Spectra II Adjustments, settings and alignments
09.16 Serviceanleitung 35
The form of the CornerType printhead needs the setting of parallelism
in direction of the adjusting angle and in horizontal position. It needs a
little bit of experience to know in which direction you have to adjust the
printhead to receive a high quality printing.
1. Loosen the screws (H or J, Figure 15) with a hexagon key by
approx. ¼ rotations.
2. Adjust the parallelism with the adjusting screws
(G or I, Figure 15).
Clockwise = printhead moves backwards
Counter clockwise = printhead moves forwards
3. Adjust the parallelism as long as the printing result comes up to
your full expectation.
4. Tighten again screws (H or J, Figure 15).
5. Start a print order with approx. 10 labels and control the correct
passage of transfer ribbon.
After adjusting parallelism and no even strong pressure exists over
the complete print width, by means of a plate (B) you can set the
balance as follows:
1. Loosen screw (C, Figure 15) by approx. ¼ rotations.
2. In order to achieve a pressure balance, turn the excentric bolt (D,
Figure 15) as long as the printing result comes up to your full
expectation.
3. Tighten again screw (C, Figure 15).
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 pressure screws (A, Figure 15) to change the pressure of
printhead.
2. Turning the pressure screws (A, Figure 15) 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 15) exactly one rotation
from the right stop position counter clockwise results in the factory
settings.
NOTICE!
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.
