Common causes

  • 1Data handshake protocol interrupted by external interference.
  • 2Driver incompatibility with current host firmware version.
  • 3Connection timeout due to prolonged inactivity.
  • 4Temporary corruption of the input buffer memory.

Solutions

Diagnóstico rápido

The error 401 usually surfaces after a lapse in data transmission or when attempting to resume operations after inactivity. Check for intermittent LED status indicators on the wireless module.

Solución paso a paso

  1. Power cycle the device by holding the power button.
  2. Unpair the printer in your computer or terminal's settings menu.
  3. Set the PB52 to discoverable mode.
  4. Run a new search from the host terminal and re-establish the connection.

Prevención y mantenimiento

Update the communication firmware using official configuration tools. Avoid operating in areas with high 2.4GHz radio frequency congestion. Maintain current drivers on the host device to prevent protocol mismatches.

Cuándo llamar a un técnico

If the issue persists despite numerous re-pairing attempts and trying different host devices, the internal wireless module may have sustained physical damage.
