Lights and Buttons

The scanner has three indicator lights and two buttons. Light

status and button functions are described in the tables below.

N= on,

O= off,

F= flashing

Transporting the Scanner

When you transport the scanner a long distance or store it for

an extended time, follow the steps below to secure the

carriage:

1. Make sure the transportation lock on the back of the

scanner is in the UNLOCK position.

2. Locate the SCSI ID rotary switch on the back of the

scanner. Align the dot on the switch with the asterisk (*)

setting.

3. If you’re using a transparency unit or auto document feeder,

remove it and replace the scanner cover.

4. Turn on the carriage and wait until the carriage moves to

the home position (toward the back of the scanner). Then

turn off the scanner.

5. Slide the transportation lock to the LOCK position.

If the carriage doesn’t automatically return to the home

position, slowly raise the front of the scanner and hold it up

until the carriage comes to rest in the home position. Then

slide the transportation lock to the LOCK position.

Transporting the Transparency Unit

After you’ve removed the transparency unit from the scanner,

prepare it for shipping as follows:

1. Slowly raise the front of the transparency unit to allow the

lamp assembly to slide to the back of the unit. Wait until

the lamp assembly comes to rest.

2. Reinstall the transparency unit’s shipping screw in the hole

marked CLAMP.

Selecting a Driver and Settings

Here is a brief overview of the scanning steps using LaserSoft®

SilverFast™Lite and EPSON TWAIN Pro. In both of the

following illustrations, the Macintosh interface is shown; the

Windows steps are the same.

If you select Expression 800 (32-bit) (Windows) or

Expression800 (Macintosh) as your scanner source, you see

the SilverFast Lite window:

If you select EPSON TWAIN Pro(32-bit) (Windows) or

EPSON TWAIN Pro (Macintosh) as your scanner source, you

see the EPSON TWAIN Pro window.

Here are some recommended settings for different types of

scans.

* If the final output is for on-screen viewing (for example, on a

web page), select 72 dpi for your resolution.

** Automatically selects Text Enhancement Technology (TET) as

your B/W option.

*** If you are enlarging your image, you must manually increase the

resolution (dpi) proportionally to maintain the resolution of your

original.

Photoshop 5.0 LE Macintosh

Configuration Tips

To avoid memory problems on the Macintosh when using the

scanner with Photoshop 5.0 LE, follow these

recommendations:

1. Set Preferred memory in Photoshop 5.0 LE to twice the

suggested memory size. (Select the Photoshop 5.0 LE

desktop icon, then select File, Get Info.)

2. Turn Virtual memory OFF. (From the Apple icon, select

Control Panel, Memory.)

3. Assign a scratch disk. (Start Photoshop 5.0 LE, then select

File, Preferences, Plug-ins & Scratch Disks.)

4. Restart your Macintosh.

See the electronic Photoshop 5.0 LE manual on your

Photoshop 5.0 LE CD-ROM for detailed information.

Scanner Bundle Kits

The scanner is available in three models: Executive, Artist, and

Professional. The Professional model includes a transparency

unit.

Check with EPSON for information about the configuration

of each scanner bundle kit.
