In cartridge ribbon restraint systems, a single strand of ribbon is drawn out of the cartridge and passes in front of a print head at a prescribed tension to provide for a proper transfer of ink from the ribbon to the paper without smudging. The tension on the ribbon must also allow for ribbon control functions such as shifting the ribbon vertically to access different color bands in a multicolor ribbon. High tension or non-uniform tension can cause a failure in ribbon movement.
