Purpose of This Manual
This manual provides information to operators of the TM-U230 to describe
basic operations to enable safe and correct use of the printer.
Notes for Cleaning the Printer
The following instructions apply only to printers with the fine coating.
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.
❏Do not 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.
