I bought a SP15 a couple of years ago. The rollers were/are clean and seem to work fine, but they are shiny and quite hard. However, after reading a recent post on Briarpress about cleaning rollers I wonder if mine are glazed and need to be deglazed (or possibly recovered). Certainly, the rollers are not dull with a mat finish as are the rollers for a Kelsey 5×8 that were recovered recently for me by Advanced Rollers in CA. These rollers are not shiny but are dull and are good bit softer.
