Maintenance

1. Turn the printer off, disconnect the power cord, and open the cover.
2. Wait for the printer head to cool down, as it may be very hot after printing.
3. Clean the printer head thoroughly using an alcohol swab (do not use water).
4. Wait until the alcohol has completely vaporized before closing the cover.
5. Reconnect the power cord and print a test page to verify cleanliness.

NOTICE

• Ensure the printer is powered off when performing maintenance.
• Do not touch or scratch the printer head surface, rollers, or sensors.

PRO TIPS

• Whenever you change the label type, run the automatic label identification feature.
• Press the printer button to get a check page, which can be used to skip a blank label.
• To run a self-test, press and hold the feeder button until you hear two short beeps.
• Avoid using poor quality labels, as they can damage the printer.
• Regularly clean the printer head.
• If paper becomes jammed: turn off the printer, allow the print head to cool down, open the cover, and check the rubber roller. If dirty, clean it with alcohol and allow it to dry completely before turning the printer back on.
• Always insert the printer into the same USB port on your computer to prevent the creation of duplicate printer entries in your operating system.
