Abstract

Converting related defects in paper account for about 60 to 70 percent of all complaints by paper customers. Manual inspection of finished reams is a laborious task which is prone to human error. This manual inspection process can be replaced with an automated process in which individual sheets of paper from a sample ream are fed through a high speed xerographic engine that has been internally retrofitted with a high speed video camera and related software. The sheets are scanned for converting related defects and data are acquired and processed by computer.
