Setting Up the Projector
Follow the instructions in these sections to set up your projector for use.

Projector Connections
Installing Batteries in the Remote Control
Opening the Lens Cover

Projector Placement
You can place the projector on almost any flat surface to project an image.
You can also install the projector in a ceiling mount if you want to use it in a fixed location.
Keep these considerations in mind as you select a projector location:
• Place the projector on a sturdy, level surface or install it using a compatible mount.
• Leave plenty of space around and under the projector for ventilation, and do not place it on top of or
next to anything that could block the vents.
• Position the projector within reach of a grounded electrical outlet or extension cord.

Projector Setup and Installation Options
You can set up or install your projector in the following ways:
Front

Rear

Front Ceiling

Rear Ceiling

Wherever you set up the projector, make sure to position it squarely in front of the center of the screen,
not at an angle, if possible.
If you project from the ceiling or from the rear, be sure to select the correct Projection option in the
projector's menu system.

Projection Distance
The distance at which you place the projector from the screen determines the approximate size of the
image. The image size increases the farther the projector is from the screen, but can vary depending on
the zoom factor, aspect ratio, and other settings.
Use the tables here to determine approximately how far to place the projector from the screen based on
the size of the projected image. (Conversion figures may have been rounded up or down.) You can also
use the projector Throw Distance Calculator at epson.com/support (U.S.) or epson.ca/support (Canada).

Saving a User's Logo Image to Display
You can transfer an image to the projector and then display it whenever the projector turns on. You can
also display the image when the projector is not receiving an input signal or when you temporarily stop
projection (using the A/V Mute feature). This transferred image is called the User's Logo screen.
The image you select as the User's Logo can be a photo, graphic, or company logo, which is useful in
identifying the projector's owner to help deter theft. You can prevent changes to the User's Logo by
setting up password protection for it.

Note: In some cases the brightness and color tone from different projectors may not match completely
even after color correction. If the brightness and color tone differences become more noticeable over
time, repeat the adjustments.
You can also match the colors displayed by any projectors you plan to use near each other.

Projector Maintenance
Your projector needs little maintenance to keep working at its best.
You may need to clean the lens periodically, and clean the air filter and air vents to prevent the projector
from overheating due to blocked ventilation.
The only parts you should replace are the lamp, air filter, and remote control batteries. If any other part
needs replacing, contact Epson or an authorized Epson servicer.
Warning: Before cleaning any part of the projector, turn it off and unplug the power cord. Never open
any cover on the projector, except as specifically explained in this manual. Dangerous electrical voltages
in the projector can injure you severely.
Warning: Do not try to service this product yourself, except as specifically explained in this manual.
Refer all other servicing to qualified servicers.

Cleaning the Lens
Clean the projector's lens periodically, or whenever you notice dust or smudges on the surface.
• To remove dust or smudges, gently wipe the lens with lens-cleaning paper.

136

• To remove stubborn smudges, moisten a soft, lint-free cloth with lens cleaner and gently wipe the
lens. Do not spray any liquid directly on the lens.
Warning: Do not use a lens cleaner that contains flammable gas. The high heat generated by the
projector lamp may cause a fire.
Caution: Do not use glass cleaner or any harsh materials to clean the lens and do not subject the lens
to any impacts; you may damage it. Do not use canned air, or the gases may leave a residue. Avoid
touching the lens with your bare hands to prevent fingerprints on or damage to the lens surface.
Parent topic: Projector Maintenance

Cleaning the Projector Case
Before cleaning the projector case, turn off the projector and unplug the power cord.
• To remove dust or dirt, use a soft, dry, lint-free cloth.
• To remove stubborn dirt, use a soft cloth moistened with water and mild soap. Do not spray liquid
directly on the projector.
Caution: Do not use wax, alcohol, benzine, paint thinner, or other chemicals to clean the projector
case. These can damage the case. Do not use canned air, or the gases may leave a residue.
Parent topic: Projector Maintenance

Air Filter and Vent Maintenance
Regular filter maintenance is important to maintaining your projector. Your Epson projector is designed
with an easily accessible, user-replaceable filter to protect your projector and make regular maintenance
simple. Filter maintenance intervals will depend on the environment.
If regular maintenance is not performed, your Epson projector will notify you when the temperature
inside the projector has reached a high level. Do not wait until this warning appears to maintain your
projector filter as prolonged exposure to high temperatures may reduce the life of your projector or lamp.
Damage due to the failure to properly maintain the projector or its filter may not be covered by the
projector or lamp Limited Warranties.

lamp.
Parent topic: Notices

178

Important Safety Instructions
Follow these safety instructions when setting up and using the projector:
• Do not look into the lens when the projector is on. The bright light can damage your eyes. Avoid
standing in front of the projector so the bright light does not shine into your eyes.
• Do not place the projector on an unstable cart, stand, or table.
• Do not operate the projector on its side, or while tilted to one side. Do not tilt the projector more than
30° forward or back.
• If the projector is mounted on a ceiling or wall, it should be installed by qualified technicians using
mounting hardware designed for use with this projector.
• When installing or adjusting a ceiling or wall mount, do not use adhesives to prevent the screws from
loosening and do not use oils or lubricants. This may cause the projector case to crack and the
projector to fall from its ceiling mount. This could cause serious injury to anyone under the mount and
could damage the projector.
• Do not use the projector near water, sources of heat, high-voltage electrical wires, or sources of
magnetic fields.
• Use the type of power source indicated on the projector. Use of a different power source may result in
fire or electric shock. If you are not sure of the power available, consult your dealer or power company.
• Place the projector near a wall outlet where the plug can be easily unplugged.
• Take the following precautions when handling the plug: Do not hold the plug with wet hands. Do not
insert the plug into a dusty outlet. Insert the plug firmly into the outlet. Do not pull the power cord when
disconnecting the plug; always be sure to hold the plug when disconnecting it. Do not overload wall
outlets, extension cords, or power strips. Failure to comply with these precautions could result in fire or
electric shock.
• Do not place the projector where the cord can be walked on. This may result in fraying or damage to
the plug.
• Unplug the projector from the wall outlet and allow to cool before cleaning. Use a dry cloth (or, for
stubborn dirt or stains, a moist cloth that has been wrung dry) for cleaning. Do not use liquid or aerosol
cleaners, any sprays containing flammable gas, or solvents such as alcohol, paint thinner, or benzine.
• Do not block the slots and openings in the projector case. They provide ventilation and prevent the
projector from overheating. Do not operate the projector on a sofa, rug, or other soft surface, or set it
on top of loose papers. Do not cover the projector with a blanket, curtain, or tablecloth. If you are
setting up the projector near a wall, leave at least 7.9 inches (20 cm) of space between the wall and
the projector.
• Do not operate the projector in a closed-in cabinet unless proper ventilation is provided.
179

