Yes I did the whole PM kit. Bothe the old and the new DV units do this defect. The pattern just changes a bit when changing between the two. And yes I did run 140 when I installed the PM kit.
Wow. That’s messed up.
Is it possible to stop an image half way thru transfer to see if that is what’s on the drum.
I’m also leaning towards Dev unit…..but if it’s new, what could it be? The blurr on the edges are interesting
So to confirm
Old dev and new dev produce exact same images
You have done a complete PM kit
How many prints on machine?
I’d probably try a HVT unit next and confirm all HV contacts are clean
All the best. Keen to know what is causing it
The last time I saw images like this, I was filling in for another tech. He told me he had installed a developing unit. It turned out to be a used developing unit ... with the same exact issue. =^..^=
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.

This may not have anything to do with his problem, but I have found if the prints for U410 and U412 and U469 error out, one may need to check that the paper is centered as it comes out of the drawer/cassette.Originally Posted by ntbann
This can be done with U034 Adjust Paper Timing Data > LSU Out Left > Use the System Menu button to get to the copy screen and pick the cassette to be adjusted. Press Start to print a test page (best to use 8.5x11 paper for this adjustment). Fold the page in half to see what way to change the number for that drawer. Press System Menu button to go back to the adjustment screen and change the value for the desired cassette. Press start to lock it in. Press System Menu button and make another test sheet. Fold the page in half and look for a change. Do this till the center line is in the fold.
I do this to every machine I come across that I have never seen. I do this because it insures print outs for calibrations are properly centered so the machine will read them properly. Too many time I have gone behind other techs that told me they didn't do the calibrations because "the machine gave a funny error when it scanned the sheet. So I blew it off". I would go back, center the page and the machine would read the pages just fine.
Sorry to get off topic.
The quote triggered me.
Yes I promise it is a new DV unit. I unboxed it. Tried the THV today along with the plastic housing that contains all the springs. Still the same. Have a Main PWB coming on Monday.
The units that were put in, are they new units? Or t/o for testing purposes?
brand-new.
Just a thought on the HV unit. Did you depress each spring physically to check for internal damage to the springs? some have a catch in them and make intermittent contact. Their springiness ( technical term lol) isnt consistent.
I swapped the housing with all the springs.
