    What about clutch CL8? Are you getting 30-03 jams?
    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.

    It's been afew years since I was in the field, but I seem to remember this as a common problem on anything with a 2nd transfer roller. I think replacing this solved the issue.

    @tsbservice,

    yes, on the picture in the attachment, it`s A3-paper. That`s the best way to see it. However, the problem also exists on A4 or A4R.
    I tried to change the setting from -20 to +20 in the fusing fixing speed, but unfortunately without success.
    The problem occured suddenly and now every copy/print.
    Good Morning.

    All the obvious has already been said. I would check the fusion loop sensor.


    may have been broken by time of use or improper removal of paper.

    @ emujo2
    I have just installed a new tranfer roller, unfortunately still the old problem!

    @ blackcat4866
    I replaced the whole Fixing drive assy! In this assy there is a new CL8. no jam 30-03 occured.

    @ Synthohol
    the change of paper type to thick1 or 2 and Firmware update are also unsuccessful.

    Hi looking at the copy out the flat bit before the wrinkles start looks like a similar distance from reg rollers to fuser
    i know you said "The registration roller drive smooth (all 4 bearings are oiled)"
    i would replace those bearing on both registration rollers and see if there is any improvement.

    Re: C454 - Paper comes out curly (approximately from the half)

    Now I've changed following components:

    vertical Transport assy (which includes the paper loop sensor above the transfer roller)
    both registration rollers and bearings
    registration actuator
    CL6 from the main drive assy (which drives the registration rollers)

    The problem still exists!!! the paper Comes out curly!!!

    Does the distance from leading edge to the first curl is the same on different paper formats?
    Can't remember but did it curl from bypass tray?

    I would try to cheat side door and figure a way to run copy without jamming up to the fuser to see paper drive.

    Could be faulty control from a shot motor driver. Try control board.
    Whatever
