The setting has to be adjusted in the following cases:
•
If the printing image is too pale on the left side, turn the head pressure adjusting wheel to a lower
number.
•
If the printing image is too pale on the right side, turn the head pressure adjusting wheel to a higher
number.
•
When using narrow tapes:
In this case, the spacing between print head and roller can be so small that they rub against each other.
To prevent this, turn the print head adjusting wheel to a lower number to reduce the pressure on the
right side of the print head.

3.7 Adjusting the ink ribbon tension
The printer automatically keeps the ink ribbon taut during printing.
It may be necessary to adjust the tensioning system for narrow ribbons.
On the side of the print head there is a vertical and a horizontal oblong hole where you can adjust the ink ribbon
tension as shown in Fig. 3-9.
Settings:
Ink ribbon up to 100 mm wide: strong
Ink ribbon up to 75 mm wide: medium
Ink ribbon up to 50 mm wide: weak
