Common causes

  • 1Faulty Ethernet cable or oxidized RJ45 jack.
  • 2IP address conflict within the local network.
  • 3Switch port negotiation mismatch.
  • 4Outdated firmware failing to handle network handshakes correctly.

Solutions

Diagnóstico rápido

The E-1002 error is displayed when print jobs cannot reach the printer or the web interface is inaccessible. If the Ethernet status lights aren't active, suspect a faulty cable; if they are active, the issue lies in IP assignment.

Solución paso a paso

  1. Physical check: Replace the Ethernet cable with a known-good Cat 5e or better.
  2. Port Reset: Reset the LAN port settings in the control panel to clear the TCP/IP stack.
  3. Static IP: Set a static IP address instead of DHCP to ensure connectivity stability in complex local networks.
  4. Ping Test: Verify connectivity from a PC to the printer's IP via a command prompt ping test.

Prevención y mantenimiento

Keep Ethernet cabling away from high-interference sources like motors or fluorescent ballasts. Maintaining the printer's firmware is critical, as updates provide compatibility with newer network protocols (SMBv3) that prevent E-1002 occurrences.

Cuándo llamar a un técnico

If the error E-1002 persists despite cable changes and correct IP settings, the printer's integrated Network Interface Card (NIC) may be physically compromised and requires replacement.

Steps to follow

  1. 1

    Physical Check

    Verify the Ethernet cable is securely connected to both the printer and the network switch.

  2. 2

    Network Reset

    Access the network menu, disable the LAN interface, and re-enable it to force IP renegotiation.

  3. 3

    IP Verification

    Print a configuration report to confirm the IP address is valid and free of conflicts.

Frequently asked questions

This error occurs when the printer loses communication with the print server or router due to physical layer issues or TCP/IP protocol conflicts.

Yes, E-1002 only affects network connectivity. Local USB printing should work normally.

This unit uses TNP-48 supplies. Toner does not impact network errors, but ensure genuine chips are present.

Review firmware quarterly to avoid security protocol conflicts in modern network environments.
