yup replace the drum unit...
as far as the question about organic drums... yes there are several type of non organic drums.... they are usually in higher speed/production models that can go 600k - 1mil pages. selenium drums required 'polishing' with a special powder and they could produce a poison (arsenic?) in the sludge removed from the polishing procedure ... organic drum are more for the lower end machines.
Yes the mark on the drum matches up with the location on the paper (on the edge of the sheet) so that pretty much confirms the drum and that wear spot/scratch on it is causing the print defect.
Luckily if I rotate the paper so it is LTR-R, the spot is then out of the paper path and prints look good. That's the temporary work-around for this.
When I first started doing this there were Selenium Tellurium drums, Arsenic TriSelenide drums, and Cadmium drums. Then came Organic drums and Silicon drums, and that's mostly all that you'll see now.
I remember hearing about somebody who died of Selenium poisioning that worked in one of the drum manufacturing facilities. But it was incredibly unlikely that a tech could get a lethal dose of Selenium just installing drums.

If you'd like a serious answer to your request:
1) demonstrate that you've read the manual
2) demonstrate that you made some attempt to fix it.
3) if you're going to ask about jams include the jam code.
4) if you're going to ask about an error code include the error code.
5) You are the person onsite. Only you can make observations.

Those are repeative you know. I like to print it on A3 paper and measure the distance then divide the result by 3.14. Then measure/compare some more diameters
Often drums and heat rollers have very similar circumference so precision is important just rolling paper and comparing with cylinder inside machine isn't enough.

Ok, I changed out the black drum, and the repeating black spot went away. I ran color calibrations last night and all was well.
Now today the users are saying the colors are not properly aligned. They're trying to run the Auto Correct Color mismatch and it is saying that it was cancelled and to try running it again, and if that fails to call Support. So they're calling me.
Any ideas what might cause that to fail? Obviously it could be something to do with the drum just installed, but would I need to go back there and open up the machine again? If so any recommendations as to what to look for? All seemed fine when I left it yesterday.
Thanks.
