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.

I tried everthing here. I am still getting that wavey print out on paper. It does not Jam just does the wavy printout. I even changed the fusing motor. The outcome is the same with the other trays on the machine.Originally Posted by Laserbeam

Same procedure for you: Stop the Machiine mid-Job and check where the paper turns curly.
have you made sure ALL the gears are correct on the reversal unit

I replaced the whole unit. print out still curls. There is no paper jam. While it is printing I did open to see where it starts, it happens after it passes the fusing unit.

this is what i get.
I checked the gears and they all are fine. No wear on them.

Re: C454 - Paper comes out curly (approximately from the half)
I even tried the firmware update. Still wavy!!!!
Does it happen on all paper sizes? What size is that in your photo?
