The material of the Strippers has been changed from metal to a Teflon-coated resin to decrease the friction level on the Pressure Roller. 2. Springs have been added to press the Strippers against the Pressure Roller. 3. A Stopper Guide Plate has been added to prevent the Pressure Roller from contacting the Paper Exit Cover when it is bent.
