If the error appears when trying to scan or copy, check for paper debris in the feeder path. A 'DF communication error' message will appear. Ensure the ribbon cable between the scanner and the ADF is secure if the device was recently moved.

Solución paso a paso

  1. Power off the machine and disconnect the ADF if trained to do so.
  2. Remove any debris like paper scraps or dust from the ADF input tray sensors.
  3. Check physical connections at the ADF hinge for bent pins.
  4. Perform a hard reset by holding the power button for 30 seconds after unplugging to clear cached errors.

Prevención y mantenimiento

Clean the ADF feed rollers with isopropyl alcohol monthly to prevent jams that trigger this error. Avoid forcing the feeder lid. Keep the scanner firmware updated via the web interface.
