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.

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.
