CAUTION: After printing, the thermal head and the frame on its side (indicated in the circle in illustration below) can be very hot. Be careful not to touch it and to let it cool before you clean it. Do not damage the thermal head by touching it with your fingers or any hard object. 

3. Clean ONLY the thermal elements of the thermal head with a cotton swab moistened with an alcohol solvent (such as ethanol or IPA).


Setting the DIP switches

CAUTION: Be sure to turn off and unplug the printer before removing the cover of the DIP switches. Removing it while the printer is turned on may cause problems such as an electric short, which leads to a malfunction of the printer.

1. Turn off the printer, and unplug it.


2. Turn over the printer so that the bottom of the printer is facing up.

3. Remove the DIP switch cover by removing the screw.


4. Set the DIP switches using a fine-tipped tool.

  • Bank 1 should all be off.
  • Bank 2 numbers 1, 4, and 8 should all be on.

5. Replace the DIP switch cover, and fix it in place by installing the screw.


6. Power on the printer. The new settings becomes effective after the printer is turned on.
