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.
