Laser no tice
The printer is certified in the U .S. to conform to the requirements 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 req uir em ents of IEC
60825-1.
Class I laser products are not considered to be hazardous. The printer con tai ns internally a Class IIIb (3b) laser
that is nominally a 10 milliwatt diode laser using an aluminum galliu m indium phosphide structure laser
operating in the wavelength region of 645-670 nanometers. The l aser system and printer are des igned so there
is never any human access to l aser radiation above a Class I level during normal oper ation, user maintenance,
or prescribed service condi tion.

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) 60825-1 gemäß amtlicher Bestätigung erfüllt.
5062
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 Klasse I überstei gen würde, Menschen keinesfalls erreicht.
Avis relatif à l’utilisation de laser
