Bizhub C451 - Paper curling

[ncbabak]

I have a customer with C451, which is printing and copying good but the output is wavy and some times paper jam.
Checked the registration roller cleaned and Also checked the duplexer, paper dampness etc.
I don't know what I am missing.

Good thing to check. Those gears are known to wear. Especially the one exit gear will hollow out in center and gear is flopping around. I've seen some so bad couldn't believe it would even eject the paper.

Check the heater roller with the flexible spring, may have had a paper rolled on it, also check the gear clearance at the meshing point with the gear situated at the upper part of door. Thanks.
