Abstract

The identification of office copier machines has been simplified by the computerization of their class characteristics. The class characteristics examined are paper type, type of toner, reduction/enlargement capabilities, paper supply, presence of identifying marks, fusion method, and color capabilities. These known class characteristics are then compared against the established data base to limit the search to the possible manufacturers.

Keywords:
questioned documents, photocopiers, classifications, fusion method, photocopy
