After adjusting parallelism and no even strong pressure exists over
the complete print width, by means of a plate (C, Figure 14) you can
set the balance as follows:
1. Loosen screw (D, Figure 14) about one quarter turn.
2. Turn the eccentric bolt (E, Figure 14) to adjust the pressure
balance.
Adjust the balance as long as the printing result comes up to your
full expectation.
3. Fasten again the screw (D, Figure 14).
4. Start a print order with approx. 10 labels and control the correct
passage of transfer ribbon
Increasing the head contact pressure leads to an improvement of the
print image density on the corresponding side and to a shifting of the
ribbon feed path in the corresponding direction.
CAUTION!
Damage of printhead by unequal use!
⇒
Change factory settings only in exceptional cases.
The selection of the smallest value can optimise the life cycle of
printhead.
1. Turn the pressure screws (A, Figure 14) to change the pressure of
printhead.
2. Turning the pressure screws (A, Figure 14) as far as they will go
in clockwise direction results in a pressure increase of 10N in
contrast to the factory setting.
3. Turning the pressure screws (A, Figure 14) exactly one rotation
from the right stop position counter clockwise results in the factory
settings.
It is importantly that the knurled button which is coated with
protective lacquer is not removed from the pressure screw as
otherwise the above mentioned settings are faulty.
