Common causes

  • 1Physical obstruction by adhesive residue on motor shafts.
  • 2Motor fatigue after heavy duty cycles.
  • 3Incorrect sensor setting in the control panel menu.
  • 4Ribbon sensor failure due to dust accumulation.

Solutions

Diagnóstico rápido

The error is confirmed if the motor makes a buzzing sound when starting, followed by a system freeze. If this happens, the issue lies in the ribbon mechanics rather than the print head.

Solución paso a paso

  1. Power off the printer using the main side switch.
  2. Remove the ribbon and label media to inspect the path.
  3. Check that the rollers move freely without manual obstruction.
  4. Reinstall the supplies, ensuring correct ribbon tension.

Prevención y mantenimiento

Use compressed air to clean the ribbon sensor monthly. Avoid low-quality ribbons that create excessive friction.

Cuándo llamar a un técnico

If the error persists after cleaning and rebooting, the internal motor drive circuitry may have failed, necessitating professional repair.
