FCC Compliance Statement for United States Users

This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the 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 and 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.

◗ Reorient or relocate the receiving antenna
◗ Increase the separation between the equipment and receiver
◗ Connect the equipment into an outlet on a circuit different from that to which the receiver is connected
◗ Consult an experienced radio/TV technician for help.

WARNING

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 that 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 cables connected to
unused interfaces.

Changes or modifications not expressly approved by the manufacturer could void the user’s authority to
operate the equipment.

A Note Concerning Responsible Use of Copyrighted Materials

Like photocopiers, scanners can be misused by improper scanning of copyrighted material. Although Section
107 of the U.S. Copyright Act of 1976 (Title 17, United States Code), the “fair use” doctrine, permits limited
copying in certain circumstances, those circumstances may not be as broad as some people assume. Unless
you have the advice of a knowledgeable attorney, be responsible and respectful by not scanning published
material without the permission of the copyright holder.

Understanding SCSI

Connections

Read the following sections to determine how to set up your SCSI
devices.

SCSI Chain

The SCSI inte rf ac e allows you to con nect up to seven de v ic es (su c h as a
scanner, hard disk, CD-ROM, and so on) to the computer. Only the first
SCSI device in the chain is connected to the computer; each of the other
devices is connected to another SCSI device.

Understanding SCSI Connectio ns Page 16

Some SC SI ID
numbers may not
be available for
your system. See
SCSI ID Number
Settings f or details.

SCSI Cable s

The cable you use to attach the scanner to your computer must not
exceed 9.8 feet (3 meters).

If you are connecting multiple SCSI devices to your computer, you
may need to purchase several SCSI cables before setting up your
SCSI chain. Be sure th e SCSI cabl e c onnectors are suitable fo r y our
hardware, depend ing on the mak er of your SC SI device and SC SI
interface board.

To connect the scanner to another SCSI device, the length of cable must
not exceed 19.7 feet (6 meters); otherwise the system may not work
properly.

SCSI ID

Each device has a SCSI ID
number: the SCSI adapter in the
computer is usually num ber 7,
and each of th e other devic es
must have a different number
between 0 and 6. The EPSON
Expression 800 defaul t SCSI I D
number is 2.

You’ll find the SCSI ID rotary
switch at th e rear of the
scanner .

The first device and the last device
in the chain (not including the
adapter) m ust be terminated,
either by a ter m inator plug or a
termination switch set to ON. No
other dev ic e in t he chain can
be termin at ed. The EPSON
Expression 800 has a te rm ination

Do not set the SCSI
ID to an ID number
that is already
assigned to another
device. Otherwise the
computer, scanner,
and other devices will
not operate prope rly .

If you are us ing
Window s 98, see

Setting the SCSI ID Number

The scanner’s default SCSI ID n um ber is 2. If you add the scan ner to a
system in w hic h one of your SCSI dev ic es already uses SCSI ID 2, you
can chan ge t he ID numb er t o an unused num ber using th e rot ary switch
at the rear o f the scanner. See the table on the next page for a guid e t o
