Hi William, I found that cleaning the rubber wheels with methylated
spirits restored the "tackiness" to them very well. Although they do
wear and may not be able to get sufficient purchase on the paper any
more, in which case you will need to replace them.

Americans should read fuel alcohol or "methyl
hydrate" for methylated spirits.
