Common causes

  • 1Improper alignment of continuous forms: pins do not match holes.
  • 2Paper residue: small fragments block the optical sensor.
  • 3Worn-out tractors: paper does not feed evenly.
  • 4Excessive pressure from paper guides: friction stops the paper flow.

Solutions

Diagnóstico rápido

This error appears with a flashing red light and halted print carriage. Check if the paper is wrinkled or if the lateral guides are too tight.

Solución paso a paso

  1. Turn off the printer and unplug it to reset the internal sensors.
  2. Open the top cover and manually slide the carriage to the center; check for stuck paper pieces.
  3. Remove the paper by pulling gently along the natural feed path.
  4. Reload the form ensuring the tractor pins match the paper holes perfectly.

Prevención y mantenimiento

Clean the platen every 3 months with isopropyl alcohol to prevent dust buildup. Use only paper with the manufacturer's recommended weight. Keep the exit area free of objects.

Cuándo llamar a un técnico

If the error persists after cleaning and clearing all paper, the paper sensor may be faulty or misaligned, requiring professional intervention.
