Dell 5210n Mono Laser Printer - Manual (Page 92)

After you carefully unpack the output expander, install it immediately; otherwise, the edges of the mounting brackets could damage tabletops or fabrics.
1. Remove the top cover from the printer, finisher, or high-capacity output stacker.
2. Slide the plastic bracket onto the static brush holder, located on the bottom of the output expander.
3. Insert the mounting brackets into the slots on top of the printer or print media handling option. Make sure the output expander is positioned securely.
4. If you are mounting the output expander on the printer or another output expander, attach the wire bail. Place the tips of the wire bail into the ends of
the plastic bracket so that the bail curves downward.
The wire bail rests in the output bin of the output expander below it, or in the standard output bin.
