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.
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 the paper may
not be fed correctly. To remove the paper dust, clean the platen roller.
Turn off the printer, open the roll paper cover, an
d clean the thermal elements of the thermal
head/platen roller with a cotton swab moistened with an alcohol solvent (ethanol or IPA).
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.
CAUTION
• 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.