• Never allow objects of any kind to enter any openings in the projector. Do not leave objects, especially
flammable objects, near the projector. Never spill liquid of any kind into the projector.
• If you are using two or more projectors side-by-side, leave at least 2 feet (60 cm) of space between the
projectors to allow for proper ventilation.
• You may need to clean the air filter and vent. A clogged air filter or vent can block ventilation needed
to cool the projector. Do not use canned air, or the gases may leave a residue.
• Do not store the projector outdoors for an extended length of time.
• Except as specifically explained in this manual, do not attempt to service this product yourself. Refer
all servicing to qualified personnel. Opening or removing covers may expose you to dangerous
voltages and other hazards.
• Never open any covers on the projector except as specifically explained in this manual. Never attempt
to disassemble or modify the projector. Refer all repairs to qualified service personnel.
• Unplug the projector from the wall outlet and refer servicing to qualified service personnel under the
following conditions: if it does not operate normally when you follow the operating instructions, or
exhibits a distinct change in performance; if smoke, strange odors, or strange noises come from the
projector; if the power cord or plug is damaged or frayed; if liquid or foreign objects get inside the
projector, or if it has been exposed to rain or water; if it has been dropped or the housing has been
damaged.
• Do not touch the plug during an electrical storm. Otherwise, you may receive an electric shock.
• Unplug the projector when it will not be used for extended periods.
• Do not use the projector where it may be exposed to rain, water, or excessive humidity.
• Do not use or store the projector where it may be exposed to smoke, steam, corrosive gases,
excessive dust, vibration, or shock.
• Do not use the projector where flammable or explosive gases may be present.
• Do not use or store the projector or remote control in a hot location, such as near a heater, in direct
sunlight, or in a closed vehicle.
• If you use the projector in a country other than where you purchased it, use the correct power cord for
that country.
• Do not stand on the projector or place heavy objects on it.
• Do not use the projector outside of the required temperature range below:
41 to 104 °F (5 to 40 °C) at an altitude of 7500 feet (2286 m) or less, or 41 to 95 °F (5 to 35 °C) at a
higher altitude

180

Doing so may cause an unstable display and could lead to projector damage. Do not use or store the
projector where it may be exposed to sudden changes in temperature.
• Do not store the projector outside of the required temperature range of 14 to 140 °F (–10 to 60 °C) or
in direct sunlight for long periods of time. Doing so may cause damage to the case.
• Do not place anything that can become warped or damaged by heat near the exhaust vents. Do not
bring your hands or face close to the vents while projection is in progress. Do not bring your face close
to the projector while it is in use.
• Before you move the projector, make sure its power is turned off, the plug is disconnected from the
outlet, and all cables are disconnected.
• Never try to remove the lamp immediately after use because it will be extremely hot. Before removing
the lamp, turn off the power and wait at least an hour to allow the lamp to cool completely.
• Do not disassemble the lamp or subject it to impacts.
• Do not place the source of an open flame, such as a lit candle, on or near the projector.
• Do not block the lens during projection using a book or any object other than the lens cover. Use the
lens cover to temporarily stop projection, but avoid projecting with the lens cover closed for a long
period. This could damage the projector or cause a fire.
• Do not modify the power cord. Do not place heavy objects on top of the power cord or bend, twist, or
pull it excessively. Keep the power cord away from hot electrical appliances.
• If the lamp breaks, ventilate the room to prevent gases contained in the lamp from being inhaled or
coming in contact with your eyes or mouth. If you do inhale gases or gases come in contact with your
eyes or mouth, seek medical advice immediately.
• If the projector is mounted overhead and the lamp breaks, be careful to prevent pieces of glass from
falling into your eyes or mouth when you open the lamp cover. If pieces of glass do get into your eyes
or mouth, seek medical advice immediately.
• Always lower the volume before turning off the projector. Turning on the projector with the volume too
high can damage your ears.

GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA
02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document,
but changing it is not allowed.

Preamble
The licenses for most software are designed to take away your freedom to share and change it. By
contrast, the GNU General Public License is intended to guarantee your freedom to share and change
free software—to make sure the software is free for all its users. This General Public License applies to
most of the Free Software Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public
License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are
designed to make sure that you have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it if you want it, that you can change the
software or use pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask
you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute
copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the
recipients all the rights that you have. You must make sure that they, too, receive or can get the source
code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which
gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that
there is no warranty for this free software. If the software is modified by someone else and passed on,
we want its recipients to know that what they have is not the original, so that any problems introduced by
others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that
redistributors of a free program will individually obtain patent licenses, in effect making the program
proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free
use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
GNU GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND
MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright
holder saying it may be distributed under the terms of this General Public License. The "Program",
below, refers to any such program or work, and a "work based on the Program" means either the
Program or any derivative work under copyright law: that is to say, a work containing the Program or a
portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter,
translation is included without limitation in the term "modification".) Each licensee is addressed as "you".
188

Activities other than copying, distribution and modification are not covered by this License; they are
outside its scope. The act of running the Program is not restricted, and the output from the Program is
covered only if its contents constitute a work based on the Program (independent of having been made
by running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any
medium, provided that you conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the
absence of any warranty; and give any other recipients of the Program a copy of this License along with
the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on
the Program, and copy and distribute such modifications or work under the terms of Section 1 above,
provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the
date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived
from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the
terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when
started running for such interactive use in the most ordinary way, to print or display an announcement
including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you
provide a warranty) and that users may redistribute the program under these conditions, and telling the
user how to view a copy of this License. (Exception: if the Program itself is interactive but does not
normally print such an announcement, your work based on the Program is not required to print an
announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not
derived from the Program, and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole which is a work based on
the Program, the distribution of the whole must be on the terms of this License, whose permissions for
other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by
you; rather, the intent is to exercise the right to control the distribution of derivative or collective works
based on the Program.

