QLS-4100 X 86
Thermal Transfer Ribbon Tension
The QLS-4100 X features an automatic ribbon tensioning mechanism to ensure
consistent tension from a full to empty ribbon supply roll. Normally, a manual
ribbon tension adjustment is not required. However, if you notice film wrinkling or
one of the colors smudging, you can adjust the tension to alleviate these condi-
tions.
• If film is wrinkling on a station, turn the knob on the ribbon supply mandrel
clockwise to increase the tension.
• If ink is smudging at a station, turn the knob on the ribbon supply mandrel
counterclockwise to decrease the tension.
Ribbon wrinkling may also be alleviated by adjusting the eccentric at the end of
the ribbon guide shaft located at the lower, rear section of the print station. Loosen
the screw securing the shaft and using a wrench, turn the eccentric until wrinkles
have been eliminated then retighten the screw to secure the shaft.
