1. Reinstall the Driver

Download the appropriate driver from the following links:

For Windows users, please uninstall the existing driver before reinstalling it.

2. Check the Printer Connection Status

Check Device Manager:

Press Win + R, then enter devmgmt.msc.

If the printer's name or "Printer support" is not displayed under "Universal Serial Bus controllers," it indicates a connectivity issue between the printer and the computer.

If "Printer support" or the printer model is not shown in Device Manager, it indicates an abnormal connection between the printer and the computer. Please follow the steps below to troubleshoot.

3. Check Data Cable and Connection Ports

1.Ensure you are using the original data cable. If using a non-original cable, confirm that it supports data transmission.

2.Try using a different data cable or connecting to another port on the computer.

3.If you are using a USB adapter or USB hub, please try removing the adapter and hub first, then connect the printer directly to the computer and try again.

4.Try connecting the printer’s USB data cable to a different USB port on your computer (most computers have multiple USB ports).

5.Ensure that the USB connection between the printer and the computer is correct, and that both ends of the USB cable are fully inserted into the printer and the computer.

4.Attempt to connect the printer to another computer to verify if it operates normally.
