X7 Calibration error at startup.

ISSUE: 
When starting the X7 the unit will run a self-calibration test.
At start up if there is an error during this start up calibration you will get a red light, an error report and you will not be able to scan anything.

SOLUTION: 

One solution to this error is to simply clean the protective lens cover for the internal mirrors.
You can find this below:


If this lens is dirty the unit will not be able to self-calibrate correctly and it can also create issues with your scan data if it does calibrate but still has particles on it.

RECOMMENDATION: 

To clean the lens be sure to use a Microfiber type cloth only.

Be sure not to use any cloth that might scratch the lens when you clean it including paper towels.

Do not use any cleaning solutions or other liquids to clean the lens. You can use a compressed air can that are commonly used with electronics.
