You can
load originals of different sizes, paper types, and thicknesses at
one time in the input tray. Just make sure they meet the original
document specifications.
Caution:
Do not load photos, or valuable original
documents or artwork, directly into the input tray. This may
wrinkle or damage the original. Load these originals using an
optional carrier sheet.
Note: Photos
scanned using a document scanner may not have the same color depth
as the original. Use a flatbed photo scanner with the optional
flatbed scanner dock (ES-400 II) to achieve the best
color reproduction of photos.
