What should I do if the printer won't turn on and the indicator doesn't light up?
For safety reasons, the printer is shipped from the factory with a low battery charge and may need to be recharged before initial use. If you recharge the printer but it still doesn't turn on after pressing and hold the power button for 2 seconds, please contact customer service to help you determine whether the printer's power button is working properly.
Why does the printer turn off automatically?
1.If bluetooth is disconnected for more than 5 minutes, the device automatically shuts down if no operation is performed.
2.Bluetooth automatically shuts down if no operation is performed after 90 minutes.
What could cause a firmware update to fail?
Please refer to the following troubleshooting steps:
1. Make sure the printer has enough battery. To prevent an update failure caused by power loss, firmware updates cannot be performed if the printer has low battery.
2. Make sure no other Bluetooth devices are interfering with the printer. Nearby Bluetooth devices may interfere with the printer's Bluetooth signal and prevent a firmware update.
If none of these troubleshooting steps work, please return to the previous page, tap Report Error, and include the error log so technical support can resolve your issue.
