  • 2IP address conflicts within the office local area network.
  • 3Outdated firmware failing to handle network protocols.
  • 4Hardware failure of the internal network interface card.

Solutions

Diagnóstico rápido

You can identify this error when the control panel displays a connection alert while you are attempting to print. If the rear Ethernet lights are completely dark even when connected to an active port, the printer is not detecting a valid network carrier signal.

Solución paso a paso

  1. Check network cable: Inspect the Ethernet cable for damage and ensure it is securely seated in both the printer port and the network switch.
  2. Power cycle: Turn off the printer, unplug it from the wall, and wait 60 seconds before powering it back on to flush the internal network stack.
  3. Review network settings: Access the network menu on the control panel to confirm IP settings are correct and not conflicting with other devices.

Prevención y mantenimiento

Ensure your workspace is free of excess dust that could degrade contact points in the Ethernet port. We recommend standardizing your network cables to CAT6 specifications. Keeping your firmware up to date helps the device negotiate effectively with modern router security settings.

Cuándo llamar a un técnico

If you have verified the connection with a different wall jack and a different cable, yet the 650 error persists, the network interface card on the mainboard may have failed.

Frequently asked questions

The 650 error signifies a network interface issue. It usually occurs when the printer cannot establish a handshake with the local network router.

It is not a fatal hardware error but a communications one. Most users resolve it by simply power cycling their networking equipment.

No, toner cartridges are unrelated to networking errors. Changing the toner will not clear this specific code.

Using high-quality shielded Ethernet cables and assigning a static IP address to your printer can significantly improve network stability.
