Solutions

Diagnóstico rápido

Error 382 is identified when the screen freezes on this message. If the printer fails to acknowledge commands from your PC, it is highly likely that a network handshake error has occurred.

Solución paso a paso

  1. Power cycle the device by unplugging it for a full minute to clear volatile cache.
  2. Check the Ethernet cable for any signs of physical damage.
  3. Reset the IP configuration to DHCP if you have been using a static IP that might be conflicting.
  4. Cancel pending print jobs on your computer to clear the buffer memory.

Prevención y mantenimiento

Use high-quality shielded network cabling to prevent EMI interference. Regularly update the firmware via the official portal. Consistent use of genuine toner prevents sensor misreadings.

Cuándo llamar a un técnico

If the error persists after a factory reset or if the network port lights remain dark, the internal NIC might be faulty and require a service intervention.
