Connect the power cord to a properly grounded electrical outlet that is near the product and easily accessible.
Do not place or use this product near water or wet locations.
CAUTION—POTENTIAL INJURY: This product uses a laser. Use of controls or adjustments or performance of
procedures other than those specified herein may result in hazardous radiation exposure.
This product uses a printing process that heats the print media, and the heat may cause the media to release emissions.
You must understand the section in your operating instructions that discusses the guidelines for selecting print media
to avoid the possibility of harmful emissions.
CAUTION—POTENTIAL INJURY: The lithium battery in this product is not intended to be replaced. There is a
danger of explosion if a lithium battery is incorrectly replaced. Do not recharge, disassemble, or incinerate a
lithium battery. Discard used lithium batteries according to the manufacturer's instructions and local
regulations.
CAUTION—HOT SURFACE: The inside of the printer might be hot. To reduce the risk of injury from a hot
component, allow the surface to cool before touching.
CAUTION—POTENTIAL INJURY: The printer weight is greater than 18 kg (40 lb) and requires two or more
trained personnel to lift it safely.
CAUTION—POTENTIAL INJURY: Before moving the printer, follow these guidelines to avoid personal injury or
printer damage:
• Turn the printer off using the power switch, and then unplug the power cord from the wall outlet.
• Disconnect all cords and cables from the printer before moving it.
• Lift the printer off the optional drawer, and set it aside instead of trying to lift the drawer and printer at the same
time.
Note: Use the handholds located on both sides of the printer to lift it off the optional drawer.
Use only the power cord provided with this product or the manufacturer's authorized replacement.
CAUTION—POTENTIAL INJURY: To reduce risk of fire, use only the telecommunications (RJ‑11) cord provided
with this product or a UL Listed 26 AWG or larger replacement when connecting this product to the public
switched telephone network.
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—SHOCK HAZARD: Make sure that all external connections (such as Ethernet and telephone system
connections) are properly installed in their marked plug-in ports.
This product is designed, tested, and approved to meet strict global safety standards with the use of specific
manufacturer's components. The safety features of some parts may not always be obvious. The manufacturer is not
responsible for the use of other replacement parts.
CAUTION—POTENTIAL INJURY: Do not cut, twist, bind, crush, or place heavy objects on the power cord. Do not
subject the power cord to abrasion or stress. Do not pinch the power cord between objects such as furniture
and walls. If any of these things happen, a risk of fire or electrical shock results. Inspect the power cord regularly
for signs of such problems. Remove the power cord from the electrical outlet before inspecting it.
Refer service or repairs, other than those described in the user documentation, to a professional service person.
Safety information12
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 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—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.
