Page 12: Mechanism
1.Detailed Descriptions Mechanism Paper Feed Separation Mechanism Paper feed is an RF paper feed system. The paper feed unit comprises a Pick-up roller, Feed roller and Friction roller. These rollers are high durability. In the RF system, paper separation is assisted by the resistance of a separating roller with a torque limiter (reverse drive is not performed). -
