Adjusting the Printhead Position
In order to achieve the best possible print image the following printhead settings are necessary:
•
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.
!
Attention!
Risk of damage.
Attempting to adjust the printhead when the fixing screws (1) are tight can lead to defects at the printhead
assembly.
Always loosen the fixing screws (1) before adjusting the printhead.
