Note:

Depending on the roll paper used, paper dust may stick to the platen roller and roll paper end sensor. To remove the paper dust, clean the platen roller and roll paper end sensor with a cotton swab moistened with water.

EPSON recommends cleaning of the thermal head periodically (generally every three months) to maintain receipt print quality.

Keep pieces of metal away from contact with the head thermal elements and driver IC as they are extremely susceptible to damage.

If thermal paper contains Na, K, CI or other ions, be sure to use the specified paper as ions may adversely affect the head thermal elements.
