Random Black Band- Xerox Versant 80

[rwyeth]

In a run of 2,000 sheets, three sheets came out with this black band across the sheet (edge to edge). The three affected sheets occurred randomly toward the middle of the run, a couple hundred sheets apart and not the same place on the page. Does anyone have an idea of what might be the cause...random drum or developer issue...processing/imaging issue?
Thanks,
Robert

Drum failing. Put a new black drum in.

Assuming you are running short edge feed. If not, this is something else.

Yes, it was short edge feed with the bottom of the page being the lead edge. I think the drum still shows 50% or so. But, I'll give that a try.

Pretty sure it's the drum.
