  2. Clear: Remove any paper.
  3. Clean: Use isopropyl alcohol for the rubber rollers.
  4. Reset: Re-engage the cover and test.

Maintenance and Prevention

Consistent cleaning ensures the ADF performs as expected. Avoid using staples and keep the environment dust-free.

When to Call a Technician

If the rollers are cleaned and the ADF remains dead, the sensor assembly may need internal replacement.
