Note:
Make sure the unit is completely closed, otherwise an option error
results and you cannot scan the document, nor attain proper colored
images.
When previewing images on EPSON TWAIN of negatives scanned
using a film holder, the color may appear odd as the frame of the film
holder is perceived as white, causing your scans to appear darker.
To see the correct color, click and drag the mouse over an area, then
click the zoom preview button.
You can move and adjust the position of 35mm film by sliding the
strips in the film holder so the frames you want to scan are positioned
in the window.

To remove a film holder from the document table, slide it left or right
