Look at the back of machine and make sure air ducts on the rear frame (inside the Main Drive Unit) are not blocked. ITB over life also should be changed.

That diagonal pattern usually indicates developer drainage. Did you swap the dev unit first and without other parts - and was the problem gone for a while?

If that was the case you probably have to change it again - a faulty drum unit or hv can cause this problem over a period of time.
