1. Check Scanner Connection

Check the connection points for each scanner to identify any loose connections.

Check for Cable Damage Bend the cable to see if the power turns off or the connection is lost.
Check USB Cable Connection Ensure the connector is fully inserted into the port.
Check for Non-Original Cables Non-original cables may cause interference with the port.

Check the Connection Points Move the connection points to check if the connection is intermittently lost. Shake the PD cable, handpiece, and laptop connection points to check for poor contact (Part A). Bend the connector and wire connection points to check for cable damage (Part B).
Check USB-C Port Check if the laptop’s USB-C port supports Power Delivery (PD) by visiting the laptop manufacturer’s website. Even if the laptop specifications show PD support, compatibility may vary with i600/i700 and USB-C depending on the laptop model. Try connecting to another USB-C port that supports PD. Unstable data transmission or power output from the USB-C port may cause connection issues. Poor contact in the USB-C port can also cause instability.	-
Change the Connection Method: i600, i700, i700 wireless Try connecting using a PD hub, USB 3.0 cable, and power adapter for Standard Scan.

Bend the connector and wire connection points to check for cable damage (Part B). Shake the PD hub and cable connection points to check for poor contact (Part C).
Change the Connection Method Check if the laptop supports a Power Delivery USB-C port. If it does, try connecting with a PD cable for Plug & Scan.	-

2. Try a Different USB Port

The USB port you are currently using may have unstable data transmission or power output.

Try connecting to a different USB port to test.

4. Update Chipset Drivers

Chipset drivers can be downloaded from the laptop manufacturer's support website. 

5. Update Windows

Update the Windows OS to the latest version.

6. Cross-Check Accessories

Test the connection with different accessories (PD cables, USB 3.0 cables, PD hubs).

7. Test on Another PC
