Using the Film Guides

You can use the four film guides that came with the scanner to scan 35 mm slides, strips of 35 mm negative or positive film, 120-size or 220-size format film, and

4 × 5-inch film.

When using the film guides, be sure the transparency unit is completely closed or an error will occur and you will be unable to scan.

Store the reflective document mat in the transparency unit pocket when not in use.
