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.

1. General information

The Le xm ark™ C76x is a network-capable color printer that uses electrophotogr aphic technology to deliver high
quality image s, presentation graphics, line art, and text. It prints up to 25 pages per minute (ppm) for both four­color and monochrome pri nt 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.

The Lexmark C76x (5060-4xx) laser printer is av ailable in four models:

Lexmark C760 5060-401 Non-netw ork

Service checks

100 ITU Error

A 100 ITU error indicates that the printer did not detect the ITU bel t home sensor. Before proceeding with this
service check make sure that the Second Transfer Roll is correctly installed. After you reinstall the Second
Transfer Roll, check to see if a 100 ITU error is still displayed. If a 100 ITU er ror is still being displayed, continue
with this check.

The ITU has an optical sensor that watches f or a piece of reflective tape on the inside of the image bel t. This
tape is read every revolution of the belt. If a signal is not received from the belt sensor within a certain time
period, the printer posts an error due to the loss of signal. There are several causes f or the loss of signal. First,
the belt has t racked too far to the front or rear of the printer. In this case, the belt is still turning, but the r e fl ective
tape is no longer passing within view of the belt sensor. Thi s is considered a belt trac king error and is initial ly
posted as a 104 ITU Erro r . The other caus es of a sig nal loss could be a bel t stall, meaning th e belt i s not turning,
or a true si gnal loss, whi ch would be due to a bad sensor, broken cable, loose connecti on, or bad system board.
These other causes post as a 100 ITU Error.

To assist the printer in determining what is the cause of a signal loss, there is a buffer that records the belt
position f or the last 50 revolutions. If t he printer loses the belt signal, it refers to the buffer. If the buffer shows
significant mistracking before signal loss, it will post a 104 ITU Error. If the buffer shows that the belt has been
tracki ng in the center befo re si gnal loss, it posts a 100 ITU Error. Due to memory restrictions, the buff er is not
sav ed duri ng PO R. This means, if a printer posts a 104 ITU Error, so the belt is tracked off, and the customer or
servicer turns off the printer t o clear t he error, when the printer starts up, it will stil l not see t he belt si gnal and will
now post a 100 ITU Error because the buffer is empt y. When servicing a printer for a 100 ITU Error, it is
important to view the error log. See “Display Log” on page 3-35. The error log can only be displayed at this
point. Do not try to print the log. Look for past occurrences of 100 ITU Errors preceded by a 104 ITU Error.
