      If you're experiencing poor printing quality on tape, consider these potential solutions: * Check the position of the M roller lever. * Ensure the tape and ink ribbon are properly set. * Verify the tape width setting is correct. * Make sure there's no dirt or stains on the tape. * If the ambient temperature is below 15°C or above 35°C, try adjusting the “PRINTING DENSITY” in the OPTION menu. * Ensure the feeding roller is clean and no tape or tube waste is caught in the exit. * Adjust the “CUTTING POSITION” in the OPTION menu.

      If the half cutting function isn't working correctly, check the following: * Ensure the half cutter is properly set and the “Half cutting depth adjustment lever” is in the correct (TUBE) position. * If the cutter has been used for more than 5,000 cuttings, replace it. * Make sure you are using the exclusive half cutter LM-HC340 (yellow color). * Check for any tape or tube waste caught in the exit.
