  1. Power off the printer completely.
  2. Clean the area with optical sensors for the ADF with a dry cloth.
  3. Verify that the rollers have no stuck labels or paper scraps.
  4. Restart the unit; the scanner should perform a movement calibration.

  1. 1

    Clean ADF sensors

    Use a clean cloth to remove dust from the ADF sensors.

  2. 2

    Power cycle

    Turn off the device, disconnect from the network, and wait a minute to restart the scanner.

    Check paper

    Make sure the paper loaded in the ADF is not wrinkled or stapled.
