Common causes

  • 1IP conflict with another device on the network.
  • 2Degraded or low-category Ethernet cable.
  • 3Incorrect Gateway configuration in the network menu.
  • 4Electromagnetic interference from poorly shielded cabling.

Solutions

Diagnóstico rápido

If the printer stops receiving tasks, check the Ethernet port LEDs. If there is no activity, the network is not recognizing the printer.

Solución paso a paso

  1. Physically inspect the Ethernet (RJ45) cable.
  2. Access the 'Settings' menu and ensure 'Network' is set to 'Wired' or 'Wireless'.
  3. Reset the network interface.
  4. Attempt a ping test from a computer to the printer's IP.

Prevención y mantenimiento

Assign a static IP to avoid network conflicts. Keep cables away from heavy machinery to avoid electromagnetic interference.

Cuándo llamar a un técnico

If IP settings are correct but the network card fails to respond to constant pings, the interface card may be faulty.

Frequently asked questions

This error happens when the printer loses communication with the host server or network gateway, preventing print data flow.

If you need real-time label printing, it is urgent, as it blocks the printer from receiving remote print orders.

Check that the gateway, subnet mask, and assigned IP are compatible with your corporate network segment.

Yes, periodic updates often contain connectivity patches for complex industrial environments.
