Cleaning the Print Head
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 paper roll cover, and clean the
thermal element of the print head with a cotton swab moistened
with an alcohol solvent (ethanol, methanol, or IPA).
EPSON recommends cleaning of the thermal head periodically
(generally every three months) to maintain receipt print quality.