189

In addition, mere aggregation of another work not based on the Program with the Program (or with a
work based on the Program) on a volume of a storage or distribution medium does not bring the other
work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or
executable form under the terms of Sections 1 and 2 above provided that you also do one of the
following:
a) Accompany it with the complete corresponding machine-readable source code, which must be
distributed under the terms of Sections 1 and 2 above on a medium customarily used for software
interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no
more than your cost of physically performing source distribution, a complete machine-readable copy of
the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source
code. (This alternative is allowed only for noncommercial distribution and only if you received the
program in object code or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For an
executable work, complete source code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to control compilation and installation of the
executable. However, as a special exception, the source code distributed need not include anything that
is normally distributed (in either source or binary form) with the major components (compiler, kernel, and
so on) of the operating system on which the executable runs, unless that component itself accompanies
the executable.
If distribution of executable or object code is made by offering access to copy from a designated place,
then offering equivalent access to copy the source code from the same place counts as distribution of
the source code, even though third parties are not compelled to copy the source along with the object
code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under
this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will
automatically terminate your rights under this License. However, parties who have received copies, or
rights, from you under this License will not have their licenses terminated so long as such parties remain
in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program
(or any work based on the Program), you indicate your acceptance of this License to do so, and all its
terms and conditions for copying, distributing or modifying the Program or works based on it.
190

6. Each time you redistribute the Program (or any work based on the Program), the recipient
automatically receives a license from the original licensor to copy, distribute or modify the Program
subject to these terms and conditions. You may not impose any further restrictions on the recipients'
exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason
(not limited to patent issues), conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License
and any other pertinent obligations, then as a consequence you may not distribute the Program at all.
For example, if a patent license would not permit royalty-free redistribution of the Program by all those
who receive copies directly or indirectly through you, then the only way you could satisfy both it and this
License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the
balance of the section is intended to apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or
to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the
free software distribution system, which is implemented by public license practices. Many people have
made generous contributions to the wide range of software distributed through that system in reliance on
consistent application of that system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this
License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by
copyrighted interfaces, the original copyright holder who places the Program under this License may add
an explicit geographical distribution limitation excluding those countries, so that distribution is permitted
only in or among countries not thus excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public
License from time to time. Such new versions will be similar in spirit to the present version, but may differ
in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this
License which applies to it and "any later version", you have the option of following the terms and
conditions either of that version or of any later version published by the Free Software Foundation. If the
Program does not specify a version number of this License, you may choose any version ever published
by the Free Software Foundation.

191

10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions
are different, write to the author to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this.
Our decision will be guided by the two goals of preserving the free status of all derivatives of our free
software and of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR
IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY
AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE,
YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR
DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES
OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best
way to achieve this is to make it free software which everyone can redistribute and change under these
terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each
source file to most effectively convey the exclusion of warranty; and each file should have at least the
"copyright" line and a pointer to where the full notice is found.

Copyright (C)
This program is free software; you can redistribute it and/or modify it under the terms of the GNU
General Public License as published by the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.

192

This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without
even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See
the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with this program; if not,
write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301
USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY
NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General
Public License. Of course, the commands you use may be called something other than `show w' and
`show c'; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a
"copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes
passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into proprietary programs. If
your program is a subroutine library, you may consider it more useful to permit linking proprietary
applications with the library. If this is what you want to do, use the GNU Lesser General Public License

Version 2.1, February 1999
Copyright (C) 1991, 1999 Free Software Foundation, Inc. 51 Franklin Street, Fifth Floor, Boston, MA
02110-1301 USA Everyone is permitted to copy and distribute verbatim copies of this license document,
but changing it is not allowed.
[This is the first released version of the Lesser GPL. It also counts as the successor of the GNU Library
Public License, version 2, hence the version number 2.1.]
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By
contrast, the GNU General Public Licenses are intended to guarantee your freedom to share and
change free software—to make sure the software is free for all its users.
This license, the Lesser General Public License, applies to some specially designated software
packages--typically libraries--of the Free Software Foundation and other authors who decide to use it.
You can use it too, but we suggest you first think carefully about whether this license or the ordinary
General Public License is the better strategy to use in any particular case, based on the explanations
below.
When we speak of free software, we are referring to freedom of use, not price. Our General Public
Licenses are designed to make sure that you have the freedom to distribute copies of free software (and
charge for this service if you wish); that you receive source code or can get it if you want it; that you can
194

change the software and use pieces of it in new free programs; and that you are informed that you can
do these things.
To protect your rights, we need to make restrictions that forbid distributors to deny you these rights or to
ask you to surrender these rights. These restrictions translate to certain responsibilities for you if you
distribute copies of the library or if you modify it.
For example, if you distribute copies of the library, whether gratis or for a fee, you must give the
recipients all the rights that we gave you. You must make sure that they, too, receive or can get the
source code. If you link other code with the library, you must provide complete object files to the
recipients, so that they can relink them with the library after making changes to the library and
recompiling it. And you must show them these terms so they know their rights.
We protect your rights with a two-step method: (1) we copyright the library, and (2) we offer you this
license, which gives you legal permission to copy, distribute and/or modify the library.
To protect each distributor, we want to make it very clear that there is no warranty for the free library.
Also, if the library is modified by someone else and passed on, the recipients should know that what they
have is not the original version, so that the original author's reputation will not be affected by problems
that might be introduced by others.
Finally, software patents pose a constant threat to the existence of any free program. We wish to make
sure that a company cannot effectively restrict the users of a free program by obtaining a restrictive
license from a patent holder. Therefore, we insist that any patent license obtained for a version of the
library must be consistent with the full freedom of use specified in this license.
Most GNU software, including some libraries, is covered by the ordinary GNU General Public License.
This license, the GNU Lesser General Public License, applies to certain designated libraries, and is quite
different from the ordinary General Public License. We use this license for certain libraries in order to
permit linking those libraries into non-free programs.
When a program is linked with a library, whether statically or using a shared library, the combination of
the two is legally speaking a combined work, a derivative of the original library. The ordinary General
Public License therefore permits such linking only if the entire combination fits its criteria of freedom. The
Lesser General Public License permits more lax criteria for linking other code with the library.
We call this license the "Lesser" General Public License because it does Less to protect the user's
freedom than the ordinary General Public License. It also provides other free software developers Less
of an advantage over competing non-free programs. These disadvantages are the reason we use the
ordinary General Public License for many libraries. However, the Lesser license provides advantages in
certain special circumstances.
For example, on rare occasions, there may be a special need to encourage the widest possible use of a
certain library, so that it becomes a de-facto standard. To achieve this, non-free programs must be
allowed to use the library. A more frequent case is that a free library does the same job as widely used

