Laser notice

The printer is certified in the U.S. to conform to the requirements of
DHHS 21 CFR Subchapter J for Class I (1) laser products, and
elsewhere is certified as a Class I laser product conforming to the
requirements of IEC 60825.

Class I laser products are not considered to be hazardous. The
printer contains internally a Class IIIb (3b) laser that is nominally a 5
milliwatt gallium arsenide laser operating in the wavelength region of
770-795 nanometers. The laser system and printer are designed so
there is never any human access to laser radiation above a Class I
level during normal operation, user maintenance, or prescribed
service condition.

Laser

Der Drucker erfüllt gemäß amtlicher Bestätigung der USA die
Anforderungen der Bestimmung DHHS (Department of Health and
Human Services) 21 CFR Teil J für Laserprodukte der Klasse I (1).
In anderen Ländern gilt der Drucker als Laserprodukt der Klasse I,
der die Anforderungen der IEC (International Electrotechnical
Commission) 60825 gemäß amtlicher Bestätigung erfüllt.

Laserprodukte der Klasse I gelten als unschädlich. Im Inneren des
Druckers befindet sich ein Laser der Klasse IIIb (3b), bei dem es
sich um einen Galliumarsenlaser mit 5 Milliwatt handelt, der Wellen
der Länge 770-795 Nanometer ausstrahlt. Das Lasersystem und der
Drucker sind so konzipiert, daß im Normalbetrieb, bei der Wartung
durch den Benutzer oder bei ordnungsgemäßer Wartung durch den
Kundendienst Laserbestrahlung, die die Klasse I übersteigen würde,
Menschen keinesfalls erreicht.

3. Repair Information

Handling ESD-Sensitive P arts

Many electronic products use parts that are known to be sensitive to
electrostatic discharge (ESD). To prevent damage to ESD-sensitive
parts, follow the instructions below in addition to all the usual
precautions, such as turning off power before removing logic boards:

• Keep the ESD-sensitive part in its ori gi nal shipping container

(a special “ESD bag”) until you are ready to install the part into
the printer.

• Make the least-possible movements with your body to prevent

an increase of static electricity from clothing fibers, carpets, and
furniture.

• Secure the ESD wrist strap around your wrist and connect the

wrist band to the engine ground point. This discharges any
static electricity, in your body, to the printer.

• Hold the ESD-sensitive part by its edge connector shroud

(cover); do not touch the pins. If you are removing a pluggable
module, use the correct tool.

• Do not place the ESD-sensitive part on the printer cover or on a

metal table, as electrical grounding may occur, which increases
the risk of damage due to the discharge path your body could
establish through the ESD-sensitive part. (Large metal objects
can be discharge paths without being grounded.)

• When laying the ESD-sensitive part down, always return it to

the ESD-sensitive bag.

• If possible, keep all ESD-sensitive parts in a grounded metal

cabinet (case).

• Take care working with ESD-sensitive parts when cold weather

heating is used, as low humidity increases static electricity.
