Printer Not Detected When Connecting
If you connected printers to the print server, but the software or web management page can not detect the printer(s), and the USB indicator light for the printer is OFF, this usually means the device has not successfully recognized that printer.
In most cases, the issue can be resolved by following the steps below.
Step 1: Check the USB Cable Connection
First, make sure the printer is powered ON.
If the printer is turned on but still cannot be detected, try replacing the USB cable between the printer and the device.
Based on feedback from many customers, simply replacing the USB cable resolves the issue in most cases.
Common causes include:
- Faulty USB cables
- Incompatible USB cables
- USB cables that are too long
A damaged or unstable USB connection may prevent the device from recognizing the printer properly.
Step 2: Check Whether the USB Port Is Working Properly
If replacing the USB cable does not solve the issue, check whether the USB port on the device is functioning correctly.
You can test this by connecting another USB device that does not require external power, such as a USB flash drive.
- If the USB indicator light turns ON, the USB port is working normally.
- If the USB indicator light still does not turn ON, the USB port or the connected device may require further inspection.
Additional Notes
When the USB indicator light is OFF, it means the device has not established communication with the printer. In most situations, the issue is related to the USB cable or printer connection rather than the printer server itself.
If you still experience issues after completing the steps above, please contact customer support for further assistance.
