How to Check The Fingerprint Sensor When It’s Not Working

This is a detailed guide for what you should do first when you have to press the fingerprint sensor many times to clock in or in cases you feel the sensor is not working.

--------------------------------------------------------------------------------------------------------------------------------------

Step 1. Confirm your device is based on Linux or ST platform.

Linux: VF30 Pro, W1 Pro, W2 Pro, EP300 Pro, C2 Pro, OA1000 Pro, A350, M5 Plus
ST: T5 Pro, M5 Pro, VF30, VP30, P7, M7, T5, M5, D200, OC500, OC580, TC580, TC500

Contact your supplier if your device isn’t listed.

Step 2. Get fingerprint pictures.

• If your device is based on the Linux platform,

       1. Input “000031” and “OK”, and the screen will show as the picture below. 
       2. Put a finger on the sensor. Fingerprints will show on the screen.
(C2 slim and M-Bio are the models based on the Linux platform without the screen, so this step is not available for them.)

• If your device is based on the ST platform,

       1. Download the image tool.
       2. Connect the device to the PC with a network cable and run the tool.
       3. Click “Get Image” to see fingerprints when you put your finger on the sensor.


Step 3. Assess the pictures.

If it’s clear, the fingerprint sensor shouldn’t be a problem.
If it’s broken, please send the pictures to our support team and we’ll assist you with the problem.
