Thermal head
Note : The thermal head is susceptible to damage. When cleaning it, use a soft
cloth and be especially careful not to damage the head.
Note : Immediately after printing, the thermal head is hot. Before cleaning the
head, allow the head enough time to cool.
Note : Because the thermal head is susceptible to damage by static electricity,
take precautions to prevent the generation of static electricity.
Note : Do not turn on the printer until all alcohol has dried.
Note : Do not use a solvent other than ethyl or isopropyl alcohol.
