I am 100% sure that the K drum is the problem and you have to change it

But image defects on each colour looks the same that's why for at least that fault, look at ITBU

I tend to agree with you, but not to the 100% stage. Machines can surprise you, and I am rarely that certain of anything anymore. =^..^=

As we all know, 1st transfer for black is always engage in ITB w.r.t. drum. hence it could be ITB Or Black Drum Unit. Also it would be appropriate to check Developer Unit.

Hope this helps.
