Solutions

Diagnóstico rápido

If the printer is unreachable, first verify the Ethernet status lights. If the network is healthy, the issue is likely a driver conflict or an incorrect IP configuration. Testing via USB is a great way to isolate whether the problem lies with the network card or the host computer settings.

Solución paso a paso

  1. Inspect hardware: Confirm all cables (Ethernet/USB) are tightly connected and free of damage.
  2. Network reset: Use the printer's menu to reset the network settings to factory defaults.
  3. Driver check: Reinstall the official Toshiba B-EX4T1 driver, ensuring the communication port matches the current IP address.
  4. Ping test: Run a ping command from your computer to verify connectivity to the printer's IP.

Prevención y mantenimiento

Use shielded, high-quality network cables to minimize interference. Assign a static IP address to the printer within your network environment to prevent conflicts. Regularly update the printer's firmware to ensure stability with newer network security protocols.

Cuándo llamar a un técnico

If replacing cables, resetting parameters, and checking drivers does not resolve the issue, the printer's internal network card (NIC) might be faulty, requiring professional repair.
