The printer is certified in the U .S. to confo rm to the requir ements of DHHS 21 CFR Subchapter J for Class I (1)
laser product s, 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 int ernally a Class IIIb (3b) laser
that is nominally a 5 milliwatt galli um arsenide laser operati ng in the wavelength region of 770-795 nanometers.
The laser system and printer are designed so there is never an y hum an access to laser radiation above a Class
I level during normal operation, user maintenance, or pr escri bed service condition.
Laser
Der Drucker erfüllt gemäß amtlicher Bestätigu ng 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) 60825-1 gemäß amtlicher Bestäti gung 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 pa ys: cette imprimante répond aux normes IEC 60825-1
relatives aux produits laser de Classe I.
Les produits laser de Classe I sont considérés comm e des produits non dangereux. Cette imprimante est
équipée d’un l aser de Classe IIIb (3b) (arséniure de gall ium d’une puissance nominale de 5 milliwatts) émettant
sur des longueurs d’onde comprises entre 770 et 795 nanomètres. L’imprimante et son sys tème laser sont
conçus pour impossible, dans des conditions normales d’utilisation, d’entr etien par l’utilisateur ou de révision,
