Common problems and troubleshooting

What should I do if the device crashes?

Press and hold the power button for 11 seconds. The device will shut down and turn off. Wait 1 minute and press the power button again to restart the device.

What should I do if the printer stops working?

Ensure that the paper tray cover is completely closed.

Check for paper jams and remove any jammed paper if necessary.

Check the USB-C cable connection—if it is not connected properly, the printer will not be able to communicate with the cash register. The indicator light on the printer will glow green when the connection is established.

What should I do if the printer does not print anything on the paper?

Ensure that the paper roll is correctly inserted in the paper tray.

Check that the correct thermal paper roll is being used.

What should I do if the printout is blurry?

Check whether the print head is dirty. If there is dirt on the print head, clean it carefully with a cotton swab and rubbing alcohol.

Only use thermal paper with high print quality to avoid streaks and blurred print images caused by low-quality paper.
