automatically when the temperature returns to normal.
❏ Make sure that the roll paper cover is properly closed.

❏ When the printer power is on, if the Error LED is on and the Battery LED is
off, the remaining battery charge is not enough for printer operation. Replace
or charge the battery.
❏ When the battery is being charged, if the Error LED is on, an abnormality has
occurred. The battery must be replaced with a new one.
❏ Turn off the power, wait several seconds, and then turn it on again. If the
error remains, contact a qualified service person.
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.
Do not use water. Use an alcohol-based solvent only.
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 print quality.
