After printing, the thermal head (I1) can be very hot. Be careful not to

Do not damage the thermal head by touching it with your fingers or

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.
