Fig. 21 Adjust the blow tube
The blow tube (2) for the supporting air can be rotated around its axis. This allows the direction of the supporting air
can be optimized.
1. Loosen screw (1).
2. Put in the blow tube (4) into the tube adapter A (2).
Turn the blow tube (2) in the direction that the air current can support the take up of the label.
• For small labels direct the air current to the dispensing edge (4) of the printer.
• For larger labels direct the air current away from the dispense edge (4).
Use the graduation to orientation.
3. Open as many holes of the blow tube as are needed to cover the label width. Remove rings (4) if necessary.
All holes outside the label width should be covered with the shrink tube rings provided. Once the unneeded holes
have been covered the shrink tube should be shrunk.
4. Tighten screw (1).
