Solutions

Diagnóstico rápido

The error occurs when the 'P-touch Editor' shows the status as 'Offline'. Confirm if the network indicator light is solid or blinking red, and ensure the printer is visible within your network's list of active devices.

Solución paso a paso

  1. Check physical links: Swap the USB cable or try a different port to rule out hardware failure.
  2. Network verification: Print a network configuration page by holding the power button until the lights flash.
  3. Driver update: Download and install the latest drivers from the Brother support site for your OS.
  4. Reset Spooler: In Windows, stop and restart the 'Print Spooler' service in the Control Panel.

Prevención y mantenimiento

Assign a static IP address to the printer via your router settings to prevent connection drops caused by DHCP changes. Keep your printer's firmware updated to avoid compatibility issues with modern OS updates.

Cuándo llamar a un técnico

If you have reinstalled the drivers and performed a full network reset but the printer remains invisible to all networked computers, the internal network interface card (NIC) may be malfunctioning.
