Identification of Photocopiers from Fusing Roller Defects

CODEN: JFSCAS

Abstract

A sampling of 27 photocopiers using the indirect electrostatic process were examined for fusing roller damage of significance to the document examiner. Distinctive indentation patterns were present on some copies produced, which were sufficient for identification and for establishing that the copies had been in physical contact with the copiers. The frequency and nature of the fusing roller defects observed is described.
