i have a problem with banding in feed direction on any weight of paper , this shows it's self when solid colours are printed, looks like roller marks but can't see any rollers that can be causing the problem..it doe'nt matter which papertray is used including bypass unit..please help!

Can you share a scan of the thing with us?

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).

Thanks abilashvk

Mr Who , i can't scan image in as doe'nt show up the marks

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

Good luck with that.
