7. How to obtain a high quality model?
Use USB 3.0 or above port;
Hi-Quality mode should be chosen;
Move your hand or rotate the turntable slowly during scanning;
Keep perfect distance according to the prompt during scanning;
Adjust the exposure yourself to avoid red or blue part appearing in IR image;
Keep scanning until all the parts you want are adequately scanned (the quality map turns green in

Set smaller resolution when optimize the point cloud.
11. FAQs
1. Can the scanner be powered directly by a mobile phone, without using a charging handle?
If the mobile phone supports USB3.0 Type-C port, then it can power the scanner directly. However, this
consumes a lot of power and we recommend using the charging handle for a stable power supply.
2. How to avoid tracking loss?
Return the scanner to the previous correct position and hold on for 2s to retrieve the image.
3. What is the scanning frame rate of the scanner?
The scanner provides depth images of 30fps, supports a scanning frequency of 30 fps theoretically.
However, the actual scanning rate depends on the calculation power of the mobile phone or PC
involved in the process. In practice, the scanning frame rate can be lower than 30 fps. We recommend
using a device with high calculation power to achieve optimal results.
4. What system configuration is recommended for the scanner?
For mobile phones, it is recommended to use smart phones with USB3.0 interface and running memory
of more than 8G, such as Samsung S22, S23, etc. For computers, it is recommended to use i5 or above
with USB3.0 interface.
5. Does CR-Scan support USB2.0?
The scanner supports USB2.0, and the scanning frame rate will be limited by the lower data transmission rate.
In order to adapt to USB2.0, the scanning accuracy will also be reduced and some functions may be forbiden.
6. How long can the charging handle support continuous scanning?
It can support more than two hours of continuous scanning by directly using the charging handle. Generally
speaking, the scanning time of small and medium-sized objects is within 5min, that is, the charging handle
can support 20 to 30 small and medium-sized objects.
7. How to restore the connection when the mobile phone scanner is disconnected?
Plug the USB cable on the handle of the rechargeable battery again.
8. Some Android phones show disconnection when they are disconnected from the scanner for a
certain period of time. How to restore the connection?
If the device is disconnected for more than a certain time (for example, 10 minutes), some Android systems
will automatically turn off the OTG connection, and the device status is always offline. The device can be
connected only after the OTG switch is turned on in the Android system.
