How many copies since the PCU was serviced you could need new cleaning blade chare rollers etc preventative maintinance for this machine is 150,000 copies

How is the back of the page?
Have you seen the transfer?? Can be full of waste and causes that durt.
Perhaps a PM came in handy

Rebuild the PCU. That will solve it (Drum, Charge Roller, Charge Roller Cleaner, Cleaning Blade, Developer).

You should do :
1. Check drum, developer and also cleaning blade, if counter reach limit, replace with new one
2. Check what kind toner you used it, original one or OEM
3. Clean transfer roller
4. Enter SP mode , and look up "transfer current" and then "Cleaning", change the value to "1uA" (SP 2- drum)

23032010356.jpgI'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

Oh ye of little faith

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.

my dev filter is missed and i recently change dev (half of 1kg developer type 21 for 700)and rebuilded dev unit without filter
is it possible this caused the problem?

I'd say it's a fair bet.

If I have understood you have no filter in Development Unit????
Almost bet that this is the problem
put the filter and then say something
