FCC COMPLIANCE STATEMENT
FOR AMERICAN USERS
This equipment uses and generates radio frequency energy and if not installed and used properly, that is,
in strict accordance with the manufacturer’s instructions, may cause interference to radio and television recep-
tion. It has been type tested and found to comply with limits for a Class B computing device in accordance
with Sub-part J of Part 15 of FCC Rules, which are designed to provide reasonable protection against such
interference in a residential installation. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause interference to radio or television reception, which can
be determined by turning the equipment on and off, the user is encouraged to try to correct the interference
by one or more of the following measures:
l reorient the receiving antenna
l relocate the computer with respect to the receiver
l move the computer away from the receiver
l plug the computer into a different outlet so that the computer and receiver are on different branch circuits.
If necessary, the user should consult the dealer or an experienced radio/television technician for additional
suggestions. The user may find the following booklet, prepared by the Federal Communications Commis-
sion, helpful: “ How to Identify and Resolve Radio-TV Interference Problems.” This booklet is available from
the U.S. Government Printing Office, Washington, D.C., 20402, Stock No. 004-000-00345-4.

Precautionary notations throughout the text are categorized relative to 1) personal injury, and 2) damage
to equipment:
DANGER Signals a precaution which, if ignored, could result in serious or fatal personal in-
jury. Great caution should be exercised in performing procedures preceded by a
DANGER heading.
WARNING
Signals a precaution which, if ignored, could result in damage to equipment.
The precautionary measures itemized below should always be observed when performing repair/maintenance
procedures.
DANGER
1. ALWAYS DISCONNECT THE PRODUCT FROM BOTH THE POWER SOURCE AND
PERIPHERAL DEVlCES BEFORE PERFORMING ANY MAINTENANCE OR REPAIR
PROCEDURE.
2. NO WORK SHOULD BE PERFORMED ON THE UNIT BY PERSONS UNFAMILIAR WITH
BASIC SAFETY MEASURES AS DICTATED FOR ALL ELECTRONICS TECHNICIANS IN
THEIR LINE OF WORK.
3. WHEN PERFORMING TESTING AS DICTATED WITHIN THIS MANUAL, DO NOT CON-
NECT THE UNIT TO A POWER SOURCE UNTIL INSTRUCTED TO DO SO. WHEN THE
POWER SUPPLY CABLE MUST BE CONNECTED, USE EXTREME CAUTION IN WORK-
ING ON POWER SUPPLY AND OTHER ELECTRONIC COMPONENTS.
WARNING
1. Repairs on Epson products should be performed on/y by an Epson-certified repair
technician.
2. Make certain that the source voltage is the same as the rated voltage, listed on the serial
number/rating plate. If the Epson product has a primary AC rating different from the
available power source, do not connect it to the power source.
3. Always verify that the Epson product has been disconnected from the power source before
removing or replacing printed circuit boards and/or individual chips.
4. In order to protect sensitive microprocessors and circuitry, use static discharge equip-
ment, such as anti-static wrist straps, when accessing internal components.
5. Replace malfunctioning components only with those components recommended by the
manufacturer; introduction of second-source ICs or other nonapproved components may
damage the product and void any applicable Epson warranty.

FCC Compliance Statement for American Users
This equipment has been tested and found to comply with limits for a Class B digital device,
pursuant to Part 16 of the FCC Rules. These limits are designed to provide reasonable protections
against harmful interference in a residential installation. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in accordance with the instructions,
may cause harmful interference to radio or television reception, which can be determined by turning
the equipment off and on. The user is encouraged to try to correct the interference by one or more of
the following measures:
l Reorient or relocate the receiving antenna
l Increase the separation between the equipment and the receiver
l Connect the equipment to an outlet on a circuit different from that to which the receiver is
connected
l Consult the dealer or an experienced radio/TV technician for help.
WARNING: The connection of a nonshielded interface cable to this equipment will
invalidate the FCC Certification of this device and may cause interference levels that
exceed the limits established by the FCC for this equipment. If this equipment has more
than one interface connector, do not leave cables connected to unused interfaces.
For Canadian Users
This digital apparatus does not exceed the Class B limits for radio noise emissions from digital
apparatus as set out in the radio interference regulations of the Canadian Department of
Communications.

NOTES: 1. HDD is horizontal dot density in dots per inch.
2. Face matrix and character size indicate maximum character size. This value changes accord-
ing to differences in paper, ribbon, etc.
3. Unit ESC sp (which also can be sent as the unit followed by the character string CHR$(&h20))
indicates the minimum length to be added to the right of the character that can be specified
with the ESC sp control code.
4. “_”
indicates that character matrix is reshaped by printer firmware. Character width becomes
half of noncondensed character width.
