Common causes

  • 1Duplicated IP address on local network.
  • 2Degraded Ethernet cabling.
  • 3DHCP conflict.
  • 4Outdated firmware causing TCP/IP stack errors.

Solutions

Quick Diagnosis

Check the rear Ethernet port for flickering activity lights. If these are dark, the physical link is absent. If they are lit, focus on software-level settings like IP conflicts.

Step-by-Step Solution

  1. Check Physical Connection: Ensure the Ethernet cable is securely clicked into the RJ45 port.
  2. Verify Network Admin: Log into the printer's web interface to check its network status.
  3. Manual Setup: Set a static IP outside the main DHCP scope for consistent connectivity.
  4. Connectivity Test: Ping the printer's IP from a computer on the same network.

Prevention and Maintenance

Use shielded cabling (CAT6) near industrial machinery to prevent packet loss. Regularly update firmware to ensure the latest network protocol compatibility.

When to call a technician

If static IP settings and cable replacement do not solve error e-404, the unit's internal network controller might be failing.

Frequently asked questions

Error e-404 indicates the printer cannot reach the network server or there is an IP address conflict.

Yes, assigning a static IP address in the network settings is the best way to prevent this error from recurring.

Use a Category 6 (CAT6) cable to ensure stable data transmission.

Update your firmware regularly and place the unit away from strong electromagnetic interference sources.
