Electrostatic Discharge Precautions, Regulatory
Introduction
Xerox Internal Use Only - Revised, 3rd Revision
Electrostatic Discharge Precautions
Some semiconductor components, and the respective sub-assemblies that contain them, are
vulnerable to damage by Electrostatic Discharge (ESD). These components include Integrated
Circuits (ICs), Large-Scale Integrated circuits (LSIs), field-effect transistors, and other semi
-
conductor chip components. The following techniques will reduce the occurrence of compo-
nent damage caused by static electricity.
Be sure the power is off to the chassis or the circuit board, and observe all other safety precau-
tions.
• Immediately before handling any semiconductor components assemblies, drain the elec-
trostatic charge from your body. This can be accomplished by touching an earth ground
source or by wearing a wrist strap device connected to an earth ground source. Wearing
a wrist strap will also prevent accumulation of additional bodily static charges. Be sure to
remove the wrist strap before applying power to the unit under test to avoid potential
shock.
• After removing a static sensitive assembly from its anti-static bag, place it on a grounded
conductive surface. If the anti-static bag is conductive, you may ground the bag and use it
as a conductive surface.
• Do not use freon-propelled chemicals. These can generate electrical charges sufficient to
damage some devices.
• Do not remove a replacement component or electrical sub-assembly from its protective
package until you are ready to install it.
• Immediately before removing the protective material from the leads of a replacement
device, touch the protective material to the chassis or circuit assembly into which the
device will be installed.
• Minimize body motions when handling unpacked replacement devices. Motion such as
your clothes brushing together, or lifting a foot from a carpeted floor can generate enough
static electricity to damage an electro-statically sensitive device.
• Handle IC’s and Erasable Programmable Read-Only Memories (EPROM’s) carefully to
avoid bending the pins.
• Pay attention to the direction of parts when mounting or inserting them on the Printed Cir-
cuit Boards (PCB’s).
Regulatory Requirements
Xerox has tested this printer to electromagnetic emission and immunity standards. These stan-
dards are designed to mitigate interference caused or received by this printer in a typical office
environment.
United States (FCC Regulations)
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protec
-
tion against harmful interference when the equipment is operated in a commercial environ-
ment. This equipment generates, uses, and can radiate radio frequency energy. If it is not
installed and used in accordance with these instructions, it may cause harmful interference to
radio communications. Operation of this equipment in a residential area is likely to cause harm
-
ful interference in which case the user will be required to correct the interference at his/her own
expense.
If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the receiver.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver
is connected.
• Consult the dealer or an experienced radio/television technician for help.
Any changes or modifications not expressly approved by Xerox could void the user's authority
to operate the equipment. To ensure compliance with Part 15 of the FCC rules, use shielded
interface cables.
Canada (Regulations)
This Class A digital apparatus complies with Canadian ICES-003.
Cet appareil numérique de la classe A est conforme
à la norme NMB-003 du Canada.
European Union
This product, if used properly in accordance with the user's instructions, is neither dangerous
for the consumer nor for the environment.
To ensure compliance with European Union regulations, use shielded interface cables.
A signed copy of the Declaration of Conformity for this product can be obtained from Xerox.
The CE mark applied to this product symbolizes Xerox’s decla-
ration of conformity with the following applicable Directives of
the European Union as of the dates indicated:
• December 12, 2006: Low Voltage Directive 2006/95/EC
• December 15, 2004: Electromagnetic Compatibility Directive 2004/108/EC
