Cleaning The Thermal Head - Epson TM-T88V-i Technical Reference Manual

Cleaning the Thermal Head

Epson recommends cleaning the thermal head periodically (generally every 3 months) to maintain
receipt print quality.
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.
CAUTION
Turn off the product, 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 Isopropyl Alcohol).
Depending on the roll paper used, paper dust may stick to the platen roller and roll paper end
sensor. To remove the paper dust, clean the platen roller and roll paper end sensor with a cotton
swab moistened with water. Turn on the product power only after the water has completely dried.
