I'm sure your method is more "complete" - but I use compressed air to blow out the radiator screen on my 4110. Been a while since I've been near a 2810 so I'm not sure on the clearances and such, but it seems like you may be able to do the same thing so you don't have to remove your FEL. Granted, it takes me a little stretching & contorting /forums/images/graemlins/crazy.gif, but only takes a few minutes. Perhaps you can get an extended “wand” so you wouldn’t have to contort so much. (Hey, maybe I’ll do that too instead of using the short version I currently have! /forums/images/graemlins/tongue.gif)
