Button Function
OPERATE Turns the scanner on and off.
RESET
Resets the scanner after an error. (Pressing this button
while scanning is in progress stops the scanner and
may cause an error.)
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.

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.