195

non-free libraries. In this case, there is little to gain by limiting the free library to free software only, so we
use the Lesser General Public License.
In other cases, permission to use a particular library in non-free programs enables a greater number of
people to use a large body of free software. For example, permission to use the GNU C Library in nonfree programs enables many more people to use the whole GNU operating system, as well as its variant,
the GNU/Linux operating system.
Although the Lesser General Public License is Less protective of the users' freedom, it does ensure that
the user of a program that is linked with the Library has the freedom and the wherewithal to run that
program using a modified version of the Library.
The precise terms and conditions for copying, distribution and modification follow. Pay close attention to
the difference between a "work based on the library" and a "work that uses the library". The former
contains code derived from the library, whereas the latter must be combined with the library in order to
run.
GNU LESSER GENERAL PUBLIC LICENSE TERMS AND CONDITIONS FOR COPYING,
DISTRIBUTION AND MODIFICATION
0. This License Agreement applies to any software library or other program which contains a notice
placed by the copyright holder or other authorized party saying it may be distributed under the terms of
this Lesser General Public License (also called "this License"). Each licensee is addressed as "you".
A "library" means a collection of software functions and/or data prepared so as to be conveniently linked
with application programs (which use some of those functions and data) to form executables.
The "Library", below, refers to any such software library or work which has been distributed under these
terms. A "work based on the Library" means either the Library or any derivative work under copyright
law: that is to say, a work containing the Library or a portion of it, either verbatim or with modifications
and/or translated straightforwardly into another language. (Hereinafter, translation is included without
limitation in the term "modification".)
"Source code" for a work means the preferred form of the work for making modifications to it. For a
library, complete source code means all the source code for all modules it contains, plus any associated
interface definition files, plus the scripts used to control compilation and installation of the library.
Activities other than copying, distribution and modification are not covered by this License; they are
outside its scope. The act of running a program using the Library is not restricted, and output from such a
program is covered only if its contents constitute a work based on the Library (independent of the use of
the Library in a tool for writing it). Whether that is true depends on what the Library does and what the
program that uses the Library does.
1. You may copy and distribute verbatim copies of the Library's complete source code as you receive it,
in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate

196

copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the
absence of any warranty; and distribute a copy of this License along with the Library.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer
warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Library or any portion of it, thus forming a work based on
the Library, and copy and distribute such modifications or work under the terms of Section 1 above,
provided that you also meet all of these conditions:
a) The modified work must itself be a software library.
b) You must cause the files modified to carry prominent notices stating that you changed the files and the
date of any change.
c) You must cause the whole of the work to be licensed at no charge to all third parties under the terms
of this License.
d) If a facility in the modified Library refers to a function or a table of data to be supplied by an application
program that uses the facility, other than as an argument passed when the facility is invoked, then you
must make a good faith effort to ensure that, in the event an application does not supply such function or
table, the facility still operates, and performs whatever part of its purpose remains meaningful.
(For example, a function in a library to compute square roots has a purpose that is entirely well-defined
independent of the application. Therefore, Subsection 2d requires that any application-supplied function
or table used by this function must be optional: if the application does not supply it, the square root
function must still compute square roots.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not
derived from the Library, and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those sections when you distribute them as
separate works. But when you distribute the same sections as part of a whole which is a work based on
the Library, the distribution of the whole must be on the terms of this License, whose permissions for
other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by
you; rather, the intent is to exercise the right to control the distribution of derivative or collective works
based on the Library.
In addition, mere aggregation of another work not based on the Library with the Library (or with a work
based on the Library) on a volume of a storage or distribution medium does not bring the other work
under the scope of this License.
3. You may opt to apply the terms of the ordinary GNU General Public License instead of this License to
a given copy of the Library. To do this, you must alter all the notices that refer to this License, so that
they refer to the ordinary GNU General Public License, version 2, instead of to this License. (If a newer

197

version than version 2 of the ordinary GNU General Public License has appeared, then you can specify
that version instead if you wish.) Do not make any other change in these notices.
Once this change is made in a given copy, it is irreversible for that copy, so the ordinary GNU General
Public License applies to all subsequent copies and derivative works made from that copy.
This option is useful when you wish to copy part of the code of the Library into a program that is not a
library.
4. You may copy and distribute the Library (or a portion or derivative of it, under Section 2) in object code
or executable form under the terms of Sections 1 and 2 above provided that you accompany it with the
complete corresponding machine-readable source code, which must be distributed under the terms of
Sections 1 and 2 above on a medium customarily used for software interchange.
If distribution of object code is made by offering access to copy from a designated place, then offering
equivalent access to copy the source code from the same place satisfies the requirement to distribute
the source code, even though third parties are not compelled to copy the source along with the object
code.
5. A program that contains no derivative of any portion of the Library, but is designed to work with the
Library by being compiled or linked with it, is called a "work that uses the Library". Such a work, in
isolation, is not a derivative work of the Library, and therefore falls outside the scope of this License.
However, linking a "work that uses the Library" with the Library creates an executable that is a derivative
of the Library (because it contains portions of the Library), rather than a "work that uses the library". The
executable is therefore covered by this License. Section 6 states terms for distribution of such
executables.
When a "work that uses the Library" uses material from a header file that is part of the Library, the object
code for the work may be a derivative work of the Library even though the source code is not. Whether
this is true is especially significant if the work can be linked without the Library, or if the work is itself a
library. The threshold for this to be true is not precisely defined by law.
If such an object file uses only numerical parameters, data structure layouts and accessors, and small
macros and small inline functions (ten lines or less in length), then the use of the object file is
unrestricted, regardless of whether it is legally a derivative work. (Executables containing this object
code plus portions of the Library will still fall under Section 6.)
Otherwise, if the work is a derivative of the Library, you may distribute the object code for the work under
the terms of Section 6. Any executables containing that work also fall under Section 6, whether or not
they are linked directly with the Library itself.
6. As an exception to the Sections above, you may also combine or link a "work that uses the Library"
with the Library to produce a work containing portions of the Library, and distribute that work under terms
of your choice, provided that the terms permit modification of the work for the customer's own use and
reverse engineering for debugging such modifications.
198

