5-2-1 Cleaning Head
Paper dust on the heating elements may lower the print quality. In this case, clean the print head as follows:
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. Bu 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.
