Abstract
An auxiliary ribbon separator for use on a dot-line printer is positioned to prevent vertical ribbon displacement in the presence of upward forces such as caused by perforations on continuous feed paper. The auxiliary separator is located so that the ribbon is guided past an end of a front yoke. The front yoke serves as a course ribbon guide and is a component of the electro-magnetic assembly of the print head associated with the printer. The auxiliary separator may be shaped so as to facilitate loading of the ribbon in the printer.