You must give prominent notice with each copy of the work that the Library is used in it and that the
Library and its use are covered by this License. You must supply a copy of this License. If the work
during execution displays copyright notices, you must include the copyright notice for the Library among
them, as well as a reference directing the user to the copy of this License. Also, you must do one of
these things:
a) Accompany the work with the complete corresponding machine-readable source code for the Library
including whatever changes were used in the work (which must be distributed under Sections 1 and 2
above); and, if the work is an executable linked with the Library, with the complete machine-readable
"work that uses the Library", as object code and/or source code, so that the user can modify the Library
and then relink to produce a modified executable containing the modified Library. (It is understood that
the user who changes the contents of definitions files in the Library will not necessarily be able to
recompile the application to use the modified definitions.)
b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that
(1) uses at run time a copy of the library already present on the user's computer system, rather than
copying library functions into the executable, and (2) will operate properly with a modified version of the
library, if the user installs one, as long as the modified version is interface-compatible with the version
that the work was made with.
c) Accompany the work with a written offer, valid for at least three years, to give the same user the
materials specified in Subsection 6a, above, for a charge no more than the cost of performing this
distribution.
d) If distribution of the work is made by offering access to copy from a designated place, offer equivalent
access to copy the above specified materials from the same place.
e) Verify that the user has already received a copy of these materials or that you have already sent this
user a copy.
For an executable, the required form of the "work that uses the Library" must include any data and utility
programs needed for reproducing the executable from it. However, as a special exception, the materials
to be distributed need not include anything that is normally distributed (in either source or binary form)
with the major components (compiler, kernel, and so on) of the operating system on which the
executable runs, unless that component itself accompanies the executable.
It may happen that this requirement contradicts the license restrictions of other proprietary libraries that
do not normally accompany the operating system. Such a contradiction means you cannot use both
them and the Library together in an executable that you distribute.
7. You may place library facilities that are a work based on the Library side-by-side in a single library
together with other library facilities not covered by this License, and distribute such a combined library,
provided that the separate distribution of the work based on the Library and of the other library facilities is
otherwise permitted, and provided that you do these two things:

199

a) Accompany the combined library with a copy of the same work based on the Library, uncombined with
any other library facilities. This must be distributed under the terms of the Sections above.
b) Give prominent notice with the combined library of the fact that part of it is a work based on the
Library, and explaining where to find the accompanying uncombined form of the same work.
8. You may not copy, modify, sublicense, link with, or distribute the Library except as expressly provided
under this License. Any attempt otherwise to copy, modify, sublicense, link with, or distribute the Library
is void, and will automatically terminate your rights under this License. However, parties who have
received copies, or rights, from you under this License will not have their licenses terminated so long as
such parties remain in full compliance.
9. You are not required to accept this License, since you have not signed it. However, nothing else
grants you permission to modify or distribute the Library or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Library (or
any work based on the Library), you indicate your acceptance of this License to do so, and all its terms
and conditions for copying, distributing or modifying the Library or works based on it.
10. Each time you redistribute the Library (or any work based on the Library), the recipient automatically
receives a license from the original licensor to copy, distribute, link with or modify the Library subject to
these terms and conditions. You may not impose any further restrictions on the recipients' exercise of
the rights granted herein. You are not responsible for enforcing compliance by third parties with this
License.
11. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason
(not limited to patent issues), conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of
this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License
and any other pertinent obligations, then as a consequence you may not distribute the Library at all. For
example, if a patent license would not permit royalty-free redistribution of the Library by all those who
receive copies directly or indirectly through you, then the only way you could satisfy both it and this
License would be to refrain entirely from distribution of the Library.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the
balance of the section is intended to apply, and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or
to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the
free software distribution system which is implemented by public license practices. Many people have
made generous contributions to the wide range of software distributed through that system in reliance on
consistent application of that system; it is up to the author/donor to decide if he or she is willing to
distribute software through any other system and a licensee cannot impose that choice.

200

This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this
License.
12. If the distribution and/or use of the Library is restricted in certain countries either by patents or by
copyrighted interfaces, the original copyright holder who places the Library under this License may add
an explicit geographical distribution limitation excluding those countries, so that distribution is permitted
only in or among countries not thus excluded. In such case, this License incorporates the limitation as if
written in the body of this License.
13. The Free Software Foundation may publish revised and/or new versions of the Lesser General
Public License from time to time. Such new versions will be similar in spirit to the present version, but
may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Library specifies a version number of this
License which applies to it and "any later version", you have the option of following the terms and
conditions either of that version or of any later version published by the Free Software Foundation. If the
Library does not specify a license version number, you may choose any version ever published by the
Free Software Foundation.
14. If you wish to incorporate parts of the Library into other free programs whose distribution conditions
are incompatible with these, write to the author to ask for permission. For software which is copyrighted
by the Free Software Foundation, write to the Free Software Foundation; we sometimes make
exceptions for this. Our decision will be guided by the two goals of preserving the free status of all
derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR
THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE
STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE
LIBRARY "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED,
INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND
PERFORMANCE OF THE LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE,
YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL
ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE
THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE
OR INABILITY TO USE THE LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA
BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF SUCH
HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
201

END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Libraries
If you develop a new library, and you want it to be of the greatest possible use to the public, we
recommend making it free software that everyone can redistribute and change. You can do so by
permitting redistribution under these terms (or, alternatively, under the terms of the ordinary General
Public License).
To apply these terms, attach the following notices to the library. It is safest to attach them to the start of
each source file to most effectively convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

Copyright (C)
This library is free software; you can redistribute it and/or modify it under the terms of the GNU Lesser
General Public License as published by the Free Software Foundation; either version 2.1 of the License,
or (at your option) any later version.
This library is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even
the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU Lesser General Public License for more details.
You should have received a copy of the GNU Lesser General Public License along with this library; if
not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301
USA
Also add information on how to contact you by electronic and paper mail.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a
"copyright disclaimer" for the library, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the library `Frob' (a library for tweaking knobs)
written by James Random Hacker.

