Indentations Produced by the Document Feeder Mechanisms of Two Black and White Photocopiers
By: Larry A. Olson
Abstract
Recent casework revealed that indentations found on a questioned document could be associated with a photocopier’s document feeder. This research was undertaken to analyze indentations produced on original documents by the document feeders of 2 black-and-white photocopiers. The copiers, located at the IRS National Forensic Laboratory, were of the same make and model. The goals were to determine what indentations occurred in both single- and double-sided copy modes and whether they exhibited any class, or even individual, characteristics.
