Cleaning the Print Head English CAUTION: After printing, the print head can be very hot. Be careful not to touch it and to let it cool before you clean it. Do not damage the print head by touching it with your fingers or any hard object. Turn off the printer, open the roll paper cover, and clean the thermal element of the print head with a cotton swab moistened with an alcohol solvent (ethanol or IPA). See the next illustration. Epson recommends cleaning of the thermal head periodically (generally every three months) to maintain receipt print quality. .
