Cleaning the Printer Case

Be sure to turn off the printer, and wipe the dirt off the printer case with a dry
cloth or a damp cloth.
CAUTION:
Never clean the product with alcohol, benzine, thinner, or other such solvents.
Doing so may damage or break the parts made of plastic and rubber.

Cleaning the Thermal Head

CAUTION:
After printing, the thermal head 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).
Epson recommends cleaning the thermal head periodically (generally every
3 months) to maintain receipt print quality.
