• To change the thermal head, please refer to the printer’s operation manual.
• Use caution not to damage or contaminate the new thermal head during replacement.
• Do not touch the heating element of the thermal head during replacement. Chlorine in the finger’s sweat may damage the protective layer of the thermal head. If you touched the heating element, clean it immediately.
• After the thermal head has been replaced, gently wipe the heating element with a soft cloth soaked with a cleaning agent or alcohol.

If there is no spare thermal head but printing must be continued even if the print quality is low, the head error can be ignored by switching the DIP switch No. 5 to OFF on the screen.

(This will result in a white stripe in printing where the wiring is broken.)
