Caution: Turn off the printer power before cleaning.

Caution: 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 cover-open.
2. Clean the thermal element (the area that looks like it is marked a thin black line) of the thermal head

with a cotton swab moistened with an alcohol solvent. (ethanol, methanol, or IPA)

3. After confirming that the alcohol solvent has been dried up completely, close the cover open.

※

Note: Never touch the thermal element with your hand.

Doing so can damage the thermal element.
