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 rec-
ommended to be carried out once six month or one million lines.

cient care not to scratch it when cleaning it.
