Toshiba B-453 C002 error: Sensor calibration

The Toshiba B-453 C002 error is an operational fault related to media sensor detection. This error appears when the printer cannot determine label spacing, due to incorrect sensor settings, dirt on the path, or misaligned labels. It is a recurring issue in environments with frequent material changes.

Common causes

  • 1Adhesive buildup on the gap sensor lens.
  • 2Labels misaligned relative to the moving sensor.
  • 3Threshold reading mismatch between label and backing paper.
  • 4Material with opaque backing confusing the transparency sensor.

Solutions

Diagnóstico rápido

If the printer stops and displays the C002 error, verify that the gap sensor is free of adhesive residue. If the material is transparent or high-density, the sensor may fail due to lack of contrast.

Solución paso a paso

  1. Remove the label roll and clean the sensor slot with a dry cloth.
  2. Ensure labels pass through the moving sensor slot.
  3. Enter 'Settings' and select 'Sensor Calibration'.
  4. Once material is detected, attempt a test print.

Prevención y mantenimiento

Regularly clean print heads and sensors with isopropyl alcohol. Ensure you use labels with recommended thickness to prevent light scattering in the sensor. Original ribbons guarantee sharp printing and less residue buildup.

Cuándo llamar a un técnico

If the error persists after cleaning the sensor and performing automatic calibration, the sensor module might be electrically damaged.

Steps to follow

  1. 1

    Sensor cleaning

    Clean the gap sensor with compressed air to remove label dust.

  2. 2

    Position readjustment

    Move the media sensor to align with the center of the labels.

  3. 3

    Automatic calibration

    Run the calibration from the system menu so the printer detects the new material.

Frequently asked questions

It indicates the gap sensors cannot distinguish between the paper and the gap between labels.

No, the C002 error stops printing to prevent material waste or alignment issues.

Use original Toshiba thermal ribbons and gap or black-mark labels.

Whenever you change the label roll, especially if the material generates adhesive residue.