Copyright (C) 1994-1997, Thomas G. Lane. This file is part of the Independent JPEG Group's software.
For conditions of distribution and use, see the accompanying README file.
This distribution contains the sixth public release of the Independent JPEG Group's free JPEG software.
You are welcome to redistribute this software and to use it for any purpose, subject to the conditions
under LEGAL ISSUES, below.
LEGAL ISSUES
============
In plain English:
1. We don't promise that this software works. (But if you find any bugs, please let us know!)
2. You can use this software for whatever you want. You don't have to pay us.
3. You may not pretend that you wrote this software. If you use it in a program, you must acknowledge
somewhere in your documentation that you've used the IJG code.
In legalese:
The authors make NO WARRANTY or representation, either express or implied, with respect to this
software, its quality, accuracy, merchantability, or fitness for a particular purpose. This software is
provided "AS IS", and you, its user, assume the entire risk as to its quality and accuracy.
This software is copyright (C) 1991-1998, Thomas G. Lane. All Rights Reserved except as specified
below.
Permission is hereby granted to use, copy, modify, and distribute this software (or portions thereof) for
any purpose, without fee, subject to these conditions:
(1) If any part of the source code for this software is distributed, then this README file must be included,
with this copyright and no-warranty notice unaltered; and any additions, deletions, or changes to the
original files must be clearly indicated in accompanying documentation.
(2) If only executable code is distributed, then the accompanying documentation must state that "this
software is based in part on the work of the Independent JPEG Group".
(3) Permission for use of this software is granted only if the user accepts full responsibility for any
undesirable consequences; the authors accept NO LIABILITY for damages of any kind.

204

These conditions apply to any software derived from or based on the IJG code, not just to the unmodified
library. If you use our work, you ought to acknowledge us.
Permission is NOT granted for the use of any IJG author's name or company name in advertising or
publicity relating to this software or products derived from it. This software may be referred to only as
"the Independent JPEG Group's software".
We specifically permit and encourage the use of this software as the basis of commercial products,
provided that all warranty or liability claims are assumed by the product vendor.
ansi2knr.c is included in this distribution by permission of L. Peter Deutsch, sole proprietor of its
copyright holder, Aladdin Enterprises of Menlo Park, CA. ansi2knr.c is NOT covered by the above
copyright and conditions, but instead by the usual distribution terms of the Free Software Foundation;
principally, that you must include source code if you redistribute it. (See the file ansi2knr.c for full details.)
However, since ansi2knr.c is not needed as part of any program generated from the IJG code, this does
not limit you more than the foregoing paragraphs do.
The Unix configuration script "configure" was produced with GNU Autoconf. It is copyright by the Free
Software Foundation but is freely distributable. The same holds for its supporting scripts (config.guess,
config.sub, ltconfig, ltmain.sh). Another support script, install-sh, is copyright by M.I.T. but is also freely
distributable.
It appears that the arithmetic coding option of the JPEG spec is covered by patents owned by IBM,
AT&T, and Mitsubishi. Hence arithmetic coding cannot legally be used without obtaining one or more
licenses. For this reason, support for arithmetic coding has been removed from the free JPEG software.
(Since arithmetic coding provides only a marginal gain over the unpatented Huffman mode, it is unlikely
that very many implementations will support it.) So far as we are aware, there are no patent restrictions
on the remaining code.
The IJG distribution formerly included code to read and write GIF files. To avoid entanglement with the
Unisys LZW patent, GIF reading support has been removed altogether, and the GIF writer has been
simplified to produce "uncompressed GIFs". This technique does not use the LZW algorithm; the
resulting GIF files are larger than usual, but are readable by all standard GIF decoders.
We are required to state that "The Graphics Interchange Format(c) is the Copyright property of
CompuServe Incorporated. GIF(sm) is a Service Mark property of CompuServe Incorporated."

Introduction
===========
The FreeType Project is distributed in several archive packages; some of them may contain, in addition
to the FreeType font engine, various tools and contributions which rely on, or relate to, the FreeType
Project.
This license applies to all files found in such packages, and which do not fall under their own explicit
license. The license affects thus the FreeType font engine, the test programs, documentation and
makefiles, at the very least.
This license was inspired by the BSD, Artistic, and IJG (Independent JPEG Group) licenses, which all
encourage inclusion and use of free software in commercial and freeware products alike. As a
consequence, its main points are that:
• We don't promise that this software works. However, we will be interested in any kind of bug reports.
(`as is' distribution)
• You can use this software for whatever you want, in parts or full form, without having to pay us.
(`royalty-free' usage)
• You may not pretend that you wrote this software. If you use it, or only parts of it, in a program, you
must acknowledge somewhere in your documentation that you have used the FreeType code.
(`credits')
We specifically permit and encourage the inclusion of this software, with or without modifications, in
commercial products. We disclaim all warranties covering The FreeType Project and assume no liability
related to The FreeType Project.
Finally, many people asked us for a preferred form for a credit/disclaimer to use in compliance with this
license. We thus encourage you to use the following text:
"""
Portions of this software are copyright © The FreeType Project (www.freetype.org). All rights
reserved.
"""
Please replace with the value from the FreeType version you actually use.
Legal Terms
===========
0. Definitions

