The printer is
Class I (1) laser products, and elsewhere is certified as a Class I laser product conforming to the requirements
of IEC 60825-1.
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 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.

Laserprodukte der Klasse I werden nicht als gefährlich eingestuft. Der Drucker enthält im Inneren einen Laser
der Klasse IIIb (3b), und zwar einen 5-Milliwatt-Gallium-Arsenid-Laser, der im Wellenlängenbereich von 770 bis
795 Nanometern arbeitet. Das Lasersystem und der Drucker sind so konstruiert, dass unter normalen
Betriebsbedingungen, bei der Wartung durch den Benutzer oder bei den vorgeschriebenen
Wartungsbedingungen Menschen keiner Laserstrahlung ausgesetzt sind, die die Werte für Klasse I

Avis relatif à l'utilisation du laser
L'imprimante est certifiée conforme aux exigences de la réglementation des Etats-Unis relative aux produits
laser (DHHS 21 CFR, Chapter I, Subchapter J for Class I (1)). Pour les autres pays, elle est certifiée conforme aux
exigences des normes IEC 60825-1 relatives aux produits laser de classe I.
Les produits laser de Classe I ne sont pas considérés comme dangereux. L'imprimante contient un laser de
classe IIIb (3b), laser arséniure de gallium 7 milliwatts opérant sur une longueur d'onde de l'ordre de 770 à
795 nanomètres. Le système laser ainsi que l'imprimante ont été conçus de manière à ce que personne ne soit
exposé à des rayonnements laser dépassant le niveau de classe I dans le cadre d'un fonctionnement normal,
de l'entretien par l'utilisateur ou de la maintenance.
Avvertenze sui prodotti laser
La stampante è
Sottocapitolo J per i prodotti laser di Classe I (1), mentre in altri paesi è certificata come prodotto laser di Classe
I conforme ai requisiti IEC 60825-1.
I prodotti laser di Classe I non sono considerati pericolosi. La stampante contiene un laser di Classe IIIb (3b),
che è nominalmente un laser ad arseniuro di gallio a 5 milliwatt funzionante a una lunghezza d'onda di 770-795
nanometri. Il sistema laser e la stampante sono stati progettati in modo da impedire l'esposizione a radiazioni
laser superiori al livello previsto dalla Classe I durante le normali operazioni di stampa, manutenzione o
assistenza.

Aviso de láser
Esta impresora se ha certificado en EE. UU. de conformidad con los requisitos de DHHS 21 CFR, capítulo I,
subcapítulo J, para los productos láser de Clase I (1), y en otros países está certificada como un producto láser
de Clase I de acuerdo con los requisitos de IEC 60825-1.
Los productos láser de Clase I no se consideran peligrosos. La impresora contiene un láser interno de Clase
IIIb (3b) que nominalmente es un láser de arseniuro de galio de 5 milivatios que funciona en una longitud de
onda de 770-795 nanómetros. El sistema láser y la impresora se han diseñado para que ningún individuo
acceda nunca a las radiaciones láser por encima del nivel de Clase I durante su uso normal, ni en tareas de
mantenimiento o intervenciones de servicio técnico prescritas.
Aviso sobre laser
A impressora foi certificada nos EUA por estar em conformidade com os requisitos do DHHS 21 CFR, capítulo
I, subcapítulo J, para produtos a laser de Classe I (1) e, nos demais países, foi certificada como produto a laser
de Classe I em conformidade com os requisitos da IEC 60825-1.
Os produtos a laser de Classe I não são considerados perigosos. A impressora contém, internamente, um laser
de Classe IIIb (3b) que é um laser de arsenieto de gálio de 5 miliwatts operando no comprimento de onda de
770-795 nanômetros. O sistema do laser e a impressora foram projetados para que jamais haja acesso humano
à radiação do laser acima do nível da Classe I durante a operação normal ou a manutenção pelo usuário ou

Laserinformatie
Deze printer is in de Verenigde Staten gecertificeerd als een product dat voldoet aan de vereisten van DHHS
21 CFR, hoofdstuk 1, paragraaf J voor laserproducten van klasse I (1). Elders is de printer gecertificeerd als een
laserproduct van klasse I dat voldoet aan de vereisten van IEC 60825-1.
Laserproducten van klasse I worden geacht geen gevaar op te leveren. De printer bevat intern een laser van
klasse IIIb (3b), een galliumarsenide laser met een nominaal vermogen van 5 milliwatt en een golflengtebereik
van 770-795 nanometer. Het lasersysteem en de printer zijn zodanig ontworpen dat gebruikers nooit blootstaan
aan laserstraling die hoger is dan het toegestane niveau voor klasse I-apparaten, tijdens normaal gebruik,
onderhoudswerkzaamheden door de gebruiker of voorgeschreven servicewerkzaamheden.
Lasererklæring
Denne printer er certificeret i USA i henhold til kravene i DHHS 21 CFR, afsnit I, underafsnit J, for Klasse Ilaserprodukter (1) og certificeret andetsteds som et Klasse I-laserprodukt i henhold til kravene i IEC 60825-1.
Klasse I-laserprodukter anses ikke for at være farlige. Printeren indeholder internt en klasse IIIb (3b)-laser, der
nominelt er en 5 milliwatt galliumarsenid-laser, som fungerer i bølgelængdeområdet 770-795 nanometer.
Lasersystemet og printeren er udviklet på en sådan måde, at der ikke er en direkte laserstråling, der overskrider
Klasse I-niveauet under normal brug, brugers vedligeholdelse eller de foreskrevne servicebetingelser.
