4036-501 DADF Paper Path Components The DADF paper path is made up of transport rolls and paper sensors. • Nudger Roll (subassembly of pick roller assembly) The roll moves paper toward the feed roll utilizing a combination of mechanisms between the rotation of the roll and the friction of the separation pad. • Feed Roll (subassembly of pick roller assembly) The roll moves a sheet of paper toward the registration roll utilizing a combination of mechanisms between the rotation of the roll and the friction of the separation pad. • Registration Roll The roll moves paper toward the large roll by its rotation, after the skew correction. • Large Roll The roll moves paper, by its rotation, toward the platen glass of the scanner for scanning, and then moves toward the exit/reverse roll. • Exit/Reverse Roll The roll moves printed papers to the tray or turns over and sends the paper in the direction of the large roll to duplex. • Exit/Reverse Solenoid This solenoid separates the reverse roll from the upper exit roll. 1-22 Service Manual