238

-------------Throughout this license, the terms `package', `FreeType Project', and `FreeType archive' refer to the set
of files originally distributed by the authors (David Turner, Robert Wilhelm, and Werner Lemberg) as the
`FreeType Project', be they named as alpha, beta or final release.
`You' refers to the licensee, or person using the project, where `using' is a generic term including
compiling the project's source code as well as linking it to form a `program' or `executable'. This program
is referred to as `a program using the FreeType engine'.
This license applies to all files distributed in the original FreeType Project, including all source code,
binaries and documentation, unless otherwise stated in the file in its original, unmodified form as
distributed in the original archive.
If you are unsure whether or not a particular file is covered by this license, you must contact us to verify
this.
The FreeType Project is copyright (C) 1996-2000 by David Turner, Robert Wilhelm, and Werner
Lemberg. All rights reserved except as specified below.
1. No Warranty
-------------THE FREETYPE PROJECT IS PROVIDED `AS IS' WITHOUT WARRANTY OF ANY KIND, EITHER
EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. IN NO EVENT WILL ANY OF
THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY DAMAGES CAUSED BY THE USE
OR THE INABILITY TO USE, OF THE FREETYPE PROJECT.
2. Redistribution
----------------This license grants a worldwide, royalty-free, perpetual and irrevocable right and license to use, execute,
perform, compile, display, copy, create derivative works of, distribute and sublicense the FreeType
Project (in both source and object code forms) and derivative works thereof for any purpose; and to
authorize others to exercise some or all of the rights granted herein, subject to the following conditions:
• Redistribution of source code must retain this license file (`FTL.TXT') unaltered; any additions,
deletions or changes to the original files must be clearly indicated in accompanying documentation.
The copyright notices of the unaltered, original files must be preserved in all copies of source files.
• Redistribution in binary form must provide a disclaimer that states that the software is based in part of
the work of the FreeType Team, in the distribution documentation. We also encourage you to put an
URL to the FreeType web page in your documentation, though this isn't mandatory.

239

These conditions apply to any software derived from or based on the FreeType Project, not just the
unmodified files. If you use our work, you must acknowledge us. However, no fee need be paid to us.
3. Advertising
-------------Neither the FreeType authors and contributors nor you shall use the name of the other for commercial,
advertising, or promotional purposes without specific prior written permission.
We suggest, but do not require, that you use one or more of the following phrases to refer to this
software in your documentation or advertising materials: `FreeType Project', `FreeType Engine',
`FreeType library', or `FreeType Distribution'.
As you have not signed this license, you are not required to accept it. However, as the FreeType Project
is copyrighted material, only this license, or another one contracted with the authors, grants you the right
to use, distribute, and modify it.
Therefore, by using, distributing, or modifying the FreeType Project, you indicate that you understand
and accept all the terms of this license.
4. Contacts
----------There are two mailing lists related to FreeType:
• freetype@nongnu.org
Discusses general use and applications of FreeType, as well as future and wanted additions to the
library and distribution.
If you are looking for support, start in this list if you haven't found anything to help you in the
documentation.
• freetype-devel@nongnu.org
Discusses bugs, as well as engine internals, design issues, specific licenses, porting, etc.

Binding Arbitration and Class Waiver
1. DISPUTES, BINDING INDIVIDUAL ARBITRATION, AND WAIVER OF CLASS ACTIONS AND
CLASS ARBITRATIONS
1.1 Disputes. The terms of this Section 1 shall apply to all Disputes between you and Epson. The term
"Dispute" is meant to have the broadest meaning permissible under law and includes any dispute, claim,
controversy or action between you and Epson arising out of or relating to this Agreement, Epson
branded products (hardware and including any related software), or other transaction involving you and
Epson, whether in contract, warranty, misrepresentation, fraud, tort, intentional tort, statute, regulation,
ordinance, or any other legal or equitable basis. "DISPUTE" DOES NOT INCLUDE IP CLAIMS, or more
specifically, a claim or cause of action for (a) trademark infringement or dilution, (b) patent infringement,
(c) copyright infringement or misuse, or (d) trade secret misappropriation (an "IP Claim"). You and Epson
also agree, notwithstanding Section 1.6,that a court, not an arbitrator, may decide if a claim or cause of
action is for an IP Claim.
1.2 Binding Arbitration. You and Epson agree that all Disputes shall be resolved by binding arbitration
according to this Agreement. ARBITRATION MEANS THAT YOU WAIVE YOUR RIGHT TO A JUDGE
OR JURY IN A COURT PROCEEDING AND YOUR GROUNDS FOR APPEAL ARE LIMITED.
Pursuant to this Agreement, binding arbitration shall be administered by JAMS, a nationally recognized
arbitration authority, pursuant to its code of procedures then in effect for consumer related disputes, but
excluding any rules that permit joinder or class actions in arbitration (for more detail on procedure, see
Section 1.6 below). You and Epson understand and agree that (a) the Federal Arbitration Act (9 U.S.C.
§1, et seq.) governs the interpretation and enforcement of this Section 1, (b) this Agreement
memorializes a transaction in interstate commerce, and (c) this Section 1 shall survive termination of this
Agreement.
1.3 Pre-Arbitration Steps and Notice. Before submitting a claim for arbitration, you and Epson agree to
try, for sixty (60) days, to resolve any Dispute informally. If Epson and you do not reach an agreement to
resolve the Dispute within the sixty (60) days), you or Epson may commence an arbitration. Notice to
Epson must be addressed to: Epson America, Inc., ATTN: Legal Department, 3840 Kilroy Airport Way,
Long Beach, CA 90806 (the "Epson Address"). The Dispute Notice to you will be sent to the most recent
address Epson has in its records for you. For this reason, it is important to notify us if your address
changes by emailing us at EAILegal@ea.epson.com or writing us at the Epson Address above. Notice of
the Dispute shall include the sender's name, address and contact information, the facts giving rise to the
Dispute, and the relief requested (the "Dispute Notice"). Following receipt of the Dispute Notice, Epson
and you agree to act in good faith to resolve the Dispute before commencing arbitration.
1.4 Small Claims Court. Notwithstanding the foregoing, you may bring an individual action in the small
claims court of your state or municipality if the action is within that court's jurisdiction and is pending only
in that court.

