Blow Tube and Support Air Adjustments
The blow tube must be adjusted in such a way that the label takeover is unhindered by turbulence and the supporting
air blows the label evenly against the pad.
The default factory value is 2 bar.
i
Note!
When changing the label size (2", 4" or 6") the appropriate blow tube is to be used. When changing the label
size check the number of holes needed to support the entire label and set the supporting air respectively.

Adjusting the blow tube
The blow tube (4) supplying the supporting air can be rotated around its axis. That way the direction of the supporting
air can be optimized.
1. Loosen screw (1).
2. Put in the blow tube (3) into the tube adapter B (2).
Turn the blow tube (3) in the direction, that the air current supports the take up of the label from the dispensing
edge (5) of the pad.
•
For smaller labels direct the air current toward the dispense edge (4) of the printer.
•
For larger labels direct the air current away from the dispense edge (4) .
Use the graduation to orientation.
3. Tighten screw (1).
4. Remove as many rings (6) as needed to allow the supporting air to blow on the entire label width
.
