8. Periodical Cleaning
Printed characters may become partially unclear due to accumulated paper dust and dirt. To
prevent such a problem, paper dust collected in the paper holder and paper transport section and
on the surface of the thermal head must be removed periodically. Such cleaning is recommended
to be carried out once six month or one million lines.
8-1. Cleaning the Thermal Head
To remove blackish dust collected on the surface of the thermal head, wipe it with Isopropyl
alcohol (IPA).
Note: The thermal head is easy to damage, so clean it gently with a soft cloth. Take sufficient
care not to scratch it when cleaning it.
8-2. Cleaning the Paper Holder
Use a soft cloth to remove paper dust from the paper holder and paper transport section.
