Ricoh 3228c image defect

[Copier_Guy]

Could anyone give me an idea what may be causing a Black Block to print on the center of the page for this printer. I'm going to a client that has this problem and would like to expedite my troubleshooting process. Any help would be greatly appreciated.

Thanks All

Possibilities that spring to mind.

1. A small scatch on the black drum (PCU).
2. A small tear on the fusing belt.
3. A leaking black dev unit.
4. Dirty optics if it's on copying only.

Thanks for the response. I was thinking it might be density patch issue, but it might be a label or something that got adhered to the drum. I'll let you know after I get there and check it out.

It was actually a large Black Splotch going across the page. It turns out the Black Photoconductor Unit has seen better days. Needs replacement.

Thanks DaZ for the input.
