with high speed and duty cycle.

Media Drive Assembly
The Media Drive assembly controls each Roller in the paper transport system. A gear train
located behind the Motor connects it to the Exit Rollers, which are built into the Exit Module.
Gear trains located within the Media Drive Assembly, along with two Clutches and a Solenoid,
allow the Motor to control the Pick, Takeaway, Duplex, and Deskew Rollers. A unique Swing
Arm allows the Pick, Takeaway, Deskew, and Duplex Rollers to rotate in the same direction
regardless of the direction the Motor is rotating.
