Laser no tice
The printer is certified in the U .S. to confo rm to the requir ements 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 requirements of IEC
60825-1.
Class I laser products are not considered to be hazardous. The printer contains int ernally a Class IIIb (3b) laser
that is nominally a 5 milliwatt galli um arsenide laser operati ng in the wavelength region of 770-795 nanometers.
The laser system and printer are designed so there is never an y hum an access to laser radiation above a Class
I level during normal operation, user maintenance, or pr escri bed service condition.

Der Drucker erfüllt gemäß amtlicher Bestätigu ng 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 Bestäti gung 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,

The Lexmark™ C77x, C78x (5061-xxx) is a network-capable color printer that uses electrophotographic
technology to deliver high-quality images, presentation graphics, line art, and text. It prints both four-color 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 appli cati on, you can sel ect RGB or CMYK color cor rections . You can also adjust the
printed colors to more closely represent the colors on your comput er di splay.
A variety of con nectivity options enable the printer to be used in all types of system enviro nm ents. You can
attach one internal adapter to support network configurati ons 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 siz e paper. You can add optional i nputs to the base printer, which can increase the printer paper
capacity to 3100 sheets.

Time to first print
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 cop y ti m e is defined as the
elapsed ti me from pressing Enter on the ke yboard to the page exiting to the output bin. All tests pi ck paper from
the primary input tra y and the page exits into the primary output bin.
Standby times may be longer if the toner control senses that toner flow needs to be checked or adjusted.

Ava ilable memory options
Optional 128MB, 256M B and 512M B SDRAM DIMMs are available from Lexmark. The memory options are
168-pin synchronous DRAM DIMMs (dual in-line memory modules) mee ti ng or exceeding the f ollowing
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.
Flash Memory Options available are 32MB and 64M B.
