Solutions

Diagnóstico rápido

If the error appears, open the main access panel. Check if the print head moves smoothly. A quick diagnosis involves checking the encoder strip for ink splashes or debris, which can cause erratic movement.

Solución paso a paso

  1. Disconnect the printer from all power sources.
  2. Carefully inspect the print path for loose paper or foreign items.
  3. Clean the encoder strip with a dry, lint-free cloth if reachable.
  4. Reconnect the device and observe if it cycles successfully.

Prevención y mantenimiento

Keep the printer in a clean environment to reduce dust intake. Using only genuine consumables prevents ink leaking into the internal components, which is a major cause of sensor failure.

Cuándo llamar a un técnico

If the print head carriage shows resistance or the error persists, the underlying issue might be a failed motor or logic board, requiring professional repair.
