Abstract
A document processing system includes a document track composed of a pair of opposing rigid track walls. The documents are moved along the document track in a series to allow operations to be performed on the documents. An apparatus for detecting a document with an attachment includes a strike plate formed by a separate section of a wall of the document track. A magnet is arranged to attract material toward the strike plate. An accelerometer is mounted to the strike plate. The accelerometer detects an impact of an attachment to the strike plate when a document with an attachment passes the strike plate.
