At first light image the problem fixed when i replaced toner hopper and add new toner (not geniuin bua i use this toner with no problem) .
When this bottle ended customer added a geniuin toner and now there is a dark background (no dark lines, opc is new) rihgt after toner replacement. It looks like problem in developer (machine made about 270K copies).
Any idea?

Hi there!
Use of both toners (generic, then OEM) killed your developer. Time to change.....

You have a filming on the development roller. It is a common problem with all 35/45 and 40/50 ppm models. Not only do you need to replace developer but you need to clean/replace the development roller and thoroughly clean the entire pcu of any and all toner residue to avoid contaminating the new developer.

If you have found a generic toner that works, never mix a different toner with it. All toners are not the same and the settings you have already made will not work for both toners. I agree with Zeldaman and Slimslob, clean the mag roller and replace the developer.
