Cleaning
Wipe off any foreign matter such as media dust, dirt and adhesive substances
built up around the printhead with the head cleaning pen (head cleaner)
provided, and use a soft cloth soaked in ethyl alcohol for the platen etc.
It is particularly important to clean the thermal printhead after printing on
thermal media for long periods, which will guarantee the print quality and
extend the life of the thermal printhead.
Note: Always use the head cleaner when cleaning the thermal printhead.
Caution
Do not use any solvent other than ethyl alcohol. Solvents such as
benzene, acetone and thinner will dissolve plastic parts and destroy
the thermal printhead, platen and much of the printer!
Try to avoid using "excessive amounts" of ethyl alcohol to clean the
platen. Excessive use will harden the platen surface prematurely.
