    Oliver,

    When scanning the Kodak Gray Scale target, I've seen where its darker on top
    and lighter on the bottom of the gray scale target. I get inconsistent scan.
    Do you know if the lamp maintain it's brightness consistently for all scans?
      Does this build fix this problem?

    Thanks,
    Kym
