So I think I cleaned it up a bit I'm not getting the crazy streak (well as bright as it was) no more but now getting those yellow drops I'm wondering if it's the yellow developer or magenta I'll try the yellow developer unit (which I bougth a new one)
On the last images it looks like missing magenta, so sorry that I insist but I think it is a debris in magenta developer housing that make the magnetic brush not be uniform.
Issue still there in fact for a while seemed to have disappeared
we were getting multiple ines, faded, ut multiple magenta lines
we sorted that out with the drum
but now getting this yellow/clear line on prints
I switched the drums around and ran the drum test file sent.
The Black seems ok.
Ironically enough that's the only drum I ordered.
I used an old drum in place of the magenta and yellow and the problem still persists.
Take out the yellow developer housing cover to see if it is a line on the magnetic rolller. This means it is a debris on developer.
If not, it is possible to have a dirty Laser window. To see this take out the drums,drums cariadge, extend the transport cariadge, take out the IBT assy and with a light look better at the Laser's windows and if you see some dirty clean it with a linth free cloth.
