Toshiba B-SA4TM error ERR-02: Fix

The Toshiba B-SA4TM error ERR-02 is a notification that the media sensor (label sensor) is unable to identify the start or stop point of each label. This flaw prevents correct synchronization during printing, leading to feed errors or abrupt machine stops while attempting to print labels.

Common causes

  • 1Dust or debris obstructing the label sensor slot.
  • 2Misalignment of labels relative to the sensor.
  • 3Media sensor de-calibration after material switch.
  • 4Failure of the optical detection sensor.

Solutions

Diagnóstico rápido

ERR-02 appears if the sensor cannot 'see' the labels. Inspect the paper path to ensure the sensor slot is free from dust, debris, or label remnants.

Solución paso a paso

  1. Sensor Cleaning: Use a soft brush or compressed air to clean the label sensor slot.
  2. Load media: Ensure the roll is aligned correctly so the sensor tracks the gap between labels.
  3. Manual Calibration: Run the autocalibration command from the control panel.
  4. Retry: Press the 'feed' button to see if the machine stops correctly at the label edge.

Prevención y mantenimiento

Calibrate the sensor whenever changing label sizes or materials. Keep the internal area dust-free with regular monthly cleaning.

Cuándo llamar a un técnico

If the error persists after cleaning and calibration, the sensor is likely misaligned or the electronic detection element has permanently failed.
