"Scanner is not connected" error troubleshooting for the Artec Micro


The Artec Micro scanner is either not detected properly in Artec Studio, or keeps losing connection:







1) Power on the Micro scanner, and check if the Artec3D logo is projected onto the calibration board during the initialization/boot procedure of the scanner (within around 5 seconds of power-on).
If the logo does not appear, the scanner is likely to have hardware issues. Please contact


2) Check the USB connection and USB port
Avoid connecting the scanner to any kind of USB hub or port multiplier.
Preferably, connect the scanner to a USB port located directly on the PC motherboard.

Attempt the following start-up procedure:
- Turn off the scanner and shut down the computer.
- Connect the scanner to a USB port located directly on the PC motherboard.
- Power on the scanner.
- Power on the PC and wait until it is fully booted.
- Run Artec Studio and check whether the issue has been resolved.

(!) The Artec Micro scanner requires a USB 3.0 port. It will not work if connected to a USB 2.0 hub or port.
Generally, the scanner is also compatible with USB 3.1, 3.2, and newer USB ports. In some cases, a USB C to USB A adapter might be required.

In very rare cases, the USB chipset on the computer motherboard may be incompatible with the Micro scanner. On desktop computers: i
nstalling a USB 3.0 PCIe card and connecting the scanner directly to the PCIe card will resolve the issue.


3) Check the device status in Windows Device Manager (and update or reinstall drivers).

If the scanner is connected and recognized properly, you will be able to find the following items in Windows Device Manager:

- uEye UI-388x Series

- uEye UI-388x Series

- USB Serial Port (COMx)
