Solutions

Diagnóstico rápido

ERR-003 indicates an open printhead. If the head seems closed, the sensor is either obstructed or failing to register the latch.

Solución paso a paso

  1. Open: Lift the printhead unit.
  2. Clean: Remove any scraps of paper or tape residue that prevent a tight closure.
  3. Close: Lower the printhead and verify the latch clicks into place firmly.
  4. Sensor: Check for any physical obstruction blocking the printhead closed sensor.

Prevención y mantenimiento

Regularly clean the printhead with isopropyl alcohol to prevent adhesive buildup that interferes with mechanics.

Cuándo llamar a un técnico

If the printhead clicks shut but the error persists, the closure sensor (Microswitch) likely needs replacing.
