Toshiba TEC B-EX4D2 error E-102: Sensor Fault

The Toshiba TEC B-EX4D2 error E-102 is activated when the unit's optical sensor fails to detect the registration mark (black mark) on the print media. This fault, common in high-volume environments, is usually resolved by recalibrating the media sensors. It is vital to understand why the Toshiba TEC B-EX4D2 error E-102 affects the production flow if the alignment is not precise.

Common causes

  • 1Misalignment: Sensor is not positioned over the black mark or gap.
  • 2Dirt: Accumulation of paper dust on the sensor lens.
  • 3Incorrect calibration: Threshold values do not match the current media.
  • 4Physical damage: Sensor has been impacted or has a loose cable.

Solutions

Diagnostic

The E-102 appears on the LCD screen when the sensor does not distinguish between the label and the space (or black mark). If the printer does not stop at the registration mark when pressing 'feed', the issue is calibration or a dirty sensor.

Step-by-Step Solution

  1. Adjust media: Ensure the material is centered under the sensor guide.
  2. Clean sensor: Use a swab with isopropyl alcohol to clean the registration sensor.
  3. Calibrate: Go to the menu, search for 'Sensor Calibration' and follow on-screen instructions for your media type.
  4. Test: Run a test print.

Maintenance

Perform internal cleaning with compressed air weekly to prevent paper dust from blocking sensors. Using original consumables ensures the black mark contrast is correct for the sensor.

When to call a technician

If the E-102 error appears immediately after cleaning and calibrating, the sensor may have an internal emitter or receiver fault.

Frequently asked questions

This error occurs when the printer cannot detect the registration mark (black mark) on the thermal paper.

The error halts printing to prevent label waste and overprinting, requiring manual calibration.

It is suggested to use high-quality thermal labels with a clearly defined black mark.

Regular cleaning of the platen roller and registration sensor every 50,000 labels.
