    it looks like you are going to have to replace the MFP board.
    I had the same issue with a C353 and it ended up being the board.
    if you have a spare, take it with you.

    Well i had my suspicions so the first thing i did was changed MFP board and what i did was i took it and installed it in other C450 and the other one worked fine without any errors, codes or change in print quality but when i put the very same board back on that machine, same problem started again, so i tried to took the good board out from my own machine and installed it in this one, the result was the same so i believe its totally something else.

    If the pattern runs through the image voids, I'd look at the laser. =^..^=
    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.

    Best to start a new thread and post samples so we can see your problem. A lot of folks will see the start of this thread, not notice the dates, and start giving ideas for fixing the original issue.
