1. Check if there is anything blocking the TOF sensor of the machine. The TOF position should not be blocked.

2. When the TOF sensor is dirty, use a soft tissue, glasses cloth, etc. to wipe the TOF sensor lens. The location of the TOF sensor is shown in the figure below as ‘4’.

We apologize for any inconvenience this may cause.
