How to clean the water rollers on Ryobi 3302?

Our water rollers (foam and ductor) attract lot of ink. That messes lot of our jobs. How do you clean the water rollers and how do I keep them clean ? We usually use Polyester (paper) plates. Thank you.

 

Are you running cloth molleton covers? If so rinse them out with hot water at the end of the day or between critical color changes. And blot the excess water off by rolling them in a few sheets of bristol cover stock or washup sheets. If you have a Kompac or crestline the unit should be washed whenever color is changed.
