Solutions

Diagnóstico rápido

The 602 error is purely communication-related. If the rear port lights aren't blinking, swap the Ethernet cable to rule out a damaged cord. If they are, it's an IP configuration issue.

Solución paso a paso

  1. Check Cables: Replace the Ethernet cable with a Cat5e or Cat6 cord.
  2. Reboot Network: Cycle your router power to clear ARP tables.
  3. Set Static IP: In 'Admin' -> 'Network' settings, set a static IP to stabilize connection.
  4. Connectivity Test: Perform a 'ping' test from your PC to the printer's IP.

Prevención y mantenimiento

Avoid excessively long Ethernet runs or unshielded cables. Assigning a permanent static IP address is the single best prevention strategy.

Cuándo llamar a un técnico

If cables, IP settings, and router resets do not resolve the issue, the printer's physical NIC (Network Interface Card) may be faulty.

Frequently asked questions

Error 602 means the device cannot talk to the network. This is usually due to poor cabling, IP conflicts, or router settings.

Usually not. It is typically a setup, cabling, or network configuration error.

For office use, a static IP prevents error 602, which often occurs if the router changes the printer's dynamic address.

Check annually to ensure compatibility with modern networking protocols.
