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.

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

• The Infoprint 1222 Network printer, with 32MB of memory
standard, an integrated Ethernet adapter, a parallel port, and a
USB port.
The purpose of this chapter is to provide an overview of the

repair the failure. See “Diagnostic Information” on page 2-1, for
the location of each section. See the “Repair Information” on
page 4-1 to help identify parts. After completing the repair, perform
tests as needed to verify the repair.
