    These machines are well known for dumping toner. There wouldn't by any chance be a large pile of toner in the separation transfer unit? =^..^=
    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.

    looks like a drum or blade problem. check cl unit for backup as well. if its a non oem they last less. same with pm kit blades. also check the erase by the charge. i dont think its fuser. click on his picture in the message to see the issue

    Every 6th page don't make sense. Any internal parts, i.e. drum, fuser, etc causing smudges or marks would be every other page or at most every 3rd sheet. Something don't add up?
