Documents Produced Using Office Technology
Michael John Allen · 2015
This chapter focuses on the ways in which the written word is put on paper by means of mechanical devices. In order to explain how a forensic examination of documents produced with such devices is made, the chapter first discusses the mechanisms of the machines themselves. The mechanisms together with the inks used dictate what the output looks like on paper. The chapter then focuses on the avenues of forensic evidence that can determine which kind of mechanism was involved in the production of a document. Interpreting evidence in cases involving typebar typewriters is based on the experience of the document examiner. Typewriters, computer printers and copiers of various kinds are pieces of machinery that are, to varying degrees, familiar to large sections of the public in general and professional people in particular as they are tools of the trade for many people.
