Cleaning
Wipe off any foreign matter such as media dust, dirt and adhesive substances
built up around the prinhead 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 printhead after printing on thermal
media for long periods, which will guarantee the print quality and extend the
life of the printhead.
Note: Always use the head cleaner when cleaning the printhead.
