    Light copy's when copying off glass (Prints from PC fine)

    The copy's off the glass are noticeably slighter lighter than the prints. If you adjust the density to dark they look fine. Is there a way to adjust the exposure density in service mode to just affect the copies off the glass and not the prints ? Thanks so much for any help !!

    Usual culprit for light copies is dirty optics...I'd start with cleaning the lenses and mirrors and see if that doesn't help.

    ....other than that, I'm not as familiar with Brother products, so see if there's something here that may give you some direction.

    It may be pertinent to know what model you're working on. =^..^=

    If you'd like a serious answer to your request:
    1) demonstrate that you've read the manual
    2) demonstrate that you made some attempt to fix it.
    3) if you're going to ask about jams include the jam code.
    4) if you're going to ask about an error code include the error code.

    it's not easy top remove glass... you have to remove ADF and complete scanner. It doesn't have mirrors on most Brothers

    It is dirty optics combined with old(weared) drum.
    Digital machines are good to compensate image for dust in optics, but when drum count gets high numbers on Brother I believe that's the result. Replace drum unit with new or used but with few prints and you will see the difference.

    Never argue with an idiot. They will drag you down to their level and beat you with experience.
