Can scanners scan transparencies? Yes. Some scanners have Transparency Media Adapters (TMA) built into the lid of the scanner, while others (better ones) replace the lid of the scanner when needed. New tray TMA's pull out from the middle of the scanner and produce some of the nicest transparencies. When evaluating a TMA make sure of the following:
A) Will the TMA be able to do the size of the transparent image?
B) Is the TMA just a lit light source or does it move in sync with the scanning lamp?
C) Is the TMA built into the scanner (such as as tray holder) or is it something that attaches and plugs into the rear of the scanner and replaces the lid?
