4.2Aligning the Printhead

Components used for Printhead alignment are illustrated in Figure 4-1.

Direct-Thermal Stock:

For best results when using direct-thermal label stock, turn the head adjust screws (Figure 4-1), 1/4 turn clockwise to move the Printhead 0.006" (0.15mm) 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.

Tag Stock or Stiff Media:

The Printer is adjusted at the factory using 5 mil (.005") thick label stock. If heavier tag stock is used, the Printhead may need to be adjusted forward.

Mechanical Adjustments:

The Printer’s 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, the following alignment procedure is required if the Printhead mount assembly has been removed or disassembled .
