Solutions

Diagnóstico rápido

The error E020 is identified by a noise from the document glass area or a failure to initialize scanning. If you hear a thumping sound when the machine turns on, it means the scanner head is stuck.

Solución paso a paso

  1. Power off: Turn off the unit and check the scanner locking switch to ensure it is in the operational position.
  2. Visual inspection: Lift the document cover and check for any debris along the scanner glass track.
  3. Restart: Reboot the machine so the scanner motor can perform its auto-calibration routine.

Prevención y mantenimiento

Clean the exposure glass with a soft microfiber cloth. Do not manually force the scanner carriage as it can cause belt damage. Always use mild glass cleaning products to avoid surface etching.

Cuándo llamar a un técnico

If the machine fails to calibrate the scanner after several reboots, technical support is needed to replace the scanner carriage belt or the stepper motor.
