Known bugs and issues

Faded or faint labels

Solution: Clean the thermal print head with a cotton swab dampened with isopropyl alcohol. Wait 30 seconds before printing. Use only genuine or compatible label rolls with the correct thermal sensitivity rating.

Labels skipping or misfeeding

Solution: Calibrate the media sensor:

1. Press and hold the feed button until the light flashes
2. Load a roll of labels with the gap sensing mark
3. Press feed once — the printer will auto-calibrate
4. Test by pressing feed again — one label should advance

Bluetooth disconnections

Solution: Remove the printer from the Bluetooth device list on your phone/tablet. Turn off Bluetooth, wait 30 seconds, then re-pair. Ensure the printer's firmware is updated to the latest version.