241

1.5 WAIVER OF CLASS ACTIONS AND CLASS ARBITRATIONS. YOU AND EPSON AGREE THAT
EACH PARTY MAY BRING DISPUTES AGAINST THE OTHER PARTY ONLY IN AN INDIVIDUAL
CAPACITY, AND NOT AS A PLAINTIFF OR CLASS MEMBER IN ANY CLASS OR
REPRESENTATIVE PROCEEDING, INCLUDING WITHOUT LIMITATION FEDERAL OR STATE
CLASS ACTIONS, OR CLASS ARBITRATIONS. CLASS ACTION LAWSUITS, CLASS-WIDE
ARBITRATIONS, PRIVATE ATTORNEY-GENERAL ACTIONS, AND ANY OTHER PROCEEDING
WHERE SOMEONE ACTS IN A REPRESENTATIVE CAPACITY ARE NOT ALLOWED.
ACCORDINGLY, UNDER THE ARBITRATION PROCEDURES OUTLINED IN THIS SECTION, AN
ARBITRATOR SHALL NOT COMBINE OR CONSOLIDATE MORE THAN ONE PARTY'S CLAIMS
WITHOUT THE WRITTEN CONSENT OF ALL AFFECTED PARTIES TO AN ARBITRATION
PROCEEDING.
1.6 Arbitration Procedure. If you or Epson commences arbitration, the arbitration shall be governed by
the rules of JAMS that are in effect when the arbitration is filed, excluding any rules that permit arbitration
on a class or representative basis (the "JAMS Rules"), available at http://www.jamsadr.com or by calling
1-800-352-5267, and under the rules set forth in this Agreement. All Disputes shall be resolved by a
single neutral arbitrator, and both parties shall have a reasonable opportunity to participate in the
selection of the arbitrator. The arbitrator is bound by the terms of this Agreement. The arbitrator, and not
any federal, state or local court or agency, shall have exclusive authority to resolve all disputes arising
out of or relating to the interpretation, applicability, enforceability or formation of this Agreement,
including any claim that all or any part of this Agreement is void or voidable. Notwithstanding this broad
delegation of authority to the arbitrator, a court may determine the limited question of whether a claim or
cause of action is for an IP Claim, which is excluded from the definition of "Disputes" in Section 1.1
above. The arbitrator shall be empowered to grant whatever relief would be available in a court under
law or in equity. The arbitrator may award you the same damages as a court could, and may award
declaratory or injunctive relief only in favor of the individual party seeking relief and only to the extent
necessary to provide relief warranted by that party's individual claim. In some instances, the costs of
arbitration can exceed the costs of litigation and the right to discovery may be more limited in arbitration
than in court. The arbitrator's award is binding and may be entered as a judgment in any court of
competent jurisdiction.
You may choose to engage in arbitration hearings by telephone. Arbitration hearings not conducted by
telephone shall take place in a location reasonably accessible from your primary residence, or in Orange
County, California, at your option.
a) Initiation of Arbitration Proceeding. If either you or Epson decides to arbitrate a Dispute, both parties
agree to the following procedure:
(i) Write a Demand for Arbitration. The demand must include a description of the Dispute and the amount
of damages sought to be recovered. You can find a copy of a Demand for Arbitration at
http://www.jamsadr.com ("Demand for Arbitration").
(ii) Send three copies of the Demand for Arbitration, plus the appropriate filing fee, to: JAMS, 500 North
State College Blvd., Suite 600 Orange, CA 92868, U.S.A.
242

(iii) Send one copy of the Demand for Arbitration to the other party (same address as the Dispute
Notice), or as otherwise agreed by the parties.
b) Hearing Format. During the arbitration, the amount of any settlement offer made shall not be disclosed
to the arbitrator until after the arbitrator determines the amount, if any, to which you or Epson is entitled.
The discovery or exchange of non-privileged information relevant to the Dispute may be allowed during
the arbitration.
c) Arbitration Fees. Epson shall pay, or (if applicable) reimburse you for, all JAMS filings and arbitrator
fees for any arbitration commenced (by you or Epson) pursuant to provisions of this Agreement.
d) Award in Your Favor. For Disputes in which you or Epson seeks $75,000 or less in damages exclusive
of attorney's fees and costs, if the arbitrator's decision results in an award to you in an amount greater
than Epson's last written offer, if any, to settle the Dispute, Epson will: (i) pay you $1,000 or the amount
of the award, whichever is greater; (ii) pay you twice the amount of your reasonable attorney's fees, if
any; and (iii) reimburse you for any expenses (including expert witness fees and costs) that your attorney
reasonably accrues for investigating, preparing, and pursuing the Dispute in arbitration. Except as
agreed upon by you and Epson in writing, the arbitrator shall determine the amount of fees, costs, and
expenses to be paid by Epson pursuant to this Section 1.6d).
e) Attorney's Fees. Epson will not seek its attorney's fees and expenses for any arbitration commenced
involving a Dispute under this Agreement. Your right to attorney's fees and expenses under Section
1.6d) above does not limit your rights to attorney's fees and expenses under applicable law;
notwithstanding the foregoing, the arbitrator may not award duplicative awards of attorney's fees and
expenses.
1.7 Opt-out. You may elect to opt-out (exclude yourself) from the final, binding, individual
arbitration procedure and waiver of class and representative proceedings specified in this
Agreement by sending a written letter to the Epson Address within thirty (30) days of your assent
to this Agreement (including without limitation the purchase, download, installation of the
Software or other applicable use of Epson Hardware, products and services) that specifies (i)
your name, (ii) your mailing address, and (iii) your request to be excluded from the final, binding
individual arbitration procedure and waiver of class and representative proceedings specified in
this Section 1. In the event that you opt-out consistent with the procedure set forth above, all
other terms shall continue to apply, including the requirement to provide notice prior to litigation.
1.8 Amendments to Section 1. Notwithstanding any provision in this Agreement to the contrary, you
and Epson agree that if Epson makes any future amendments to the dispute resolution procedure and
class action waiver provisions (other than a change to Epson's address) in this Agreement, Epson will
obtain your affirmative assent to the applicable amendment. If you do not affirmatively assent to the
applicable amendment, you are agreeing that you will arbitrate any Dispute between the parties in
accordance with the language of this Section 1 (or resolve disputes as provided for in Section 1.7, if you
timely elected to opt-out when you first assented to this Agreement).

243

1.9 Severability. If any provision in this Section 1 is found to be unenforceable, that provision shall be
severed with the remainder of this Agreement remaining in full force and effect. The foregoing shall not
apply to the prohibition against class or representative actions as provided in Section 1.5. This
means that if Section 1.5 is found to be unenforceable, the entire Section 1 (but only Section 1)
shall be null and void.
