5. Maintenance

5.1 Changing Label Rolls

When a label roll is depleted or you need to switch label types, follow the label loading instructions in Section 3.3. Ensure the printer is powered on when changing labels, as it will automatically detect and calibrate the new roll.

Over time, dust or adhesive residue may accumulate on the print head, affecting print quality. To clean the print head:

  1. Power Off: Turn off the printer and disconnect the power adapter.
  2. Open Cover: Open the top cover of the printer.
  3. Clean Print Head: Gently wipe the thermal print head (the dark strip located inside the printer where labels pass) with a lint-free cloth lightly dampened with isopropyl alcohol. Allow it to dry completely before closing the cover and reconnecting power.

Caution: Do not touch the print head with bare hands, as oils can damage it. Do not use abrasive materials or harsh chemicals.
