VR1/ALIGN. : adjust to make bidirectional printing line up horizontally. Print a pattern with the | character, and adjust so they fall exactly in line. VR2/IMPRES.: adjust if printing is too faint. The book does not describe how this is done, as a worn ribbon will also give faint printing. Selection of Optional Functions * As shipped Switch 2-1
