soluble base is then added to the pretreated lignocellulosic feedstock to adjust the pH and produce a neutralized feedstock.
