    paper in letter portrait direction shadow from top to bottom ( not lead to trail ) varies from 1/2 " to 1 " on lead edge on back side of single sided copies.

    Do you have an image? =^..^=
    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.
    5) You are the person onsite. Only you can make observations.

      I do not . It is a very light shadow so I don't think it will show up on a scan anyway .

        If it is on the backside of a single sided copy, I would look at the secondary transfer roller to see if it is not being contaminated by a toner build up.

          My bet is the pipe assy that is blocked so the transfer unit cleaning is filled with waste toner that starts to build up on the transfer roller.
