Using the SA-21
The SA-21 can be used to scan 35-mm film in strips of two to six frames (for information on
film that can not be used in the SA-21, see pages 102–104 of this manual).
1 After confirming that the scanner is ready (the scanner is ready when the status
LED is not blinking), insert the SA-21 into the scanner.
Open the sliding cover on the front of the scanner and slide the SA-21 smoothly into the
adapter slot until it is fully inserted. The status LED will blink a few times and then glow
steadily.
Removing the Adapter
Attempting to remove the adapter without ejecting the film can result in the adapter becoming
separated from the connectors at the rear of the adapter slot, interfering with scanning. If you
have attempted to remove the adapter before ejecting film, push the adapter back into the slot
slightly to ensure that the connection is not interrupted. Do not attempt to remove the adapter
by force, as this could damage both the adapter and scanner.
