Installing a duplex unit The duplex unit attaches under the printer, below
the standard input tray and above any paper
drawers.
Refer to the Lexmark T620/T622 Publications CD
for details about using the duplex unit.
1 Place the duplex unit on top of any installed
paper drawers, or the table or printer cabinet
where you plan to use the printer.
The tab, peg, and holes on top of any drawer
help you seat the duplex unit so the edges
are aligned properly. Make sure it is securely
in place.
