What is "shimming" a jointer?

I've seen several people having to shim their jointer when setting it up, but I
don't know what this means. I think most of the comments were in regard to a
model with table extensions, specifically the Sunhill 6" jointer. What is
shimming, why is it necessary, how is it done, and is it difficult?
This refers to placing shims between the mating surfaces of the central
casting of the jointer (the part that houses the cutterhead) and the infeed or
outfeed tables. This is done to correct misalignments (e.g. a sagging table)
or to remove play in the adjusting mechanisms. It's done by loosening the
adjustment far enough to allow placement of a thin piece of metal in the
appropriate spot in between the mating surfaces. How thin, and what is the
"appropriate spot", depend on the problem that needs to be corrected. Is is
difficult? Dunno. My jointer was good enough right out of the box that it
didn't need any shimming. Looks to me like the hardest part is figuring out
how much to shim, and whe likely a lenghty trial-and-error process, not
difficult but a PITA.
