WARNING:
This equipment has been tested and found to
comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable
protection against harmful interference when the
equipment is operated in a commercial
environment. This equipment generates, uses,
and can radiate radio frequency energy and, if
not installed and used in accordance with the
instruction manual, may cause harmful
interference to radio communications. Operation
of this equipment in a residential area is likely to
cause harmful interference in which case the user
will be required to correct the interference at his
own expense.
CAUTION
Use of control or adjustments or perfomance of
procedures other than those specified herein may
result in hazardous radiation exposure.
Shielded interconnect cables must be employed
with this equipment to ensure compliance with
the pertinent RF emission limits governing this
device.
Operator Safety
This equipment is considered a CDRH Class 1
laser device, safe for office/EDP use. The
machine contains a 5-milliwatt, 760 to 800
nanometer wavelength, GaAIAs laser diode.
Direct (or indirect reflected) eye contact with the
laser beam may cause serious eye damage.
Safety precautions and interlock mechanisms
have been designed to prevent any possible laser
beam exposure to the operator.
Laser Safety
The Center for Devices and Radiological Health
(CDRH) prohibits the repair of laser-based optical
units in the field. The optical housing unit can
only be repaired in a factory or at a location with
the requisite equipment. The laser subsystem is
replaceable in the field by a qualified Customer
Engineer. The laser chassis in not repairable in
the field. Customer engineers are therefore
directed to return all chassis and laser
subsystems to the factory or service depot when
replacement of the optical subsystem is required.
In accordance with ISO 7001, this machine uses
the following symbols for the main switch:
smeans POWER ON
tmeans POWER OFF
CAUTION
Deliver to collection point for waste products. Do
not be disposed of via domestic refuse collection.
WARNING
This symbol is attached to some
components to alert the user not to
touch them because they may be very
hot.
This symbol is intended to alert the user
to the presence of important operating
and maintenance (servicing) instructions
in the literature accompanying the
machine.
Notice about the Telephone Consumer
Protection Act (Valid in USA only).
The Telephone Consumer Protection Act of 1991
among other things makes it unlawful for any
person to send any message via a telephone fax
machine unless such message clearly contains in
a margin at the top or bottom of each transmitted
page or on the first page of the transmission, the
date and time it is sent and an identification of
the business, other entity, or other individual
sending the message and the telephone number
of the sending machine or such business, other
entity or individual. This information is transmitted
with your document by the TTI (Transmit
Terminal Identification) feature.
The telephone number provided may not be a
900 number or any other number for which
charges exceed local or long distance
transmission charges.
In order for you to meet the requirement, your
machine must be programmed by following the
instructions in the accompanying Operation
Manual. In particular, please refer to Appendix
F:Installation the machine. Also refer to the TTI
(Transmit Terminal Identification) programming
procedure to enter the business identification and
telephone number of the terminal or business. Do
not forget to set the date and time.
Thank you.

GLOSSARY 308

Thank you for purchasing this product.This multi-function office machine offers a
wide range of fax, printer, and convenience features (Some of these features are
optional).
WHAT DOES A FAX MACHINE DO?
When you write a letter, you normally seal it in an envelope, attach a stamp, and post it in the
nearest mail box. Then, in a few days, depending on the postal service, the letter will arrive at its
destination. However, you may not be aware of its arrival until you get a return letter.
A fax machine speeds up this process.After you have written your letter, place it face down in your
fax machine’s document feeder, dial the destination’s fax number, then press the Start key.
The fax machine scans your letter, and converts it into a series of black and white dots (the number
of dots that there are across and down the page depends on the resolution that you selected; refer
to the specifications section of this manual for details).This series of dots is transformed into an
electrical signal and sent out over the telephone line to the destination fax machine.
The receiving fax machine reconstructs your letter from the incoming signal, and prints it.
If you are worried about whether the message arrived at the destination, you can check a report
called the Journal. When you print this report, you will see the results of the most recent fax
communications made by your machine.
You can use your fax machine to send and receive many types of documents, even photographs.
TELEPHONE LINE PROBLEMS AFFECT FAX
COMMUNICATION
Quick and accurate transmission of fax messages depends
on the condition of the telephone line.If the line condition is
very good, this machine will transmit a letter-size page in
about 6 seconds.However, if the line is noisy, the speed
may be reduced significantly, and the data may be
damaged.
The symptoms of data loss caused by a noisy telephone
line are seen on the printouts of received messages.An
example is shown opposite.Note that lines are missing
from the page at the indicated locations.ECM (Error
Correction Mode) is an effective countermeasure against
this type of error; you have the choice of having the ECM
feature switched on or off. It is switched on before the
machine leaves the factory. (Refer to page 96 for more
information about ECM).
The line condition is affected by the weather; thunderstorms can cause electrical noise on
telephone lines.
In addition, the quality and condition of switching equipment used by your phone company can
affect fax communication.

If you see something like "# x 3", this means that you have to press the #key 3
times.
On the operation panel, there are four arrow keys (up, down, left,
right). This is the scroll key.It is often used in the operating
procedures to gain access to various features. For example, if you
see Vin the manual, you are being asked to press the
right-pointing arrow (V) on the scroll key.
Displays
Messages seen on the display are shown in a larger box, normally on the right
hand side of the page, directly opposite the step that brought it up on the screen.
After following a step in a procedure, check the display to see if it corresponds to
the one in the manual. This may help you to check whether you are following the
procedure successfully. The following examples show three common types of
display.
Example A:The keys that can be pressed
are shown on the screen in small boxes. In
this example, you can press the Yes, No, or
Clear keys or down arrow (T) on the scroll
key.
Example B: The choices of settings for a
feature are shown on the screen.The
current setting is indicated ( It is set ON).If
you press the Wor Von the scroll key, the
setting will be changed to OFF.
Example C:The ABC in the bottom right of
the display indicates letters (using the Quick
Dial Keys) or numbers (using the ten-key
pad on the operation panel) can be entered.
