Make sure that the toner recycling mechanism that sits on top of the developer unit (where the pipe ends) is working properly. They are cheap to change out and only three screws.

Also, I sometimes round out holes the recycling pipe (on the front of the drum unit) where the mounting screws go just a little bit and add a bit more pressure to make the two joint gears mesh better. I don't have any problems after that. I don't know if it's a slight manufacturing flaw or not, but it only needed to be done on a few machines.

Also check that the entire wast toner system is not clogged - these machines sometimes like to clog up right at the waste bottle - what a mess...

Have you fixed the blurry copies yet? It might be something else causing the blur, but just happened to show after you changed the dv.

Check to make sure that the dv unit is fully seated and behind the little pin in the front (you'll see it).

The drum flywheel could also be starting to come loose. And check to be sure the correct toner is installed.
