Solutions

Diagnóstico rápido

The screen displays 'Head Lift' when the printhead is in the raised position. Check the side lever. If it appears closed, the physical contact sensor may be obstructed or dirty.

Solución paso a paso

  1. Secure the lever: Push the printhead locking lever down until you hear it click into the closed position.
  2. Visual Inspection: Ensure no label scraps are trapped between the printhead and the platen roller.
  3. Sensor cleaning: Use compressed air to blow out any dust from the lever switch area.
  4. Power Cycle: Turn the printer off and back on after ensuring the head is correctly closed.

Prevención y mantenimiento

Never force the lever. Clean the platen roller with isopropyl alcohol monthly to ensure the printhead closes evenly and maintains contact.

Cuándo llamar a un técnico

If the lever is correctly locked but the error persists, the internal micro-switch may be faulty or the pressure spring worn out, requiring professional service.
