  • 1Snapped ribbon.
  • 2Optical sensor obstruction.
  • 3Incorrect sensor sensitivity setting.
  • 4Mechanical wear on the ribbon take-up spool.

Solutions

Diagnóstico rápido

If you see the E-14 code, check for a snapped ribbon immediately. If the ribbon is intact, dirty optics in the sensor housing are usually to blame.

Solución paso a paso

  1. Open the cover and unload the ribbon.
  2. Use a dry cloth or alcohol swab to clean sensors.
  3. Check for any ribbon blockage in the pickup spool.
  4. Perform a system reboot to re-calibrate.

Prevención y mantenimiento

Clean the printhead with 99% isopropyl alcohol regularly. Proper maintenance avoids heat buildup that can degrade labels and ribbon material.

Cuándo llamar a un técnico

If sensor cleaning fails, the sensor board may have an internal electrical fault requiring a factory replacement.

Frequently asked questions

The E-14 code indicates the unit cannot detect the thermal ribbon, suggesting either a broken ribbon or a dirty optical sensor.

Only if printing in direct thermal mode. If using thermal transfer, the ribbon must be present and correctly detected by the printer.

The B-SX5T accepts wax, resin, and wax-resin ribbons. Ensure the ribbon width matches your label media.

Perform sensor cleaning every time you load a new roll to prevent thermal residue buildup.
