Step 1: Power Off and Restart
First, press and hold the power button for about 8 seconds until the "Powering Off" message disappears from the screen, completely blacking out the device. Next, press and hold the power button again for about 5 seconds until the "Youdao" logo appears, and wait for the homepage to display. Finally, repeat the restart steps once. This usually resolves the issue of the scanner light not being on.
Step 2: Power On Operation
To resolve the scanner light not being on, the first step is to power off the device. Press and hold the power button for about 8 seconds until the "Powering Off" message disappears from the screen, ensuring the device is completely off. Next, press and hold the power button again for about 5 seconds until the "Youdao" logo appears, and wait for the homepage to display. Finally, to ensure the problem is completely resolved, repeat the restart steps once more. This series of power off and restart operations usually effectively resolves the issue of the scanner light not being on.
If the problem persists after powering off and restarting, you can try powering on the device. First, go to the device's homepage and then select the "More Settings" option. Next, locate and click on the "About" section, then select "Reset Options." Finally, click "Reset System Settings" to restore the device to its factory default settings. This series of steps can sometimes resolve potential issues such as the scanner light not lighting up.
If the scanner light lights up normally after trying the above steps, the problem is likely with the system, possibly due to a random failure to load the camera.
