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

1. Make sure the transparency unit cable is connected to the

option interface connector on the back of the scanner.

(If it is not connected, turn off the scanner, connect the

transparency unit cable, then turn the scanner back on.)

2. Lift the scanner lid all the way up and pull the reflective

document mat up and off of the scanner lid, as shown.

3. If you are scanning film or negatives, open the cover, then

slide the film into the corresponding holder, with the film’s

shiny base side facing down. (If you are scanning slides, go

to step 6.)
