Common causes

  • 1Adhesive buildup on the optical sensor.
  • 2Media path obstruction preventing correct label detection.
  • 3Corrupted firmware initialization.
  • 4Incorrect media settings in the driver configuration.

Solutions

Diagnóstico rápido

Error err-01 is identified by a solid or flashing red light. If your printer doesn't feed labels upon startup, it confirms a sensor synchronization issue.

Solución paso a paso

  1. Power cycle: Turn off the printer, unplug it for 30 seconds, and power it back on.
  2. Clean sensors: Use isopropyl alcohol to clean the label sensors and remove adhesive residue.
  3. Manual calibration: Hold the feed button until the LED blinks twice to calibrate the media sensor.

Prevención y mantenimiento

To prevent this, keep the media path free of dust. Use quality direct thermal labels to avoid glue residue on internal rollers. Regular cleaning cycles will extend the unit's lifespan.

Cuándo llamar a un técnico

If the calibration procedure fails multiple times and the red light persists, the internal optical sensor may have failed and requires hardware replacement.

Frequently asked questions

This error typically indicates that the printer's media sensor cannot detect the gap or black mark on your labels.

It is usually a synchronization error that can be fixed by cleaning the sensors and recalibrating the media.

Always use high-quality direct thermal labels to prevent adhesive buildup on the print head and sensors.

Perform a basic cleaning of the sensors and print head every time you replace the thermal label roll.
