Solutions

Quick Diagnosis

If you can access the printer using its IP address but network services fail when using names, the issue is definitely DNS configuration.

Step-by-Step Solution

  1. Log into the printer's web interface via IP.
  2. Navigate to Network Settings -> DNS Settings.
  3. Change DNS servers to Google's public ones (8.8.8.8 and 8.8.4.4) or your ISP's.
  4. Save changes and restart the device.

Prevention and Maintenance

Always use static IP addresses for destination servers (scan to folder) instead of domain names to avoid relying on DNS resolution.

When to Call a Technician

If the error persists after setting manual DNS, the network card might have an incorrect gateway configuration.
