Black streak running through prints

[positiveg]

So we are getting this long line appear in our prints.
Now we've changed the developer unit. The IBT belt cleaning blade. Cleaned the lens.
Only thing is the black drum but it just started appearing after we put in the black developer unit.
Any suggestions?
Thanks

aren't you a tech?

looks like the same defect on the paper... did you init the dev unit?

was it a new dev unit or a pull?

looks like a dev unit problem now with the pics.

Re: Black streak running through prints

Thinking it's the charge roller in the drum unit (based on the pattern). May have gotten some developer on it when you replaced the dev. unit.
If you roll up your piece of paper and line up the defects you can narrow it down to certain size rollers.
With the frequent repetition of the marks, i would assume either charge roller in drum unit got contaminated, or maybe a bad spot on the Mag. roller in the dev. unit, or bad seals in that unit.
May be able to clean the charge roller instead of replacing drum unit.

Not a tech that why said will let the Teck check the blade. The dev unit is brand new.
Somwknw told me get genuine parts which have done so. But it's just after the unit was installed getting thar line down the paper

Re: Black streak running through prints

454(without C) and it prints in color
I'm speechless

Just in case it is color unit
- remove K and one of CMY drums
- swap the chips between both drums
- do some tests

Re: Black streak running through prints

Found out it's the drum. We also changed the blade on the IBT. The tech is here and was able to run a few prints stop it halfway then we saw the same pattern that you see the prints.

Thanks. True.
Well it's a C454
And as I showed in the photo there are black streaks. What the tech found after stopping prints halfway and pulling the drum was that the same markings in the drum.
So I've ordered two drums but waiting for them to get to the island tomorrow, hopefully.
In the meanwhile we are trying to see what we can get from this black drum as we have some jobs to run. And the Xerox C75 waiting on parts as well. Delivery heavily hampered by Covid man

Great stuff the tech cleaned out the roller etc we stop getting the mark. But for sure the black drum needs changing as we aren't getting strong black when we print
But for now it should suffice hopefully till the drums get here either tomorrow or Wednesday, thanks much appreciate the help.

Re: Black streak running through prints

Hehe.

Funny stuff.

You could have checked the charge assy on the drum unit.

Going after market can cause some headaches of its own.

Glad its working.

Thanks to the dentist aka Phil we got some info.
Model numbers and other relevant info like total counters and parts life please.

I don't mind playing ' The Dentist ' with end users.. what flames my cookies is having to do it with techs.. guess that's just my service manager side coming out.

Couldn't do it without the rest of you guys tho.
