Chapter 4 Media (Paper) and Ribbon
Ribbon tension adjustments
The ribbon tension should be adjusted as needed according to the media (paper) width to prevent ribbon from slackening or wrinkling. To increase tension torque, turn the source ribbon bobbin (the deeper side viewed from the front of the printer) knob clockwise until the required number is obtained from the scale, while stopping the gear with a coin inserted in the slit on the ribbon bobbin support and held down. Generally, the wider the ribbon is, the larger the ribbon tension is. Always maintain a constant tension of the source ribbon bobbin.
