Cleaning the Rubber Roller
Another condition that can inhibit the proper reading and feeding of cards is when the rubber roller
(Figure 12) becomes contaminated by the graphite residue from previous card readings. We
recommend periodic cleaning of the roller to insure proper frictional contact between cards and the
roller. Also, by regularly cleaning the rubber roller, you can avoid the transfer of graphite from
the roller to the next set of cards.
