• During cleaning, do not apply excessive force to the thermal head or
bang the head surface with a hard object.
• Do not use sandpaper or the like because doing so may result in dam-
age to the heating elements.
• After cleaning, wait until the ethyl alcohol is completely evaporated,
and then close the cover and perform an operation check.
• Do not use thinner, benzene, or the like because doing so may cause
discoloration and deformation of the instrument.
• Prolonged use may result in paper dust and other white particles
adhering to the surface of the roller. Small amounts of particles will not
affect the printer but if you are worried you can use a commercially
available blower brush for cameras or similar device to remove them.
