Safety Notes ❖i
Safety Notes
Your printer and the recommended consumable supplies
have been designed and tested to meet strict safety
requirements. Attention to the following notes will ensure
the continued safe operation of your printer.

Note, Caution and Warning Symbols
ii ❖System Administrator Guide
Note, Caution and
Warning Symbols
Throughout this guide, several symbols are used to
emphasize useful, important and critical information.
They are as follows:
When used in a step, the above symbols appear smaller
but are of equal importance.
This symbol indicates particularly useful or helpful
information about your printer.
This symbol indicates a caution against performing any
action that may damage your printer or degrade
performance.
This symbol indicates a warning against
performing any action that may lead to physical
injury.

Electrical Safety
Safety Notes ❖iii
Electrical Safety
• Use the power cord supplied with your printer.
• Do not use a ground adapter plug to connect the
printer to a power source receptacle that lacks a ground
connection terminal.
• Plug the power cord directly into a properly grounded
electrical outlet. Do not use an extension cord. If you
do not know whether an outlet is grounded, ask an
electrician to check the outlet.
• Do not place the printer where people may step on the
power cord.
• Do not place objects on the power cord.
• Do not obstruct the ventilation openings. These
openings are provided to prevent overheating of the
printer.
You may get a severe electrical shock if you do not
connect the grounding conductors correctly.
Do not push objects into slots and openings on the
printer. Making a contact with a voltage point or
shorting out a part could result in fire or electrical
shock.

Electrical Safety
iv ❖System Administrator Guide
• If you notice unusual noises or odors, switch off the
printer power immediately. Disconnect the power cord
from the electrical outlet. Call an authorized service
representative to correct the problem.
• If any of the following conditions occur, switch off the
printer power immediately, disconnect the power cord,
and call an authorized service representative.
— The power cord is damaged or frayed.
— Liquid is spilled into the printer.
— The printer is exposed to water.
— Any part of the printer is damaged.
The power cord is attached to the printer as a plug-in
device at the back of the printer. In the event it is
necessary to remove all electrical power from the printer,
disconnect the power cord from the power receptacle.

Laser Safety
Safety Notes ❖v
Laser Safety
This equipment complies with all applicable safety
standards. With specific regard to laser, the equipment
complies with performance standards for laser products
set by government agencies as a Class 1 laser product. It
does not emit hazardous light; the beam is totally
enclosed during all modes of customer operation and
maintenance.
When performing various operator functions, you may
see laser warning labels. These labels are for the service
mode and are placed on or near panels or shields that
require a tool for removal. These panels are not to be
removed.
The use of controls or adjustments, or the
performance of procedures other than those
specified herein, may result in a hazardous
radiation exposure.

Maintenance Safety
vi ❖System Administrator Guide
Maintenance Safety
• Do not attempt any maintenance procedure that is not
specifically described in the documentation supplied
with your printer.
• Do not use aerosol cleaners. The use of supplies that
are not approved may cause poor performance and
could create a dangerous condition.
• Do not remove the covers or guards that are fastened
with screws unless you are installing optional
equipment. Power should be OFF when performing
these installations. Except for user installable options,
there are no parts that you can maintain or service
behind these covers.
•SeeChapter 4: Maintaining the Printer for maintenance
instructions.

Operational Safety
Safety Notes ❖vii
Operational Safety
Your printer and supplies were designed and tested to
meet strict safety requirements. These include safety
agency examination, approval, and compliance with
established environmental standards.
Your attention to the following safety guidelines will help
to ensure the continued safe operation of your printer.
• Use the material and supplies specifically designed for
your printer. The use of unsuitable materials may result
in poor performance and possibly a hazardous
situation.
• Follow all warnings and instructions marked on, or
supplied with, the printer, options and supplies.
• Place the printer in a dust free area where the
temperature range is 41° F to 95° F (5° C to 35° C) and
the relative humidity is 15% to 85%.
• Place the printer in an area where there is adequate
space for ventilation, operation and servicing. The
recommended minimal spacing is 24 in. (600 mm) in
front of and behind the printer, and 12 in. (300 mm) on
each side of the printer.

Operational Safety
viii ❖System Administrator Guide
• Do not place the printer near a heat source.
• Do not place the printer in direct sunlight.
• Do not place the printer in line with the cold air flow
from an air conditioning system.
• Place the printer on a level, solid surface with adequate
strength for the weight of the machine. The base
printer weight without any packaging materials is
60 pounds (27 kg).
• The printer is heavy. Exercise care in moving or
relocating the printer. Follow the recommended
procedure when moving the printer from one location
to another. See the User Guide.
• Do not put containers of coffee or other liquids onto
the printer.
• Do not block or cover the slots and openings on the
printer. Without adequate ventilation, the printer may
overheat.
Be careful when working in areas identified with a
warning symbol. These areas may be very hot and
could cause personal injury.

Operational Safety
Safety Notes ❖ix
• Frequent operation of the on/off switch is not
recommended.
• Keep hands, hair, jewelry and neckties away from the
exit feed rollers.
• Do not remove a media tray while printing from that
tray or any tray above the media tray in use.
• Do not open the covers while printing.
• Do not switch off the printer power while printing.
• Do not move the printer while printing.

Ozone Safety
x❖System Administrator Guide
Ozone Safety
This printer produces virtually no ozone (< 0.01 ppm)
during normal operation. Providing the proper
environmental parameters, as specified in the Operational
Safety section of these Safety Notes, ensures that
concentration levels meet safe limits.

Using the Control Panel
The printer’s Control Panel (Figure 1.1) serves several
purposes:
• It displays information about the status of the printer
(or the job in process).
• It provides the means for changing printer settings to
control how the printer operates.
• It allows you to print reports and password-protected
pages stored on the optional hard drive.

Using the Control Panel
1-4 ❖System Administrator Guide
The Display The Control Panel's display performs two functions.
• It informs you of printer status conditions, such as
when toner is low, when a paper tray is empty, when a
job is in process, and so on. For example, when you
turn on the printer, the display will show:
This message appears whenever the printer is online
and ready to accept print jobs. The display will also
show:
when processing data, and:
when waiting for more data.
• It presents a hierarchy of menu options and settings to
configure and control the printer.
For example, when you press Menu Up or Menu
Down, the display will show:
(such as System Menu or Job Menu)
See the section “Menu System Overview” (page 1-14) for
information on the Menu system hierarchy.
