Optional Transparency Unit
Specifications
The transparency unit (B813152) allows you to scan positive
and negative transparent materials—35 mm slides, 35 mm
filmstrips, and film up to 8.5 × 11.7 inches in size. In addition
to four film guides, it comes with a reflective document mat
that allows you to alternate between scanning transparent
materials and normal reflective (paper) documents.
