Ribbon Tension Adjustment Knob
The Ribbon Tension Adjustment Knob offers 6 levels of tension to adjust for
different widths of ribbon. Turn the ribbon tension knob clockwise and you will
hear a light click sound as the gear changes. The levels increase the tension
from 0 to the tightest at 5. You will hear a louder click when level 0 is selected to
indicate reset.
Note: Use the lowest setting possible for longer print head life.
Print Head Pressure Adjustment Knob
The Print Head Adjustment Knobs are used to fine tune print quality for different
thickness of media. Turning the knobs increases or decreases the pressure on
the media by the print head. The knobs should always be set to the same level. If
setting them to different levels fixes a printing problem you should clean the print
head and consider replacing it.

Print Head Burn Line Adjustment Knob
The Print Burn Line Adjustment Knobs are used to fine tune print quality for
different thickness of media. Turning the knobs adjusts the print head’s burn line
forward or backward as it relates to the platen roller.
Caution: incorrectly adjusting these knobs can lead to poor print quality
and may cause damage to the printer. Proceed with caution.
The print head burn line default is set for general purpose printing media (plain
paper and paper thickness less than 0.20mm). The print head moves 0.7mm for
each 360 degree turn. Poor print quality when using paper thicker than 0.20mm
may be due to the print head burn line not being at the optimized position. To
correct this, increase the head pressure and adjust the knobs counter-clockwise
to move print head burn line forward then print again. Continue to adjust and test
print as necessary until the image is clear.
