3.2 Aligning the Printhead
Components used for Printhead alignment are illustrated in
Figure 3-1.
3.2.1 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.
3.2.2 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.
3.2.3 Mechanical Adjustments
The Printhead is precisely positioned on mount plate locating
pins that are adjusted at the factory. Once adjusted, the locating
pins will ensure correct alignment of all future replacement
heads. It should not be necessary to realign each new Printhead;
however, an alignment procedure is required if the Printhead
Mount Assembly has been removed or disassembled.
