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

    Just a sudden thought, have you tried pulling the paper out when it starts to exit machine and see if it still curled. I remember on a c253 with million odd copies a few years ago at an engineering company they had a similar problem but only 2 ripples on the page and ended up being the exit tray. I ended up swapping with a different one.

    @ Gaffers01

    yes, I had already made this attempt. As soon as the paper become visible, I pulled it out under strong tension.
    But the paper is still curled. Thus, the possibility that the paper exit unit is the cause, is eliminated.

    @tsbservice

    yes, the distance from leading edge to the first curl is about the same on different paper formats. It is also curled from the bypass-tray.

    Problem solved!!!
    The cause was in the reversal unit. Unfortunately, an error encured during my first error Analysis. I had a reversal unit installed from a BH C224.
    However, this unit has a different gear (PN A161819200, 18T). The unit from BH C454 has a gear (A4FJ819200) with only 17 teeth.
    Thus, the drive roller runs too fast and causes the curles in the paper.

    Congratulations on finding that. Only a tech could cause that. Such problems can be very hard to track down. =^..^=
    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.
