    This looks like broken illumination correction. I don't know about
    this scanner in particular so I'm guessing, but...

    If this scanner has a self-calibration step, it probably uses a white
    reference that might have been damaged. If the profile is calibrated
    at the factory, the sensor might have slipped, causing the profile
    to not match the device.

    How 'bout the light? It looks like the artifact is outside the focal
    plane, so maybe the lamp itself is damaged?

    Whatever it is, it moves with the sensor/lamp so it is not the bed.

    A spot on the sensor?
