Common causes

  • 1Roaming between access points.
  • 2Signal range limitations.
  • 3Industrial RF interference.
  • 4Low battery causing weak radio signals.

Solutions

Quick Diagnosis

If you move frequently, check your Wi-Fi signal map to identify 'dead zones' in your facility.

Step-by-step Solution

  1. Ensure you are well within the signal range of the router.
  2. Power the printer off and on to force a re-handshake.
  3. Re-verify the SSID settings via the configuration tool.
  4. Avoid crowded 2.4GHz channels if industrial equipment causes interference.

Prevention and Maintenance

Keep your firmware current. Use shielded environments if electromagnetic interference is present.

When to call a technician

If the error persists after resetting network settings and being in a known good signal area, the internal module may have failed.
