hi,
me not that much familiar with C451 but reducing fusing roller temp., will avoid exit roller marks(if that's the matter) ,but deterioration in print finishing-especially in thick stock(like some what a glossy finish for even KM) as staying long in fusing unit will increase glossiness. Try to reduce fusing transport speed for a better finish in thick stock( customers in this part of the world crave for glossy copies).

Oh, we're talking about exit marks then. Sorry. I thought you were talking about changes in image density.

Good luck with that. :)
