CAUTION—SHOCK HAZARD: To avoid the risk of electric shock when cleaning the exterior of the printer, unplug
the power cord from the wall outlet and disconnect all cables from the printer before proceeding.
CAUTION—SHOCK HAZARD: To avoid the risk of electric shock when cleaning the interior of the printer, unplug
the power cord from the wall outlet and disconnect all cables from the printer before proceeding.
CAUTION—SHOCK HAZARD: Do not use the fax feature during a lightning storm. Do not set up this product or
make any electrical or cabling connections, such as the fax feature, power cord, or telephone, during a lightning
storm.
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.
CAUTION—POTENTIAL INJURY: To reduce the risk of equipment instability, load each paper drawer or tray
separately. Keep all other drawers or trays closed until needed.
SAVE THESE INSTRUCTIONS.
