What is the most likely culpret causing these black lines (pictured). Olivetti c280 or KM bizhub mf280
The printer has previously had almost everything reset without replacement I think. The black developer is new.

The main lines are 63mm apart but there are others. They are pretty faint and only appear on the printed side (without duplex printing).
The first one is about 3/4 way down the page and the other visible ones are 10 and 20mm from the bottom of the paper.
Thanks for looking...

Here are the consumables, I think most of them are beyond life limit. Someone before me has reset them.
The paper has test printed on it, does that help with the direction? or do you mean how it lands in the tray?

Best way to diagnose problem woud be replace drum unit k first.
You could also try this,remove Y drum unit,remove K drum unit,remove chips from bottom of drum unit and swap them,Y to K, K to Y and try then place them in machine and test is it better.
I hope you understand this.

Update.
A new drum unit sorted this issue.

Now I have another issue. (will it ever end with this thing).

I think I made a mistake by not swapping the chip on the drum. I installed a KM drum (not an olivetti) and it worked fine for 2 days. Now it wont print, but does photocopy. The orange light is on and the printer is offline. Unit is Olivetti MF280, drum was KM for bizhub c280.
I have started a new thread for this issue.
