Solutions

Diagnóstico rápido

Error P-02 occurs when the host computer fails to recognize the device despite it being powered on. If Windows Device Manager shows the printer with a yellow triangle or as an 'unknown device', the data link is compromised.

Solución paso a paso

  1. Replace the USB cable with a high-quality shielded one, ideally under 2 meters long.
  2. Connect to a rear USB port on your computer if using a desktop tower.
  3. Uninstall the current driver via the Control Panel and restart the machine.
  4. Download and install the latest driver from the official Pantum website.

Prevención y mantenimiento

Avoid using unpowered USB hubs, as they often fail to provide stable signal strength for laser printers. Keep data cables away from high-voltage power lines to minimize electromagnetic interference.

Cuándo llamar a un técnico

If testing with new cables and different PCs fails to restore connectivity, the printer's internal USB port on the mainboard may be damaged. In this case, hardware repair is necessary.
