Cleaning the Case
Use a dry cloth or lightly dampened cloth to clean the case. Disconnect the power cord from the
wall outlet before doing this.
Avoid using alcohol, benzene, thinner, trichloroethylene, or ketone-based substances to remove
dirt or foreign matter from the printer, because these substances can affect or damage plastic and
rubber parts.
Cleaning the Thermal Head
CAUTION:
❏
Turn off the printer power before cleaning.
❏
Note that the thermal head (thermal element and radiation plate) becomes very
hot during normal operation, creating the danger of burn injury. Be sure to wait for
about 10 minutes after turning printer power off before beginning the cleaning.
1. Open the paper roll cover.
2. Clean the thermal element (the area that looks like it is marked with a thin black line) of the
thermal head with a cotton swab moistened with an alcohol solvent (ethanol, methanol, or
IPA).
CAUTION:
Never touch the thermal element with your hands. Doing so can damage the
thermal elements.
3. After confirming that the alcohol solvent has dried completely, close the paper roll cover.
