Abstract
Apparatus and methods are described for controlling the positioning of a document relative to a read head in a document processing system. A pressure applying element urges the document against the read head. A speed measuring element rotated by the pressure applying element transmits, to the processing system for use in processing the document, data describing document speed sensed by the pressure applying element at the read head. Distance is eliminated between the read head and speed sensing element, thus eliminating or reducing speed feedback data inaccuracies. Because pressure is applied to the document directly at the read head, read error rates are further reduced.
