Abstract
Paper moving rollers, for use in printer or duplicating machines, particularly those using an autocompensating feed system, are disclosed. These rollers have a long effective life and provide reliable single feed of paper while minimizing double and multiple feeds. The rollers are made from a rubber composition comprising isoprene rubber, at least one ozone-resistant rubber, such as EPDM, and a rubber curing system substantially soluble in the rubber mixture. The process for moving paper in a printer or duplicating machine using these rollers is also disclosed.
