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.
Laser
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.
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,

normes IEC 60825-1 relatives aux produits laser de Classe I.
Les produits laser de Classe I sont considérés comme des produits
non dangereux. Cette imprimante est équipée d’un laser de Classe
IIIb (3b) (arséniure de gallium d’une puissance nominale de 5
milliwatts) émettant sur des longueurs d’onde comprises entre 770
et 795 nanomètres. L’imprimante et son système laser sont conçus
pour impossible, dans des conditions normales d’utilisation,
d’entretien par l’utilisateur ou de révision, l’exposition à des
rayonnements laser supérieurs à des rayonnements de Classe I .
Avvertenze sui prodotti laser

classe 1 ed è certificata negli altri Paesi come prodotto laser di
classe 1 conforme ai requisiti della norma CEI 60825-1.
4500
I prodotti laser di classe non sono considerati pericolosi. La
stampante contiene al suo interno un laser di classe IIIb (3b)
all’arseniuro di gallio della potenza di 5mW che opera sulla
lunghezza d’onda compresa tra 770 e 795 nanometri. Il sistema
laser e la stampante sono stati progettati in modo tale che le
persone a contatto con la stampante, durante il normale
funzionamento, le operazioni di servizio o quelle di assistenza
tecnica, non ricevano radiazioni laser superiori al livello della
classe 1.

condiciones expuestas en la norma IEC 60825-1 para productos
láser de Clase I (1).
Los productos láser de Clase I no se consideran peligrosos. La
impresora contiene en su interior un láser de Clase IIIb (3b) de
arseniuro de galio de funcionamiento nominal a 5 milivatios en una
longitud de onda de 770 a 795 nanómetros. El sistema láser y la
impresora están diseñados de forma que ninguna persona pueda
verse 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

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.
4500
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.

1. General information
The Lexmark™ E220/E32x series are letter–quality laser page
monochrome desktop printers designed to fit into space critical
environments and yet not sacrifice speed or ease of use. The
E220/E32x attaches to an IBM Personal Computer or other
computers compatible with the IBM Personal Computer (with 386
processor or higher) and Macintosh Computers via the Universal
Serial Bus (USB) connection.

General information 1-3
4500
There are some apparent differences in the E320/E322 series and
the E220/E321/E323 series. The E220/E321/E323 series has:
• a dark color in most geographies
• two buttons on the operator panel
• a bulge on the right side cover
Internally, the E220/E321/E323 series has:
• a combined engine and RIP card
• a different printhead and interlock switch
• a different fuser
• a different print cartridge
• Nonvolatile random access memory (NVRAM) located on the
operator panel printed circuit board (PCB)
• higher speed pages per minute (ppm).
The E220 is similar to the E321 but has a slower speed.
Other differences are listed in the following table.

Printer operation
Paper is held in a 150 page tray where it is picked by a center–fed D
shape pick roller. The paper follows an L shape path as it moves
through the printer. Images are created with toner on an optical
photoconductor (OPC) drum within the toner cartridge. A transfer
roller then draws the toner off the OPC drum onto the paper. Once
the toner is affixed to the paper by the fuser, the paper exits either
the top or front of the printer.
Printer dimensions and clearance
The following table contains the dimensions for each printer model.
This does not include packaging but does include the print cartridge
that ships with the printer.
