    Description

    This scanning Beckman powers up and passes ALL self testings. However it sees a
    glitch
    with it: the display/monitor is cut off after several minutes while the machine is still on. It needs repair/maintenance before putting into use again.

    Please see the attached photos for details. For buyers convenience, I opened the cover to show its inside.

    the UV source time hrs was wrong: it displays
    109996952.0
    hrs. That means it has been used for more than
    12556 years
    ! (109996952/24/365=12556.73).
