Electrostatic Discharge (Esd) Precautions; Generic Warnings With Figs - Xerox Phaser 7760 Service Manual

Servicing Fuser Components
This printer uses heat to fuse the toner image to the media. The Fuser is VERY HOT.
Turn the printer power OFF and wait at least 5 minutes for the Fuser to cool before
attempting to service the Fuser or adjacent components.

Electrostatic Discharge (ESD) 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 semicon-
ductor chip components. The following techniques will reduce the occurrence of component
damage caused by static electricity.
Be sure the power is off to the chassis or 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 EPROM's carefully to avoid bending pins.
• Pay attention to the direction of parts when mounting or inserting them on Printed Circuit
Boards (PCB's).

Generic Warnings with FIGS

General Usage
Use only Xerox materials and components. This product is safety certified using Xerox
materials and components. The use of non Xerox materials and components may invali-
date the safety certificate.
DANGER : N'utilisez que des matières premières et des composants Xerox. La sécurité
du produit est assurée dans le cadre de son utilisation avec des matières premières et
des composants Xerox. L'utilisation de matières premières et de composants autres
que ceux de Xerox risque d'invalider le certificat de sécurité.
AVVERTENZA: Utilizzare solo materiali e componenti Xerox per avvalersi della certifi-
cazione di protezione. L'utilizzo di materiali e componenti non Xerox può rendere nulla
la certificazione di protezione.
VORSICHT: Verwenden Sie nur Materialien und Komponenten von Xerox. Dieses
Produkt besitzt die Sicherheitszertifizierung bei Verwendung von Xerox-Materialien und
-Komponenten. Die Verwendung von Materialien und Komponenten anderer Hersteller
setzt möglicherweise das Sicherheitszertifikat außer Kraft.
AVISO: Utilice solo los materiales y componentes Xerox. Este producto dispone de un
certificado de seguridad si se utilizan los materiales y componentes Xerox. Este certifi-
cado de seguridad no será válido si se utilizan materiales y componentes que no sean
de Xerox.
A warning is used whenever an operating or maintenance procedure, practice, condi-
tion or statement, if not strictly observed, could result in personal injury.
DANGER: Une note Danger est utilisée chaque fois qu'une procédure d'utilisation ou de
maintenance peut être cause de blessure si elle n'est pas strictement respectée.
AVVERTENZA: Un segnale di avvertenza è utilizzato ogni volta che una procedura oper-
ativa o di manutenzione, una pratica, una condizione o un'istruzione, se non stretta-
mente osservata, potrebbe causare lesioni personali.
VORSICHT: Weist darauf hin, dass ein Abweichen von den angeführten Arbeits- und
Wartungsanweisungen gesundheitliche Schäden, möglicherweise sogar schwere Ver-
letzungen zur Folge haben kann.
AVISO:Un aviso se utiliza siempre que un procedimiento de operación o mantenimiento,
práctica o condición puede causar daños personales si no se respetan estrictamente.
