6.3 Adjusting the Printhead Position (Corner Type)
Complete the following printhead settings to achieve the best possible
print image:
Align the heating line with the highest point of the print roller.
Density of the print image is the greatest at this point.
Set the parallelism of horizontal lines with the edge of the label.
CAUTION!
The printhead assembly can be damaged.
Attempting to adjust the printhead when the fixing screw (J
and HI) is tight can lead to defects at the printhead assembly.
Always loosen the fixing screw (J or H) before adjusting
the printhead.
NOTICE!
Open and close the printhead locking device after each step of
the adjustment.

An important characteristic for a high quality print is the parallelism of
the focal line of the thermal printhead to the pressure roll. Because of
the fact that the position of focal line of the printhead depends on
fluctuations caused by production, it is necessary to adjust the
parallelism.
