5655 two sided dark copy

[mrfuser]

Ok client can run one sided all day fine. Start to run two sided and they get darker back ground as it goes. We replaced feeder and drum unit and same result.

Only happens with multiple originals, single two sided is fine even with multiple copies run of one original!

any ideas?

What I will do first.

-very good scaner cleaning
-replaceing scaner pwb and exposure lamp
-sw upgrade!
-IOT pwb

PS
is the same problem if you make two sided copies/scans from glass,or if you make two sided prints?
