The following laser notice labels may be affixed to this printer.
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 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 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.

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 60825-1.
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 60825-1.
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.
Lasermeddelelse
Printeren er godkendt som et Klasse I-laserprodukt, i overenstemmelse med kravene i IEC 60825-1.
Klasse I-laserprodukter betragtes ikke som farlige. Printeren indeholder internt en Klasse IIIB (3b)-laser, der
nominelt er en 5 milliwatt galliumarsenid laser, som arbejder på bølgelængdeområdet 770-795 nanometer.
Lasersystemet og printeren er udformet således, at mennesker aldrig udsættes for en laserstråling over Klasse
I-niveau ved normal drift, brugervedligeholdelse eller obligatoriske servicebetingelser.

During the life of the printer, components are subject to wear based on usage. Printers continuously operating at
or near the maximum duty cycle may require service for replacement of these components to ensure highquality printing and good performance throughout the life of the printer. Replacement is recommended every
60,000 pages for the fuser and 60,000 pages for the ITU. The fuser and ITU replacement should be determined
by checking the last sheet of the Menu Settings Page. Either OK or Replace appears.
To print a Menu Settings page:
1. Press Menu () on the operator panel.
2. Select Reports from the Admin Menu, and press Select ().
3. Select Menu Settings, and press Select ().
