Hi everyone. I cannot find the problem with this 901 that intermittently has a backgrounding issue. In the dark area, you can see a ghost image of the previous page. Copier has 4.1 million clicks. I have replaced developer, drum, 2 drum blades, developer bearings, and it still does it occasionally. The erase lamps come on as they should. I do have excessive toner scattering from dv unit. I have scrubbed and cleaned mag roller. I have re-gapped, and cleaned dr blade. I have done 2801 and 2962. I am not very experienced on these Ricoh boxes, so any veterans, please reply! Thanks
