Solutions

Quick Diagnosis

The error is visible when the printer display stops updating and print jobs stay in the queue. Confirm if the issue is network-related by checking if the Wi-Fi icon is blinking red, indicating a lost connection.

Step-by-Step Solution

  1. Power cycle the printer and the router to refresh DHCP lease data.
  2. Verify Wi-Fi status using the network configuration menu on the front panel.
  3. Set a static IP address through the integrated web server to prevent conflict.
  4. Reinstall print drivers if the machine is still not discovered by host computers.

Prevention and Maintenance

Keep the printer firmware updated. Ensure the device is positioned away from large metal objects that might shield Wi-Fi signals. Using genuine toner is recommended to prevent sensor obstruction.

When to Call a Technician

If the machine fails to obtain an IP address despite multiple network resets, contact technical support for potential network card failure.
