Scanning Transparencies and Film

Before scanning transparent documents, you need to remove

the scanner’s reflective document mat; this exposes the scanner’s

transparency unit (light source), which is built into the lid.

If you’re scanning slides or film strips, you’ll also need to use

one of the film holders.

Using the Transparency Unit

To use the transparency unit, remove the reflective document

mat by grasping the top of the mat and sliding it up gently, as

shown.

Make sure the cable for the tranparency unit is plugged into the

round connector. If not, turn off the scanner, then connect the

cable as shown.

Using Film Holders

Film has two sides, a shiny base side and a dull emulsion side.

The base side of the film has the film maker’s name and film ID

numbers printed on it. Always place the shiny base side down.

To scan 35-mm film strips, 4 × 5-inch film, or 120/220 (6 × 9-

cm) film, place the film in the correct holder, as shown:

Place the holder with the film onto the scanner. Make sure the

white triangle on the holder points to the upper-right corner of

the scanner.

If you’re scanning 35-mm slides, set the holder on the

scanner first, then place the slides in the holder.

Using EPSON Smart Panel

documents or photos:

1. Place the original document(s) face down on the document

table.

2. Do one of the following to open the Smart Panel:

❏Press the

] Start button on your scanner.

❏Click the Smart Panel icon on the desktop.

❏On a Macintosh,

® you can also open the Apple® menu

and select EPSON SMART PANEL.

The

] Start button is set to open EPSON Smart Panel by

default. However, you can assign the

] Start button to

automatically open any of the Smart Panel applications.

3. Click the icon for your desired scanning application. The

window for that option appears and lets you adjust settings

for your scan. Follow the on-screen steps for each option.

Keep the following in mind when using Smart Panel:

❏If you select Copy or Photo Print, make sure your printer is

turned on and the correct paper type and size is loaded in

your printer.

❏Scan to E-mail requires a MAPI-compliant e-mail program.

(AOL is not MAPI compliant; however, you can select

Scan to File, then use your email software to attach the file
