Common causes

  • 1Adhesive residue buildup on the sensor path.
  • 2Misalignment of media guides during installation.
  • 3Incompatible media thickness for the sensor configuration.
  • 4Platen roller wear leading to uneven traction.

Solutions

Diagnóstico rápido

The paper jam error displays a red alert light and a message on the LCD. If the feed path appears clear, the issue may be due to debris on the optical sensor.

Solución paso a paso

  1. Power off: Unplug the machine for safety.
  2. Open printhead: Release the latch to access the interior.
  3. Clear obstructions: Remove any labels stuck to the platen roller.
  4. Clean sensors: Gently wipe sensors with an alcohol-moistened swab.

Prevención y mantenimiento

Use high-grade labels to minimize adhesive buildup. Regular cleaning of the platen roller and sensor paths prevents recurring issues. Ensure the media guide width matches your label size.

Cuándo llamar a un técnico

If the error persists after cleaning and media realignment, the main board or sensor array may require professional diagnostic service.

Frequently asked questions

The error triggers when sensors detect a blockage or failed material advance, often caused by improper loading or accumulated adhesive residue.

Frequent jams suggest a dirty feed path or a misaligned sensor, which can lead to hardware wear if not addressed.

Always use high-quality, authorized B-EX series labels. Cheap materials often leave adhesive residue that triggers false jam alerts.

We recommend a thorough cleaning of the printhead and rubber rollers with every ribbon or label roll change.
