DSc-435 black lines in middle of page

[manna]

Dear All Once again i am here over one of my DSc-435 in middle of page
some times black lines appear sometime it light sometime it is dark.
I replaced all PCU/DEV.Cleaned full scanner mirror's.It is erratic while
printing counter.Making copies or even taking print outs.
Only i found just above cleaning unit one silver roller, over that roller toner circle. I cleaned that area also but i am not sure that it is permanently i resolved my problem.
Can any help in this regard.

Thanks

Sounds like you're describing poor cleaning of the transfer belt. I'd replace the belt and the cleaning blade (or entire cleaning assy).

ok, few things first.

where are you from? as you say your from bermingham? you call yourself robert (very british name) yet you write with broken english so i'm a little confused I know brummies speak funny at times

onto the problem is the line from lead edge or a line from rear to front spaced out. If its from lead edge i.e. going left to right then check the fuser (belt inparticular) for seperation claw marks if its spaced out lines look for a roller or better still post a copy sample.
