We had that problem on our oldest (and most heavily-used) LaserWriter.
I didn't think the things that gouged up the fuser assembly were the
rubber things though, there are what look like three metal triangles
(for lack of a better word) that ripped the red coating off of 3 areas
on the fuser.  This resulted in output that wasn't well-fused in these
areas.  The didn't rebuild the engine, but they did replace the fuser
bar and tinkered around with the fuser pressure settings a little.
The printer seems to be doing ok now, almost 70,000 pages since we had
a logic board replaced a while back.
