Thank you!

That is a good Tip for me, i recently bought a replacement for the upper  
pickup roller (very cheap on ebay nobody wanted it), but this way i can  
also fix the lower roller on my IIID.

I tried sanding the original roller but it never worked any better,  
glycerine did no good either,

The "cracks" are "stock" with those rollers, they are there as friction  
ridges (like one your hands and feet) to make it grip. But the surface  
wears down and goes shiny as you observed and it just won't work properly  
any more.

BTW someone recently suggested a strange chemical to do just this roller  
repair, it was called something crazy like oil of wintergreen or  
something. Now my chemicals shop sells sea foam dust and dragon blood but  
i don't think they have heard of that wintergreen stuff. I looked it up  
and it is methyl salicylate, but that don't show up on their inventory  
list either, maybe it has another name i'm not aware of.
