Cleaning the Printer

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. Be sure to
unplug the AC cable while cleaning.
CAUTION

Cleaning the Thermal Head/Platen Roller

Epson recommends cleaning the thermal head periodically (generally every 3 months) to maintain receipt print
quality. Depending on the roll paper used, paper dust may stick to the platen roller and cause an irregular paper
feed. To remove the paper dust, clean the platen roller with a cotton swab moistened with water. Turn on the
printer power only after the water has completely dried.
Turn off the printer and open the roll paper cover. Clean the thermal elements of the thermal head with a cotton
swab moistened with an alcohol solvent (ethanol or IPA).
CAUTION
Thermal head
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.
• 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.
