每当我给链轮充电时，指示灯都会闪烁绿色和红色，它不会打印。我已经尝试了所有解决方案，包括升级固件，重新安装应用程序和重置设备。我上次使用链轮并正常工作是在大约 2 个月前，我从未进行过任何修改或使用过任何不受支持的打印纸。谢谢

Turn off your mobile device, and then turn it back on.
Turn on the Sprocket.
Remove the Paper Cover, and then use a narrow object, such as a pen or paperclip, to press and hold the Reset button for 3 seconds until the Sprocket turns off.
NOTE:
The location of the Reset button varies by Sprocket model. Typically, the button is located underneath the Paper Cover, but can also be found on the outside next to the charging port.
