To prevent such a problem, paper dust collected in the paper holder and paper transport section and on the surface of the thermal head must be removed periodically. Such cleaning is recommended to be carried out once six month or one million lines. To remove blackish dust collected on the surface of the thermal head, wipe it with Isopropyl alcohol (IPA). The thermal head is easy to damage, so clean it gently with a soft cloth. Take sufficient care not to scratch it when cleaning it. Use a soft cloth to remove paper dust from the paper holder and paper transport section. The paper should not be touched during printing. Shift the paper during paper ejection may cause a feed failure or paper jam. a. Cleaning the Thermal Head of the Receipt Printer Note: b. Cleaning the Receipt Printer's Paper Holder
