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 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

1. General information
The Lexmark™ C752 is a network-capable color printer that uses electrophotographic technology to deliver high
quality images, presentation graphics, line art, and text. It prints up to 20 pages per minute (ppm) for both fourcolor and monochrome print jobs.
The flexible design supports a variety of printing needs. For example, if you need the printer to match the color
process used in a particular application, you can select RGB or CMYK color corrections. You can also adjust the
printed colors to more closely represent the colors on your computer display.
A variety of connectivity options enable the printer to be used in all types of system environments. You can
attach one internal adapter to support network configurations requiring Ethernet, Token-Ring, LocalTalk, serial,
infrared, or additional parallel ports.
The printer has flexible paper handling. It supports a wide variety of paper sizes, and has a standard
multipurpose feeder that makes it easy to print on envelopes, transparencies, labels, card stock, and nonstandard size paper. You can add optional inputs to the base printer, which can increase the printer paper
capacity to 3100 sheets.
The Lexmark C752 (5060-2XX) laser printer is available in four models:

Performance
Performance speed depends on:
•Interface to the host (USB, serial, parallel, network)
•Host system and application
•Page complexity and content
•Printer options installed or selected
•Available printer memory
•Media size and type
•Resolution
•Printer usage setting
Time to first print

Notes:
a
All first copy times are measured for 600 image quality, simplex printing on letter-size paper. The test job
consists of the character “A” followed by a form feed (single-page job). The first copy time is defined as the
elapsed time from pressing Enter on the keyboard to the page exiting to the output bin. All tests pick paper
from the primary input tray and the page exits into the primary output bin.
b
Standby times may be longer if the toner control senses that toner flow needs to be checked or adjusted.

Available memory options
Optional 64MB, 128MB 256MB and 512MB SDRAM DIMMs are available from Lexmark. The memory options
are 168-pin synchronous DRAM DIMMs (dual in-line memory modules) meeting or exceeding the following
specifications:
•100MHz or greater
•4KB refresh rate
•Unbuffered, non ECC
•x32
•3.3 V
Unpredictable results may occur if an attempt is made to operate the printer with memory other than SDRAM
DIMM memory with the stated specifications.
