You have to replace the drum and developer at the same time. I ran into that issue a while ago on a 350 that only had 25,000 copies. It had a grayish background and I had to replace the drum and developer, reset the counter and run F8. It was fine after that.

Make sure the seals at the ends of the mag roller are in good shape. Also make sure the DS rollers are not loose and wobbly. If one or both of these problems are evident replace with a new dev unit.
Hope this helps

Take drum unit off dev unit and check drum shaft mounts. I have seen shafts break, very easily done if you twist drum too much when mounting on dev unit.
