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.
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
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.
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)
