Abstract

When a mass such as a wire matrix print head, is driven by a drive belt, it is necessary to maintain proper belt tension on the print head drive belt to prevent numerous problems. If the belt tension is too low, the drive system becomes elastic, making speed control difficult, whereby print quality can suffer. Conversely, when the belt tension is too high, excessive friction and short belt life result.
