Common causes

  • 1Dust buildup on optical sensors.
  • 2Adhesive residue from scanned documents.
  • 3Sensor misalignment.
  • 4Internal communication failure in the feed circuit.

Solutions

Diagnóstico rápido

The error locks the machine's operation, preventing any feeding. If you suspect sensor issues, inspect the feed path for visible obstructions. If the path is clear but the error remains, the sensors themselves are likely masked by dust.

Solución paso a paso

  1. Shut down the device and unplug power.
  2. Open the upper cover.
  3. Clean the sensors using a soft, dry, lint-free cloth.
  4. Use compressed air to clear deep-seated debris.
  5. Reset the device by cycling power.

Prevención y mantenimiento

Avoid scanning documents with labels or adhesives, as they leave residue that quickly fouls sensors. Weekly cleaning is recommended for high-volume environments.

Cuándo llamar a un técnico

If you have performed a thorough cleaning and the error persists, there may be internal circuit or sensor component failure requiring service.
