I temp swapped the Yellow and Magenta Drums and there wasn't any change except then magenta faintly covered the whole page now(probably knocked some magenta toner loose in transfer, seemed less white spots in prints though.). Though I only performed 5 test page prints, at least it seemed to confirm dev unit since no change after 5 pages. Also I confirmed line issue was Transfer belt there was no lines on the black drum and the line did indeed have some other colors mixed in on page and ran up to blade.

So I informed them if they want to see fix (outside of any unknown issue were not aware of) a 1.)"A new Dev", 2.) "A new Magenta Drum; for future quality assurance" and then for the secondary dark lines at bottom of page issue a new 3.) "Transfer belt.

Btw I recommended ordering a Black drum for the drum portion(Dev is still magenta ordered). I saw the color drums were all twice the price! I'm assuming drums are universal? I noticed they had a yellow drum in there with a "K" sticker on it so figured that drums must be universal so no reason to not order the Magenta same way. went OEM for quality assurance (mostly due to age of printer model--don't want to get used parts).

Thanks Everyone for your assistance reviewing so I wasn't alone in my efforts, I'll definitely get a free pizza out of it so I'll take it. Be a while for parts to be ordered by them and for them to reach me back to come install, (shipping said 2 weeks) likely due to pandemic but I'd say I think were safe marking closure here.

You've covered all the parts that I would recommend at this point.

One note however... The Black drum will "fit" into a color slot just fine, BUT you MUST order a "Color Reset Chip" and replace the chip that comes on the black drum. The chip is not the same, and the copier will give you an error that an incorrect drum is installed. While I don't recommend it, you could use the chip from the original magenta drum, but this might cause issues with the new magenta dev unit. Chips shouldn't be more than about $10 on average, so I personally wouldn't take the chance of killing the very expensive dev unit ove an additional few $$s.

If you read through all the comments more carefully you will see that after troubleshooting the problem the magenta developer unit was the problem.

Magnet inside magroller sleeve moved...
Magr oller angle does cause this issue on these dev tanks.
Only had this issue by trying to rebuild devtanks.

Thanks for the posts, I'll check them out tomorrow evening. I work in another position and when I get off I'll review above, it's volunteer/charity based for me, likely won't be able to visit their location again till 4:00 CST. I did take some other pictures at the time but didn't want to flood with information on original post. The magenta drum looked okay previously that day and I rolled it to see all sides but didn't check black (doh). But good point on the colors of lines, My higher quality photo I couldn't upload for size limitation I checked seems to indicate that there might have been other colors faintly blended.

The Developing unit looked really messy (edit that's normal I bet), Pages never exhibit changes or any decline in magenta so looks to be dumping okay. Swapping Drums tomorrow (or "technically" later today with the time lol) and we'll let you know on waiting info.

Had a similar case , but in my issue it was white lines on black only- and faint black prints. removed the developer unit, dumped old dev, put new dev, cleaned the drum unit coronas and the problem went away.
In the old dev idid notice tiny specs of white particles.i don't know if it was from paper or what.
