Common causes

  • 1Mechanical jam hindering motor rotation.
  • 2Electronic failure in the motor drive controller.
  • 3Premature wear of the traction roller bearings.
  • 4Obstruction caused by accumulated debris on the motor shaft.

Solutions

Diagnóstico rápido

If the printer attempts to start its rotation and immediately stops with an E005 code, the motor is encountering resistance higher than nominal, or control signals have been lost.

Solución paso a paso

  1. Remove all media (ribbon and labels) from the print path.
  2. Rotate the roller manually to check for any physical resistance or foreign objects.
  3. Inspect internal connections for the motor if you have advanced technical knowledge.
  4. Perform a deep power cycle by leaving the unit unplugged from the mains for 5 minutes.

Prevención y mantenimiento

Avoid overloading input trays and ensure ribbons are correctly tensioned. Minimal lubrication of external plastic parts and monthly cleaning of the roller prevent unnecessary motor strain.

Cuándo llamar a un técnico

If you hear metallic noises or feel extreme resistance while turning the roller manually, the motor bearings have likely failed internally, requiring professional repair.
