I have exactly the same problem on C5501,
I have recently done a first PM on it. (no line for first 10,000 odd prints)
Yesterday when at the customers I swapped the yellow drum with cyan just to see if problem persisted (I noticed the problem seemed to be with Y) and the line disappeared, feeling very happy with myself I then ran about 10 prints and the line came back.
I then checked the corona and there was a little white mark on the end block (only just replaced corona's with PM kit) I then cut back the end block and swapped the drum again (magenta drum this time) all seems to be fine know.

Hope this helps.
