    Re: Black copy

    You've try almost everything, are you sure the parts you've test are all good? Did you test it one by one?and regarding black copy there is a totally black copy, and black copy with an image. Try to check if your mirror is reflecting the light at the middle of the lens.

    process of elimination

    if your network prints are good /
    and your copies from the glass & df have solid black over the image = OPTICS ISSUE
