motors are very hot and could cause burns.
Precautions in handling the fine coating of the case
(only for Fine Coating Case model)
A fine coating is used for the external surface of the plastic case of the printer, which makes
wiping and removing kitchen stains easy; however, you should note the following when
cleaning the surface in order to preserve the quality of the coating (the metal plate and the inside
of the case do not have the fine coating):
❏ Do not scrub the surface with a hard object. Otherwise, the case will be scratched and harder
to clean.
❏ Do not use a cleanser that includes polishing materials such as grains of glass, metal, or
ceramics. Otherwise, the case will be scratched and harder to clean.
❏ Never use disinfectant, bleach, alcohol, benzine, thinner, chlorine solvent, or ketone solvent.
Otherwise, the case will be harder to clean, and the case may be seriously harmed or even
deformed and its color may be changed.
❏ The label may come off of the fine coating of the case if harsh cleaning methods are used
.
