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

[Barry97]

Does it happen on all paper sizes? What size is that in your photo?

It is every size. On all the trays.
The paper size was 11 x 17

I even tried the firmware update. Still wavy!!!!

Looks like either high temperature in the fusing unit or a motor is going to slow.


EDIT: bad temperature on the fusing unit could be because of hot enviroment. try to move the machine to a cold room, for example a kitchen or bathroom and test it there.

I am in a workshop. Always at room temperature in the shop.

And did you remember since when this started? All of the sudden or graduatly?

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.

Its not about wear. Did you do a tooth count to be sure? Like asked if it started over time its not that. But...

It happened all of a sudden. I am still in training.
I have replace the fusing drive.
Changed the fusing unit too.
Replaced the exit and reverse unit.
Transfer roller.
Cleaned the rollers changed the paper.
Tried to change the speed and the temperature.

And the ripples start after the fusing unit. tested a newer fusing unit.

Still does that ripple/wavy printout.
Just wondering if there is a problem with the frame?
Can this caused by bending of the frame?

Remember what was charged before it started that is my best advice.

Is that a C454 or C454e you are working on?
