I face problem with my photocopier Ricoh mp 4000 the trailing right edge seems to dirty as in the following picture
I had do the following sequences:
1- replaced the image component (drum and cleaning blade and charge roller and developer)
2- cleaning the magnetic roller to be without any wax
Note : the image component read at least 100,000 copy

After cleaning magnetic roller have you set sp 3-001-2?

Did you set the DV gap @ a tight .35mm?
Are you using OEM toner and DV?

Looks like a dusting problem. The drum sep area is attracting toner dust.

We've seen many MP4000/5000 with dusting issues. Our solution has been to add a new drum ground contact.I'm not sure where we get them. It replaces the contact that touches the bearing with one that touches the drum shaft. We also put on some of that black conductive grease. I hope this helps.

We also use the drum ground tab, can be found at http://www.natrading.com/search/product (#02037006 for the older 35/45cpm)
