Adjusting the Ribbon
When using narrow-width ribbons or very specialist thermal ribbon material,
it may be necessary to adjust the ribbon tension and ribbon balance
adjustments to avoid ribbon wrinkle or slippage.
Ribbon Tension Adjustment
The ribbon tension has three adjustment positions on both the feeding side
(back side) and winding side (front side).

Setting the Ribbon (p.26)
First make a test print and then adjust the printer as required:
• Slippage of the ribbon causes a dirty film to be seen on the media.
Reduce the tension adjusters
• Ribbon wrinkle (diagonal lines across printout): Increase the ribbon tension.
After making any adjustments, print another test print or two to make sure
the ribbon is feeding correctly.
