    Abstract

    The IBM Correcting Selectric typewriter was introduced 1 April 1973. It was a new dimension in typewriter history and a product that many wished had been conceived of years ago. The Correcting Selectric uses two types of ribbon systems: a Correctable Film ribbon with lift-off tape and a Tech III ribbon with cover-up tape. This paper is concerned with the former ribbon system because of the unique manner by which a typewriting error is corrected. The mechanical operation of the machine remains the same with both ribbon systems.
