Also make sure that the developing unit isn't dumping developer at the front, and sanding the drum surface. I ended up changing out a black developing unit for this. =^..^=
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.

you mean do all the following
HV Board.jpg
or is the one in the back Frame and how do i check the voltage?
I'd start with the HV board circuit not the HV contact plates. It is a lot faster. You take the rear covers off and side panel where Network and USB ports are + the whole chassis cage block (MFPB+PRCB+HDD+SSD) Behind that block you'll find HV Board. Replace that one first and see what happens.
How are your other consumables like? ITB and Devs.
I had one magenta dev wrecking lot of K devs and TX belts and Drums till we replaced it along with HV Board and FRB (Front Board)
Firmwares HERE.OK Google! ... will I need Berrocca this morning?
You say you have tried this drum in another machine & it prints good? So you know the drum is not damaged.
Before you replace the HVT try another black dev unit first.
Let us eat, drink, and be merry, because tomorrow we may die!
