Solutions

Diagnóstico rápido

This error is purely mechanical. It indicates that the printer's latch sensor is not receiving a signal that the printhead is locked in place for optimal print pressure.

Solución paso a paso

  1. Release the lever and lift the printhead slightly.
  2. Ensure there is no debris inside the closing mechanism.
  3. Firmly close the lever until it clicks into the operational position.
  4. Check the display to ensure the error clears.

Prevención y mantenimiento

Check the printhead latch for loose screws periodically. Keeping the area clean prevents small pieces of label backing from causing false sensor triggers.

Cuándo llamar a un técnico

If the latch closes but the error remains, the physical sensor switch inside the chassis may be damaged.
