Aligning the Printhead

Components used for Printhead alignment are illustrated in
Figure 5-1.

5.2.1 Direct-Thermal Stock

For best results when using direct-thermal label stock, turn the
head adjustment screws 1/4 turn clockwise to move the Printhead
0.006" (0.15 mm) back on the roller. When the Printhead is
aligned with thermal-transfer stock the Printhead is forward on
the roller so that the ribbon will separate from the label while the
wax ink is still liquid ensuring good print quality. With direct-
thermal stock, the Printhead burn line needs to be further back
on the roller where there is more contact with the roller. This
causes heat to transfer to the paper more efficiently.

5.2.2 Tag Stock or Stiff Media

The Printer is adjusted at the factory using 5 mil thick label
stock. If heavier tag stock is used, the Printhead may need to be
adjusted forward.
