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.

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

xi Service Manual

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

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

Notices and Safety Information xii

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
