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.

Cleaning the Thermal Head

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.

Cleaning the Paper Holder

section.
