Solutions

Diagnóstico rápido

The SC669 error triggers during startup. If you can copy but cannot print, the error is isolated to the network card initialization.

Solución paso a paso

  1. Disconnect Network: Remove the Ethernet cable from the rear port.
  2. Power Cycle: Turn the machine off and on without the cable attached.
  3. Reconnect: If it boots correctly, reconnect the cable. If the error returns, the NIC hardware is faulty.

Prevención y mantenimiento

Ensure high-quality shielded Ethernet cables are used to prevent signal noise. Use surge protection for network devices.
