Notices and Safety Information
References in this publication to products, programs, or services do
not imply that the manufacturer intends to make these available in all
countries in which it operates. Any reference to a product, program,
or service is not intended to state or imply that only that product, pro-
gram, or service may be used. Any functionally equivalent product,
program, or service that does not infringe any existing intellectual
property rights may be used instead. Evaluation and verification of
operation in conjunction with other products, programs, or services,
except those expressly designated by the manufacturer, are the
user’s responsibility.
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 else-
where is certified as a Class I laser product conforming to the
requirements of IEC 825.
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) 825 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.
Avis relatif à l’utilisation de laser
Pour les Etats-Unis : cette imprimante est certifiée conforme aux
provisions DHHS 21 CFR alinéa J concernant les produits laser de
Classe I (1). Pour les autres pays : cette imprimante répond aux
normes IEC 825 relatives aux produits laser de Classe I.
Les produits laser de Classe I sont considérés comme des produits
non dangereux. Cette imprimante est équipée d’un laser de Classe
IIIb (3b) (arséniure de gallium d’une puissance nominale de 5
milliwatts) émettant sur des longueurs d’onde comprises entre 770
et 795 nanomètres. L’imprimante et son système laser sont conçus
pour impossible, dans des conditions normales d’utilisation,
d’entretien par l’utilisateur ou de révision, l’exposition à des
rayonnements laser supérieurs à des rayonnements de Classe I .

Avvertenze sui prodotti laser
Questa stampante è certificata negli Stati Uniti per essere conforme
ai requisiti del DHHS 21 CFR Sottocapitolo J per i prodotti laser di
classe 1 ed è certificata negli altri Paesi come prodotto laser di
classe 1 conforme ai requisiti della norma CEI 825.
I prodotti laser di classe non sono considerati pericolosi. La
stampante contiene al suo interno un laser di classe IIIb (3b)
all’arseniuro di gallio della potenza di 5mW che opera sulla
lunghezza d’onda compresa tra 770 e 795 nanometri. Il sistema
laser e la stampante sono stati progettati in modo tale che le
persone a contatto con la stampante, durante il normale
funzionamento, le operazioni di servizio o quelle di assistenza
tecnica, non ricevano radiazioni laser superiori al livello della classe
1.
Avisos sobre el láser
Se certifica que, en los EE.UU., esta impresora cumple los
requisitos para los productos láser de Clase I (1) establecidos en el
subcapítulo J de la norma CFR 21 del DHHS (Departamento de
Sanidad y Servicios) y, en los demás países, reúne todas las
condiciones expuestas en la norma IEC 825 para productos láser de
Clase I (1).
Los productos láser de Clase I no se consideran peligrosos. La
impresora contiene en su interior un láser de Clase IIIb (3b) de
arseniuro de galio de funcionamiento nominal a 5 milivatios en una
longitud de onda de 770 a 795 nanómetros. El sistema láser y la
impresora están diseñados de forma que ninguna persona pueda
verse afectada por ningún tipo de radiación láser superior al nivel de
la Clase I durante su uso normal, el mantenimiento realizado por el
usuario o cualquier otra situación de servicio técnico.

Declaração sobre Laser
A impressora está certificada nos E.U.A. em conformidade com os
requisitos da regulamentação DHHS 21 CFR Subcapítulo J para a
Classe I (1) de produtos laser. Em outros locais, está certificada
como um produto laser da Classe I, em conformidade com os
requisitos da norma IEC 825.
Os produtos laser da Classe I não são considerados perigosos.
Internamente, a impressora contém um produto laser da Classe IIIb
(3b), designado laser de arseneto de potássio, de 5 milliwatts
,operando numa faixa de comprimento de onda entre 770 e 795
nanómetros. O sistema e a impressora laser foram concebidos de
forma a nunca existir qualquer possiblidade de acesso humano a
radiação laser superior a um nível de Classe I durante a operação
normal, a manutenção feita pelo utilizador ou condições de
assistência prescritas.
Laserinformatie
De printer voldoet aan de eisen die gesteld worden aan een
laserprodukt van klasse I. Voor de Verenigde Staten zijn deze eisen
vastgelegd in DHHS 21 CFR Subchapter J, voor andere landen in
IEC 825.
Laserprodukten van klasse I worden niet als ongevaarlijk
aangemerkt. De printer is voorzien van een laser van klasse IIIb
(3b), dat wil zeggen een gallium arsenide-laser van 5 milliwatt met
een golflengte van 770-795 nanometer. Het lasergedeelte en de
printer zijn zo ontworpen dat bij normaal gebruik, bij onderhoud of
reparatie conform de voorschriften, nooit blootstelling mogelijk is
aan laserstraling boven een niveau zoals voorgeschreven is voor
klasse 1.
