Solución paso a paso

  1. Power off the printer immediately.
  2. Open the printer cover and remove the receipt roll.
  3. Clean the print head carefully using an approved thermal cleaning pen or isopropyl alcohol wipes.
  4. Close the unit and perform a test print.

Prevención y mantenimiento

Clean the thermal head every time you replace the paper roll. Using high-quality receipt paper reduces the amount of residue deposited, extending the life of your print head significantly.
