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.

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 présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites applicables aux

appareils numériques de Classe B prescrites dans le règlement sur le brouillage radioélectrique édict‚ par le

Ministère des Communications du Canada.

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 Page 16

Understanding SCSI

Connections

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

devices.

SCSI Chain

The SCSI interface allows you to connect up to seven devices (such 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 Connections Page 17

SCSI Cables

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 the SCSI cable connectors are suitable for your

hardware, depending on the maker of your SCSI device and SCSI

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 number 7,

and each of the other devices

must have a different number

between 0 and 6. The EPSON

Expression 800 default SCSI ID

number is 2.

You’ll find the SCSI ID rotary

switch at the rear of the

scanner.

SCSI Termination

The first device and the last device

in the chain (not including the

adapter) must be terminated,

either by a terminator plug or a

termination switch set to ON. No

other device in the chain can

be terminated. The EPSON

Expression 800 has a termination

swtich which is located at the rear

of the scanner. The default

position of the termination switch

is ON. Do not use an external

terminator with the EPSON

Expression 800.

the SCSI ID Number

The scanner’s default SCSI ID number is 2. If you add the scanner to a

system in which one of your SCSI devices already uses SCSI ID 2, you

can change the ID number to an unused number using the rotary switch

at the rear of the scanner. See the table on the next page for a guide to

SCSI ID numbers. Then follow these steps to change the ID number:

1

Turn the scanner off.

2

Use the rotary switch at the back of the scanner to change the SCSI ID

number.

3

Turn the scanner back on.

4

Restart your computer.

Make sure the

scanner is turned off

before changing the

SCSI ID number.

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 properly.

Windows 98, see
