History Of Use
A spirit duplicator (also referred to as a Ditto machine in North America, Banda machine in the UK or Roneo in France and Australia) was a printing method invented in 1923 by Wilhelm Ritzerfeld and commonly used for much of the rest of the 20th century. The term "spirit duplicator" refers to the alcohols which were a major component of the solvents used as "inks" in these machines. The device coexisted alongside the mimeograph. Spirit duplicator technology gradually fell into disuse starting in the 1970s after the availability of low-cost, high-volume xerographic copiers. (Source: Wikipedia, "Spirit Duplicator", accessed November 2017). Likely used by the School District to create copies of documents for use by students (handouts, tests, etc.).
