Chapter 4 Handling Cleaning the Thermal Head Epson recommends cleaning the thermal head periodically (generally every 3 months) to maintain receipt print quality. CAUTION After printing, the thermal head can be very hot. Do not touch it and let it cool before you clean it. Do not damage the thermal head by touching it with your fingers or any hard object. Turn off the printer, open the roll paper cover, and clean the thermal elements of the thermal head with a cotton swab moistened with an alcohol solvent (ethanol or IPA). Thermal head 4 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. Turn on the printer power only after the water has completely dried. 93
