practice or condition that, if not strictly observed, could result in
damage to, or destruction of, equipment.
practice or condition that, if not strictly observed, could result in
injury or loss of life.
Caution:
Danger:
Power Source:
the supply conductors or between either supply conductor and ground. Use only the
specified power cord and connector. For 220 VAC printers, do not apply more than 250
VAC RMS between the supply conductors or between either supply conductor and
ground. Use only the specified power cord and connector. Refer to a qualified service
technician for changes to the cord or connector.
A personal injury hazard exists that may not be apparent. For
example, a panel may cover the hazardous area.
A personal injury hazard exists in the area where you see the sign.
For 110 VAC printers, do not apply more than 130 VAC RMS between
Warning: If the product loses the ground connection, usage of knobs
and controls (and other conductive parts) can cause an
electrical shock.
Phaser 5400 Laser Printer Service Guide iii
Power Supply and Electrical Components:
Before starting any service procedure,
switch off the printer power and unplug the power cord from the wall outlet. If you must
service the printer with power applied, be aware of the potential for electrical shock.
Do not touch any electrical component unless you are instructed to do so by a service
procedure.
S5400-01
Mechanical Components: Manually rotate drive assemblies to inspect sprockets and
gears.
Do not try to manually rotate or manually stop the drive assemblies while any printer motor
is running.
S5400-02
Laser Components
War nin g: This printer generates a laser beam as part of the printing
process. The laser beam is a concentrated narrow beam of
infrared light. The laser beam in this machine is invisible.
Although you cannot see the beam, it can still cause severe
eye damage. Direct eye exposure to the laser beam may
cause eye injury or blindness.
To avoid permanent eye damage, follow these directions:
■ Before starting any service procedure, switch off the printer power and unplug
the power cord from the AC wall outlet.
■ Do not disassemble the Raster Output Scanner Assembly (laser scanner) or any
laser component that displays a Laser Warning Sticker.
■ Use caution when you are working around the Raster Output Scanner Assembly
or when you are performing laser related troubleshooting or repair procedures.
■ Never place a mirror or a reflective tool or object in the laser beam path.
■ Do not disassemble the printer in such a way that the laser beam can exit the
print engine during a print cycle.
iv Phaser 5400 Laser Printer Service Guide
Fuser Components
Warning: This printer uses heat and pressure to fuse the toner image
to a sheet of paper. The Fuser Assembly is very hot. Switch
off printer power and wait at least 30 minutes for the Fuser
to cool before you attempt to service the Fuser Assembly or
adjacent components.
Safety Components:
Make sure covers and panels are in place and that all interlock
switches are all functioning correctly after you have completed a printer service call. If
you bypass, or cheat, an interlock switch during a service call, use extreme caution when
working on or around the printer.
Warning Labels: Throughout the printer, warning labels are displayed on potentially
dangerous components. When you service the printer, check to make certain that all
warning labels are in place.
Most importantly, read and obey all posted warning labels.
Warning: Turning the power off using the On/Off switch does not
de-energize the printer. You must remove the power cord to
disconnect the printer from the main power source. Keep the
power cord accessible for removal in case of an emergency.
Safety Instructions:
Read all installation instructions carefully before you plug the
product into a power source.
Care of Product: Disconnect the power plug by pulling the plug, not the cord.
Disconnect the power plug:
■ If the power cord or plug is frayed or otherwise damaged,
■ If any liquid or foreign material is spilled into the case,
■ If the printer is exposed to any excess moisture,
■ If the printer is dropped or damaged,
■ If you suspect that the product needs servicing or repair, or
■ Whenever you clean the product.
Ground the product: Plug the three-wire power cord (with grounding prong) into
grounded AC outlets only. If necessary, contact a licensed electrician to install a properly
grounded outlet.

Service Safety Summary
For qualified service personnel only: Refer also to the preceding Users Safety
Summary.
Do not service alone: Do not perform internal service or adjustment of this product
unless another person capable of rendering first aid or resuscitation is present.
Use care when servicing with power: Dangerous voltages may exist at several points in
this product. To avoid personal injury, do not touch exposed connections and components
while power is on.
Disconnect power before removing the power supply shield, soldering or replacing
components.
Do not wear jewelry: Remove jewelry prior to servicing. Rings, necklaces and other
metallic objects could come into contact with dangerous voltages and currents.
Power source: This product is intended to operate from a power source that will not apply
more then 250 VAC rms between the supply conductors or between either supply
conductor and ground. A protective ground connection by way of the grounding
conductor in the power cord is essential for safe operation.
This product is certified under IEC 825 as a Class 1 Laser Product.
CLASS 1 LASER PRODUCT
The Phaser 5400 Laser Printer is certified to comply with Laser Product Performance
Standards set by the U.S. Department of Health and Human Services as a Class 1 Laser
Product. This means that this is a class of laser product that does not emit hazardous laser
radiation; this is possible only because the laser beam is totally enclosed during all modes
of customer operation.
The laser and output of the laser scanner unit produces a beam that, if looked into, could
cause eye damage. Service procedures must be followed exactly as written without
change.
When servicing the machine or laser module, follow the procedures specified in the
manual and there will be no hazards from the laser.
Laser (FDA): Any laser label visible to service must be reproduced in the service manual
with location shown or indicated. Safe working procedures and clear warnings concerning
precautions to avoid possible exposure must also be included.
vi Phaser 5400 Laser Printer Service Guide
The Laser contained in the Phaser 5400 Laser Printer meets the following standard: Laser
class 3B, maximum 5 mW, wavelength 780 nm.
The following LASER symbol will be displayed at the start of any procedure where
possible exposure to the laser beam exists.

Federal Communications Commission Compliance
This equipment has been tested and found to comply with the limits set for a Class A
digital device, as stated in Part 15 of the FCC rules. These limits are designed to provide
reasonable protection against harmful interference in a commercial installation. This
equipment generates, uses, and may radiate radio frequency energy. If not installed and
used in accordance with the instructions provided, this equipment may cause disruptive
interference to nearby radio and television communications. Even if the equipment is
installed according to the instructions, there is no guarantee that interference will not
occur in a particular installation. If this equipment does cause disruptive interference to
nearby radio and television reception, switch the equipment off to determine if it is the
true cause of the interference. If the equipment is the cause of the interference, the user
should try to minimize the interference by taking one or more of the following courses of
action:
■ Either re–orient or relocate the radio/television receiving antenna.
■ Increase the separation between the equipment and the radio/television receiver.
■ Connect the equipment to an AC outlet that is not on the same circuit as the
radio/television receiver.
■ If the previous solutions fail to bring results, you should consult either your equipment
dealer or an experienced radio/television technician.
For more information on interference, refer to the Federal Communications Commission’s
booklet “How to Identify and Resolve Radio-TV Interference Problems”. This booklet is
available from the U.S. Government Printing Office, Washington D.C. 20402, Stock No.
