Using Film Holders

Scanning Transparencies and Film

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.

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.

To scan 35-mm film strips, 4 × 5-inch film, or 120/220 (6 × 9cm) film, place the film in the correct holder, as shown:

If you’re scanning slides or film strips, you’ll also need to use
one of the film holders.

Using the Transparency Unit
120/220 (6 × 9-cm)
film

To use the transparency unit, remove the reflective document
mat by grasping the top of the mat and sliding it up gently, 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.

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.

Keep the following in mind when using Smart Panel:

If you’re scanning 35-mm slides, set the holder on the
scanner first, then place the slides in the holder.

❏ 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
to your message.)
For instructions on using each of the Smart Panel applications,
see the online help for EPSON Smart Panel.

❏ Press the ] Start button on your scanner.
❏ Click the

Smart Panel icon on the desktop.
