Cleaning the Thermal Head

CAUTION:
After printing, the thermal head and the frame on its side (indicated in the
circle in Illustration N) can be very hot. Be careful not to touch it and to 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). See Illustration R.
Epson recommends cleaning the thermal head periodically (generally every
3 months) to maintain receipt print quality.
