8. How do I clean the print head properly?
(1) Use ethanol and cotton swabs.
(2) Turn off the printer and let it cool for a few seconds.
(3) Take the paper roll out and put it aside.
(4) Use a clean small cotton swab (the print head space is
narrow) to dip a little ethanol to wipe the dirt on the surface of
the print head gently (do not scrape the print head with hard
objects, otherwise the thermal-sensitive tablet will be
permanently damaged and become irreparable).
(5) After cleaning, double-click the power button to do a
self-test when the surface is completely dry.
