the following a4 empty exposure glass copy (white) is dirty and exactly two bar of this shape appeared on drum surface one in near center (scanned picture on a4) and other near left arm charge roller (appeared on a3 copy)

what reason exist for this problem?
i Rebuilded the PCU with a new cleaning blade(staitionary blade) and brush and insert old blade 2(moving blade) in opc.
i have two bushing on both side of charge roller arm and cleaned both
Is it possible Bin the blade solve this problem that has the two springs on it, it causes more hassle than it's worth.
sometimes i Remove the opc unit and clean and rebuild it with the same parts copier quality is good but recent time that i do this , this problem is created
also i clean transfer belt and blade ,
whether i put charge roller(cleaned with cotton and alcohol) as dry or grease with oil?(what type of oil?)
my setting
charge roller bias :
sp2001#01 (default = 1500 v current= 1560) sp2001#02 (default=250 current=250)
two suggestion:
1- remove moving blade from opc unit
2- Remove the drum, clean the contact surface of the front and rear charge spring plates for the charge roller (slightly bend the plates up to ensure a good contact) and put the drum back in. look at the charge roller and make sure it is sitting flush against the drum.

"I'd start with vacuming out the engine unit. Remove the drum, dev and laser unit. Give it a good clean. I'd also change the developer powder.
Whenever anyone asks me to look at anything in that range. The first thing I reach for is my toner vacume.
Sorry this question, by any chance did you change the filter unit of revelation.
Once happened to me and i have a filter out of the place and have this symptom
The Vacuumed up filter from the dev unit (ricoco) gives a white band down the centre of the copy.
you could have a problem with a damaged seal between the drum and dev units. replace the seal and lock the units together with a self tapping screw (Next to the seal) to prevent leaks.
