Zebra ZT231XT error 004: Out of media
Zebra ZT231XT error 004 indicates that the printer's media sensor cannot detect labels. This stops print jobs to prevent accidental printing directly onto the platen roller. Proper loading and sensor calibration usually resolve this condition immediately.
Common causes
- 1Empty label supply.
- 2Label media is misaligned relative to the sensor.
- 3Adhesive residue blocking the optical sensor lens.
- 4Calibration mismatch after media type changes.
Solutions
Diagnóstico rápido
If the printer displays 004, it means it's unable to find the media. Check if the labels are properly positioned in the sensor's optical path.Solución paso a paso
- Reload labels: Replace empty rolls.
- Align media: Ensure labels sit in the guide.
- Clean sensor path: Dust often blocks the sensor.
- Auto-Cal: Trigger auto-calibration from the menu.
Prevención y mantenimiento
Regular cleaning of the media sensor with compressed air maintains accurate label detection in dusty industrial settings.Cuándo llamar a un técnico
If the printer still displays 004 even with labels installed and a calibrated sensor, the internal hardware sensor might be broken.Ficha técnica del equipo

Steps to follow
- 1
Check media
Verify if the label roll is empty.
- 2
Align
Ensure the labels are threaded properly through the guide.
- 3
Clean sensor
Clear any dust from the media sensor eye.

Calibrate
Run the auto-calibration feature from the printer menu.
Frequently asked questions
The printer's sensor is not detecting any media, which commonly means the printer has run out of labels or the sensor is dirty.
It is a standard 'Media Out' warning that is easily cleared by reloading labels and re-calibrating.
Standard thermal or direct thermal label rolls appropriate for industrial printing.
Always check your label path for debris and clean the sensor path periodically.
