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
15 of FCC Rules. These limits are designed to provide reasonable protection 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. 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 or relocate the receiving antenna.
l Increase the separation between the equipment and the receiver.
l Connect the equipment into an outlet on a circuit different from the one connected to the receiver.
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.
Le present appareil numcrique n’cmet pas de bruits radkklectrique d&passant lea limites applicables aux
appareils numcriques de Classe B prescrites dans le rkglement sur le brouillage radioGctriques tdictk par le
Minis&e des Communications du Canada.
The connection of a non-shielded equipment interface cable to this equipment will invalidate the FCC
Certification of this device and may cause interference levels which exceed the limits established by the FCC
for this equipment. It is the responsibility of the user to obtain and use a shielded equipment interface cable
with this device. If this equipment has more than one interface connector, do not leave the cables connected
to unused interfaces.
Changes or modifications not expressly approved by the manufacturer could void the user’s authority to
operate the equipment.

Precautions
Precautionary notations throughout the text are categorized relative to 1) personal injury, and 2)
damage to equipment.
WARNING Signals a precaution which, if ignored, could result in serious or fatal personal
injury. Great caution should be exercised in performing procedures preceded by a
WARNING heading.
CAUTION 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.
WARNING
1. Always disconnect the product from both the power source and the host
computer 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 connect
the unit to a power source until instructed to do so. When the power
supply cable must be connected, use extreme caution in working on the
power supply and other electronic components.
CAUTION
1. Repairs on Epson products should be performed only by an Epson certi-
fied 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 pP chip and circuitry, use static discharge
equipment, such as anti-static wrist straps, when accessing internal
components.
5. Replace malfunctioning components only with those components recom-
mended by the manufacturer; introduction of second-source ICs or other
nonapproved components may damage the product and void any appli-
cable Epson warranty.

Precautions for Handling Paper
Friction feed
l Set the release lever to the FRICTION position.
l Load the paper from the front or top entrance.
l Do not use continuous paper.
l Do not perform any reverse paper feeds within the top 0.34” (8.5 mm) area and
bottom 0.88” (22 mm) area.
l Do not perform reverse feeds greater than l/6” after the paper end has been
detected.
l Use the paper-tension unit.
l Insert multi-part cut-sheet forms only from the front.
Push tractor feed
l Set the release lever to the REAR PUSH/FRONT PUSH position.
l Load the paper from the rear or front entrance.
l Release the friction feed mechanism.
l Multi-part paper must be carbonless.
l Use the paper-tension unit.
l Do not perform reverse feeds greater than l/6”.
l Do not perform reverse feeding after the paper end has been detected, because
accuracy of paper feed cannot be assured.
Pull tractor feed
l Set the release lever to the PULL position.
l Load the paper from the front, rear, or bottom entrance.
(The front or bottom entrance is recommended for thick paper or labels.)
l Release the friction feed mechanism.
l Remove the paper-tension unit and attach the pull tractor unit.
l Insert paper from either front or bottom.
l Multi-part paper must be carbonless.
l Do not perform reverse feeds.
Push-pull tractor feed
l Set the release lever to the REAR PUSH/FRONT PUSH position.
l Load the paper from the front or rear entrance.
. Release the friction feed mechanism.
l Remove the paper-tension unit and attach the pull tractor unit.
l Remove any slack in the paper between the platen and the pu11 tractor.
l Precisely adjust the horizontal position of the pull tractor and push tractor.
l Multi-part paper must be carbonless.
l Do not perform reverse feeds greater than l/6”.
l Do not perform reverse feeds after the paper end has been detected.
