Principles of Operation
Revision - Xerox Internal Use Only
The End and Side Guides adjust to different media sizes by moving them to contact the
media edges and hold it in position. Size Switch actuators, located on the tray, are set by
the position of the end guide to indicate loaded media size.
• Sector Gear
The sector gear engages the lift gear on the Lift Motor shaft to raise the bottom plate.
• Bottom Plate
The Lift Motor through the lift gear and tray sector gear turn the lift shaft raising the bottom
plate which causes the media to contact the Nudger Roller. This activity is monitored by
the Lift Sensor. The bottom plate also actuates the media level indicator.
520-Sheet Feeder Feed Assembly
Optional trays are functionally equivalent in terms of the feeder mechanism that moves media
from the tray into the printer. The driving force from each feeder’s Feed Motor is transmitted via
a gear assembly to the Feed and Nudger Rollers, moving paper from the tray into the printer.
