CAUTION—TIPPING HAZARD: Floor-mounted configurations require additional furniture for stability. You
must use either a printer stand or printer base if you are using a high-capacity input tray, a duplex unit and an
input option, or more than one input option. If you purchased a multifunction printer (MFP) that scans, copies,
and faxes, you may need additional furniture. For more information, see
www.lexmark.com/multifunctionprinters.
CAUTION—SHOCK HAZARD: If you are accessing the system board or installing optional hardware or memory
devices sometime after setting up the printer, then turn the printer off, and unplug the power cord from the
wall outlet before continuing. If you have any other devices attached to the printer, then turn them off as well,
and unplug any cables going into the printer.

trained personnel to lift it safely.
