Solutions

Diagnóstico rápido

The HEAD-UP error appears on the main screen. If the lever is in the closed position but the error remains, the contact sensor might be obstructed.

Solución paso a paso

  1. Lift the printhead completely by pulling the release lever.
  2. Inspect the base under the head to ensure no label scraps or debris are present.
  3. Close the printhead firmly, applying pressure in the center to ensure both sides lock correctly.
  4. Monitor the screen to see if the error clears automatically upon locking.

Prevención y mantenimiento

Regularly clean adhesive residue from the head sensor. Do not force the latch. Low-quality labels can leave debris that prevents a tight seal.

Cuándo llamar a un técnico

If the error continues after correctly locking the head, the physical contact sensor may be disconnected or faulty, requiring professional service.

Frequently asked questions

The HEAD-UP warning occurs because the safety sensor detects that the printhead is not properly locked, preventing damage during the printing process.

It is not strictly necessary, but it is recommended to prevent accidental movement of the platen roller while adjusting the head.

Use wax, resin, or wax-resin ribbons compatible with your labels for optimal print quality.

Keep the latch area free of label scraps or adhesive residue that might prevent the printhead from closing securely.
