cost savings would exceed $1 billion annually and carbon
dioxide emissions would be reduced by 20 million tons.

							Important Safety InstructionsRead all of these instructions before you set up your printer.
Follow all warnings and instructions marked on the printer.
Unplug the printer from the wall outlet before you clean it,
and use a damp cloth for cleaning, not liquid or aerosol
cleaners.
Do not use your printer near water or spill any liquid on it.
Do not place the printer on an unstable cart, stand, table, or
other surface that may allow the printer to fall.
Do not block any slots or openings in the cabinet. These are
provided for the ventilation necessary to ensure reliable
operation and protection from overheating. Placing the
printer on a bed, sofa, rug, or other similar surface may
block the openings. Also, do not place the printer in a
built-in installation unless proper ventilation is provided.
Never place the printer near or over a radiator or heat
register.
Use the type of power source indicated on the label. If you
are not sure of the type of power available, consult your
dealer or local power company.
This printer may be equipped with a plug having a third
(grounding) pin, which fits only into a grounding-type
outlet. This is a safety feature. If you are unable to insert
the plug into the outlet, have an electrician replace your
obsolete outlet, Do not defeat the purpose of the
grounding-type plug.
Do not put your printer where the cord will be walked on.
4 Introduction 
						

							If you use an extension cord, make sure that the total of the
ampere ratings on the products plugged into the extension
cord does not exceed the extension cord’s ampere rating.
Also, make sure that the total of all products plugged into
the wall outlet does not exceed 15 amperes.
Never push objects of any kind into your printer because
they may touch dangerous voltage points or short out parts
that could result in a risk of fire or electric shock.
Except as specifically explained in the user’s manual, do not
attempt to repair the printer yourself. This could expose
you to dangerous voltage points or other risks. Refer all
servicing in those compartments to service personnel.
Unplug the printer from the wall outlet and have it
repaired by a qualified service person under the following
conditions:
When the power cord or plug is damaged or frayed
If liquid has been spilled into it
If it has been exposed to rain or water
If it does not operate normally when the operating
instructions are followed. Adjust only those controls that
are covered by the operating instructions since improper
adjustment of other controls may result in damage and
will often require extensive work by a qualified technician
to restore the printer to normal operation.
If it has been dropped or the cabinet has been damaged
If it exhibits a distinct change in performance, indicating a
need for service

The printout guide is used with the optional cut-sheet feeder. If you
do not have the cut-sheet feeder now, store the printout guide at the
back of the printer cover in case you need it later.Choosing a P/ace for the PrinterWhen selecting a place to set up your printer, choose a
convenient location that provides the following:
A flat, stable surface
Adequate room around the printer to allow easy operation
and maintenance. Make sure it’s close enough to the
computer for the printer cable to reach, and be sure you
can easily unplug the power cord.
Moderate environmental conditions. Select a cool, dry area
and protect your printer from direct sunlight, excessive
heat, moisture, or dust.
Appropriate power source. Make sure you use a grounded
outlet; do not use an adapter plug. Avoid electrical outlets
controlled by timers or wall switches; an interruption in
power can wipe out the information in your computer or
printer memory.

							If you place the printer on a stand, follow these guidelines:
Use a stand that supports at least 9 kg (19 lb).
Never use a stand that tilts the printer. Always keep it level.
Provide enough clearance below the stand and between the
legs of the stand so your continuous paper flows smoothly.
Place cables so they do not interfere with paper feeding;
secure them to a leg of the stand if possible.
