    Abstract

    Although the identification of printwheel typescript is predicated on the characteristics of the typing system, most of the identifying defects encountered are normally ascribed to the printwheel. Typescript samples from several new printwheels of different manufacture were examined to ascertain whether class defects are present in printwheel typescript. It was found that several different types of class defects commonly occur in typescript samples of new printwheels. These class defects often appear similar to individual identifying characteristics, when in fact, they are indicative of an entire group of printwheels.
