Adjustments and Maintenance

6.
Rotate each Burn Line Adjustment Screw clockwise about one-quarter of a turn then print another
VALIDATION LABEL and examine its print quality. Repeat this step until an image with even contrast
begins to be produced across the label.
7.
Continue dialing in the print quality, queuing more labels as necessary. Rotate the Burn Line
Adjustment Screws clockwise about one-eight of a turn, carefully as needed (see note below),
reducing your adjustments as print quality is achieved. (Aside from being visually acceptable, correct
alignment can be determined by scanning the printed bar codes for compliance where, with correct
heat and speed settings, the quality of the ladder bar codes becomes a critical indicator.)
Note:
When the Locking Screws are snug, turning the Adjustment Screws counterclockwise will
NOT move the printhead outward; if you have adjusted the printhead too far inward,
restart the procedure beginning at Step 1.
8.
Tighten both Locking Screws then print a final VALIDATION LABEL to verify the adjustment.

Printhead Voltage
CAUTION
This procedure requires voltage measurement: Use extreme caution.
The printhead voltage adjustment is required (1) when replacing the power supply, or (2) if the factory
voltage setting of the power supply has been changed. (Voltage adjustment is not typically required
during routine printhead replacements.) Adjust the printhead voltage as follows:
